Subject: initscripts: umountroot fails if / is bind-mounted somewhere
Package: initscripts
Version: 2.86.ds1-5
Severity: wishlist
Tags: patch
I ran into a subtle problem with my amd64 computer which drove me crazy for
a while, until I tracked it down. Upon shutdown or reboot, the root
filesystem would not be unmounted nor be remounted readonly, with the result
that I always had a dirty root filesystem. It was not a big issue, since it
always had time to settle and write buffers to disk, but it was annoying.
I finally found out that this was due to having the root director
bind-mounted by default on a chroot cage (I run an amd64 bit system and have
a chrooted i386 installation for compatibility reasons). Upon shutting down,
when trying to umount the root filesystem umountroot found the line saying
/ /ia32/amd64 none bind 0 3
and tried to umount that instead of the root filesystem, which remained
mounted rw. Since in the sid version of mount it is possible to specify that
the command must be applied only to filesystems mounted with (or without)
some given options, I solved my problem by replacing the line
mount -n -o remount,ro /
in the umountroot script with
mount -n -O no bind -o remount,ro /
With the above, the root filesystem may have been bind-mounted any number of
times and it will cause no problems, since the bind mounts have been
umounted already at this stage and the "-O no bind" options tell mount to
ignore any entries referring to bind mounts.
While this is a rather peculiar problem, it is one which is common to any
people who bind-mount the root filesystem anywhere, and is trivial to fix
with no side-effects, with the one-liner above. It would also be nice to
come up with a solution which works on sarge as well as with sid, but I did
not dig into it since I run sid...
best regards
Giacomo

Changes:
sysvinit (2.86.ds1-11) unstable; urgency=low
.
[ Thomas Hood ]
* rcS(5): Improve
* sulogin(8): Improve; mention -t option (Closes: #186880)
* bootlogd(8): Improve; mention need for PTY support
* initscripts postinst: Update to reflect script name changes
* initscripts: Harmonize PATH settings
* checkroot.sh: Don't check for need to start /sbin/update.
We don't support pre-2.4 kernels any more.
* checkroot.sh, mountall.sh: Run swapon with -v if VERBOSE!=no
* Remove obsolete lintian overrides
* Previous release also
closes: #258290 "bootlogd: Bad file descriptor"
closes: #327865 "bootlogd stopped working"
closes: #328764 "bootlogd fails to start"
.
[ Petter Reinholdtsen ]
* Time to upload all these changes into unstable (Closes: #341075)
* Revert default VERBOSE value to "yes" to reduce the amount of
user visible changes in this upload.
.
sysvinit (2.86.ds1-10) experimental; urgency=low
.
[ Thomas Hood ]
* bootclean: Adapt from old bootclean.sh; handle return status more
carefully; print diagnostic messages on failures; eliminate use of
subshells; add comments; improve deletion code
* bootclean: Always rm /tmp/.X*-lock
* mountall.sh: Eliminate unnecessary check for pre-2.4 Linux kernel
* mountnfs.sh, mountall.sh: Choose different names for intnl. functions
* mountnfs.sh: Only sleep 1 second after starting portmap; note that
the code to start portmap will disappear someday
* various scripts: Make more messages depend on VERBOSE being != "no"
* various scripts: Handle return status more carefully
* various scripts: Eliminate unnecessary uses of subshell
* mountvirtfs -> mountkernfs.sh; mountdevsubfs -> mountdevsubfs.sh;
mountvirtfs now calls the above two (for backward compatibility);
mtab.sh now runs mountkernfs.sh and mountdevsubfs.sh to update
the mtab file after mountall.sh.
* /etc/init.d/rc: Restore PATH after sourcing an initscript
* debian/rules:
+ Use ':', not the deprecated '.' between owner and group names
in chown commands
+ Use '-o root' with install
* /etc/init.d/README: Note that /etc/init.d/*.sh must have '#!/bin/sh'
and must follow policy 10.4.
* Override lintian and linda warnings
.
[ Ubuntu backports by T.H. ]
* During shutdown and reboot take the progress bar from 100 to 0
* Reduce diff with 2.86.ds1-6ubuntu1
.
Thanks to Mark Hatle and Marco d'Itri for help with this release.
.
sysvinit (2.86.ds1-9) experimental; urgency=low
.
[ Thomas Hood ]
* Split mountdevsubfs out of mountvirtfs and run it at S04 and S37.
[Note added in 2.86.ds1-10: these scripts were renamed]
This should not behave any differently, but the split will allow
packages that futz with /dev to do this at S03.
* umountfs: Only run umount if there is something to unmount
(Closes: #345272)
* urandom: Set PATH so that find can be found (Closes: #345273)
* init: 64_init_set_PATH.dpatch: Set PATH if it's unset on re-exec
(Closes: #345370)
* init: 65_init_u_in_06.dpatch: Allow 'telinit u' in runlevels 0, 6
(Closes: #345719) People running Debian from unusual media (such
as filesystems embedded in NTFS files) are wanting to unmount
/sbin at the last moment and need to re-exec init to do so.
* umountroot: Remount ro with -f on GNU/kFreeBSD (Closes: #344547)
* checkroot.sh, checkfs.sh: Pause for five seconds if sulogin fails
so that the user can see the error message (Addresses #337444)
* Include /var/log/fsck/ in initscripts package (Closes: #346139)
* Replace /lib/init/functions.sh with /lib/init/mount-functions.sh
for use by mountvirtfs and mountdevsubfs
* various initscripts: Clean up code that reads fstab
* various scripts: Redirect which program's stderr to /dev/null
since the GNU version prints an error message when the command is
not found (Closes: #345321)
* /etc/default/rcS: Make VERBOSE and DELAYLOGIN default to "no"
* /etc/default/rcS: Remove descriptions of variables; leave behind
a reference to rcS(5). This eliminates the problem of comments
becoming outdated without our being able to update them.
* Remove obsolete docs
* Make initscripts Depend on mount >= 2.11x-1 (Closes: #345968)
* Remove obsolete dependencies on bsdutils, coreutils, dpkg, kbd and
util-linux: the versions in question are older than oldstable, so
any newly installed system and any system that has upgraded to
sarge (or even woody) satisfies the constraints.
* Remove obsolete dependency on the last package: last was forced off
systems when they upgraded to buzz
* Add Replaces to Conflicts: mdutils which no longer exists even in
oldstable
* initscripts postinst: Remove obsolete GMT-to-UTC code: this
conversion was performed when systems were upgraded to potato
* sysvinit: Depend on libc6 rather than Pre-Depending on it; we don't
do anything special in the preinsts any more
* Correct documentation of init's -e and -t options
* Tweak descriptions
* Add READMEs for remaining runlevel dirs (Closes: #242957)
* Previous release also
closes: #227540 "skeleton: Don't include /usr/local/* in PATH"
closes: #346415 "mountnfs.sh doesn't work with the "bg" mount option"
.
[ Petter Reinholdtsen ]
* sysv-rc: Fix some typos in the startpar handling. (Closes: #345269)
* Add code to detect and report bad 'exit' calls in init.d scripts,
if they kill /etc/init.d/rc.
* Make sure sourcing work with dash /bin/sh, by using 'set $action'
to pass arguments to the script. (Closes: #345267)
.
Thanks to Mark Hatle for help with this release.
.
sysvinit (2.86.ds1-8) experimental; urgency=low
.
[ Thomas Hood ]
* Omit /run until we are sure it's needed (Closes: #344001)
* Previous release also
closes: #338736 "mountvirtfs: Succeeds in various cases it should fail"
closes: #342160 "checkroot.sh ignores fsck result"
closes: #342744 "checkroot.sh sources mountvirtfs, yet supplies arguments"
* Use /proc/mounts instead of /etc/mtab when unmounting (Closes: #338801)
* Check for files under mountpoints more thoroughly
* initscripts.postinst:
+ Don't fail to install on file-rc systems (Closes: #343993)
+ Don't fail to install in chroots (Closes: #344089)
* No longer keep the dynamic nologin flag file on the root filesystem;
instead, keep it at /var/lib/initscripts/nologin. Note to admins:
initscripts's postinst symlinks /etc/nologin to the latter location.
To switch login delaying on or off permanently, set DELAYLOGIN=no in
/etc/default/rcS and either create or delete (respectively)
/var/lib/initscripts/nologin.
* mountvirtfs: Mount /dev/shm earlier; move long comment to README.Debian
* Add 45_pidof_symlink.dpatch: Make pidof an absolute symlink
(Closes: #343862)
* debian/rules, 30_strip.dpatch: Strip .comment section from executables
(Closes: #343863)
* In umountfs, run umount with -f (Closes: #344547)
.
[ Petter Reinholdtsen ]
* Enable the startpar option as it should work now that .sh scripts
are serialized. The clock should no longer jump while startpar
is used.
.
sysvinit (2.86.ds1-7) experimental; urgency=low
.
[ Petter Reinholdtsen ]
* Add commented-out code to /etc/init.d/rc for sourcing
*.sh scripts for runlevel 'S'. This is preparation for fixing
#339955. Actually fixing it has to wait until other packages
remove "exit" from their .sh scripts.
* Implement progress bar support for splash screen. Enabled when
usplash_write is in PATH. Patch from Scott James Remnant and Ubuntu.
.
[ Thomas Hood ]
* *.sh: Make sure that these do their thing when they aren't given any
command line arguments (as is the case when they are sourced)
* initscripts: Improve use of log_* functions
(Closes: #55143, #116366, #323749)
* bootclean.sh: Do not delete symlinks-to-directories from /var/run/
(Closes: #272066)
* checkroot.sh: Fix double printing of 'Done checking root file system';
mountall.sh: Fix chopped-up printing of mount information
(Closes: #339979, #331397, #341097 and presumably closes: #332309)
* checkroot.sh, checkfs.sh: Save fsck logs (Closes: #189356)
Thanks to Theodore Y. Ts'o.
* checkroot.sh, mountvirtfs: Eliminate use of dir_writable in order to
try to please selinux (Closes: #333836)
* checkroot.sh: Only run findfs for mount on / (Closes: #275680)
Thanks to Cameron Hutchison for the patch.
* mountall.sh, mountnfs.sh: Split call to bootclean out into separate
script called at the next sequence number (Closes: #286479)
* bootmisc.sh: Shorten motd header (Closes: #340017)
* bootmisc.sh: Store dynamic motd in /var/run/ and make /etc/motd a
symbolic link. The EDITMOTD variable no longer has any effect; to
disable updating of the motd just point the /etc/motd symlink to a
static file such as /etc/motd.static.
* bootmisc.sh: Rotate dmesg log with savelog (Closes: #237074)
and chgrp adm.
* umountroot: Change mount command in order to exclude bind mounts of
the root directory (Closes: #339023)
* Replace /etc/rc1.d/20single by /etc/rc1.d/S30killprocs and
/etc/rc1.d/S99single so that packages can insert scripts to do
things between the "killall5" in the former and the "exec init -t1 S"
in the latter. This may help to address #145280.
* umountfs: Unmount tmpfs before swapoff and other fs's afterwards
(Closes: #328582, hopefully without reopening #84782)
* Make stop-bootlogd a distinct script rather than a symlink to bootlogd.
Give it its own LSB header.
* Add stop-bootlogd-single initscript to stop bootlogd in "single" mode
(Closes: #213028, #220025)
* checkfs.sh: Implement FSCKTYPES (Closes: #89481) Set, e.g.,
FSCKTYPES="ext2,msdos" to fsck only file system types ext2 and msdos
See fsck(8) for syntax. FSCKTYPES="none" disables fsck of file
systems (other than the root filesystem) altogether.
* all initscripts: Set variables using common script
* all initscripts: Fix usage messages
* all initscripts: Allow VERBOSE to be set via the INIT_VERBOSE=yes
kernel argument (Closes: #286082) Experimental. The name of the
kernel argument may change in the future if we decide to implement
this more generally.
* Improve skeleton initscript
* all scripts: Clean up; standardize indentation
* all scripts: Use the "which" program to test for executability
* initscripts: Experimentally include /run; include /sys in Linux
builds
* mountvirtfs: Mount a tmpfs on /run
* mountvirtfs: Warn if mount point has stuff under it (Closes: #95390)
* initscripts postinst: Mount virtual filesystems
* initscripts preinst: Remove ancient /etc/init.d/boot conversion code
(Closes: #343596)
* default config files: Clean up comments
* Make initscripts Depend on debianutils >= 2.13.1 in order to prevent
#295850. Note that debianutils also has to be >= 2.12.0 so that the
"which" program is available in /bin.
* Remove currently unneeded sysvinit Dependency on coreutils
(Closes: #316423)
* pidof: If the program is specified with a path, don't match processes
of programs run from different paths (Closes: #160329)
* init: 40_selinux.dpatch: Remove superfluous printf argument
* init: Add 63_init_longer_procname.dpatch (Closes: #336172)
* init.8: Mention that entering runlevel 1 kills all processes
(Closes: #238861)
* update-rc.d.8: Mention that update-rc.d will not create multiple start
or multiple stop symlinks for a service in a single runlevel directory.
(Closes: #330155)
* Update FSF address
