[Pkg-sysvinit-devel] Bug#581207: initscripts: checkroot.sh check failure

Tue May 11 16:17:16 UTC 2010
Package: initscripts
Version: 2.87dsf-10
Severity: important
Root filesystem check fails. Standart fsck.ext4 help message is being
printed (with list of options), fs mount ro, and root password is being
asked.
The command, which fails:
logsave -s $FSCK_LOGFILE fsck $spinner $force $fix -t $roottype $rootdev
The problem is that $roottype and $rootdev are "none". Both.
The kernel is built from debian linux-source package, without initrd
(make localyes config)
-- System Information:
Debian Release: squeeze/sid
APT prefers testing
APT policy: (500, 'testing'), (500, 'stable')
Architecture: i386 (i686)
Kernel: Linux 2.6.32 (SMP w/2 CPU cores)
Locale: LANG=ru_RU.UTF-8, LC_CTYPE=ru_RU.UTF-8 (charmap=UTF-8)
Shell: /bin/sh linked to /bin/dash
Versions of packages initscripts depends on:
ii coreutils 7.5-6 GNU core utilities
ii debianutils 3.2.2 Miscellaneous utilities specific t
ii libc6 2.10.2-6 Embedded GNU C Library: Shared lib
ii lsb-base 3.2-23.1 Linux Standard Base 3.2 init scrip
ii mount 2.16.2-0 Tools for mounting and manipulatin
ii sysv-rc 2.87dsf-10 System-V-like runlevel change mech
ii sysvinit-utils 2.87dsf-10 System-V-like utilities
Versions of packages initscripts recommends:
ii e2fsprogs 1.41.11-1 ext2/ext3/ext4 file system utiliti
ii psmisc 22.11-1 utilities that use the proc file s
initscripts suggests no packages.
