[Pkg-sysvinit-devel] Bug#476698: killall5 should not kill fuse filesystems

[Goswin von Brederlow]

Package: sysvinit-utils
Version: 2.86.ds1-56
Severity: wishlist
Tags: patch

Hi,

we use fuse-unionfs for /etc and /usr on a pool of systems. When
rebooting killall5 will kill all processes execpt init and itself
causing the fuse filesystems to be killed without umount. In our case
the next access to /etc or /usr will block because there will be no
process left to service the request.

The attached patch adds a test for fuse filesystem and leaves them
alone. This allows any of the many fuse filesystems to be used for
system directories.

It also changes the cwd to /proc and changes readproc() to use
relative paths. This avoids access() calls to / that would deadlock if
/ is a fuse filesystem.

MfG
