[Pkg-samba-maint] Bug#408394: umount.cifs: mtab symlink is replaced with regular file

[Radu Cristescu]

Package: smbfs
Version: 3.0.23d-4
Severity: grave

umount.cifs removes /etc/mtab even if it's a symlink to /proc/mounts
and writes a regular file instead

I'm setting the Severity to "grave" because I think losing a symlink
can be considered "data loss" (the symlink is "data") and using a
regular file for mtab is not an option in my case.

Here's a session (only the relevant output, for brevity):

arwen:~# ls -l /etc/mtab
lrwxrwxrwx 1 root root 12 2007-01-25 17:38 /etc/mtab -> /proc/mounts
arwen:~# cat /proc/mounts
//10.0.0.150/builds /mnt/150/builds cifs rw,mand,unc=\\10.0.0.150\builds,username=root,rsize=16384,wsize=57344 0 0
//10.0.0.150/repositories /mnt/150/repositories cifs rw,mand,unc=\\10.0.0.150\repositories,username=root,rsize=16384,wsize=57344 0 0
arwen:~# umount /mnt/150/builds
arwen:~# ls -l /etc/mtab
-rw-r--r-- 1 root root 1281 2007-01-25 17:39 /etc/mtab

Thanks.
