[Pkg-samba-maint] Bug#589218: cifs-utils: "mount -a" mounts cifs shares multiple times (+1 time for each call of "mount -a")

[Joerg]

Package: cifs-utils
Version: 2:4.5-2
Severity: normal

With every call of "mount -a" (which is trigered by /etc/network/if-up.d/mountnfs)
all cifs shares are mounted again.
On a fresh booted system "mount" returns
/dev/sda1 on / type ext3 (rw,noatime,errors=remount-ro)
tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
udev on /dev type tmpfs (rw,mode=0755)
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620)
/dev/sda3 on /home type ext4 (rw,noatime)
fusectl on /sys/fs/fuse/connections type fusectl (rw)
binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev)
//mars.my.local.net/bu_joerg/ on /backup type cifs (rw,mand,noexec)
//mars.my.local.net/GC/ on /home/GC type cifs (rw,mand,noexec)
//mars.my.local.net/bu_joerg/ on /backup type cifs (rw,mand,noexec)
//mars.my.local.net/GC/ on /home/GC type cifs (rw,mand,noexec)
//mars.my.local.net/bu_joerg/ on /backup type cifs (rw,mand,noexec)
//mars.my.local.net/GC/ on /home/GC type cifs (rw,mand,noexec)
//mars.my.local.net/bu_joerg/ on /backup type cifs (rw,mand,noexec)
//mars.my.local.net/GC/ on /home/GC type cifs (rw,mand,noexec)

grep cifs /etc/fstab
mars.my.local.net:GC    /home/GC        cifs    _netdev,nodiratime,noexec,rw,nounix,\
  nosfu,noserverino,uid=joerg,gid=joerg,ip=192.168.1.1,password=xxxxxxx 0       0
mars.my.local.net:bu_joerg      /backup cifs    _netdev,nodiratime,noexec,rw,nounix,\
  nosfu,noserverino,uid=joerg,gid=joerg,ip=192.168.1.1,password=xxxxxxxx        0       0

This bug seems to be related to 586009 (mount.cifs appends trailing slash to share
name in mtab, prevents user unmounts)

If I change fstab (as suggested in 586009) to
//mars.my.local.net/GC/
instead of
mars.my.local.net:GC
then "mount -a" will not mount the share several times.
