update-manager needs to handle mount/nfs-common transition for gutsy

[LaMont Jones]

Binary package hint: update-manager

with 2.13, upstream for util-linux dropped nfs support, which is now handled by nfs-common (which now delivers mount.nfs)

Debian fails with the code below in mount.preinst, update-manager should make sure it's dealt with for gutsy:
        if [ Debian = "$DISTRO" ]; then
          if [ -f /var/lib/dpkg/info/nfs-common.list ] && [ -f /proc/mounts ]; then
              NFS_IN_USE=$(sed -n '/^[^ ]* [^ ]* nfs /p' /proc/mounts)
          else
              NFS_IN_USE=""
          fi
          if [ -n "$NFS_IN_USE" ] && [ ! -x /sbin/mount.nfs ] ; then
              cat << EOF
You have NFS mount points currently mounted, and this version of mount
requires that nfs-common be upgraded before NFS mounts will work.

Aborting install.
EOF
              exit 1
          fi
        fi

If there are active nfs mounts, then nfs-common (>= 1:1.1.0-13) must be installed.

It should perhaps be noted that sfs also counts as an nfs mount, even though the user may not think of it as such.

<lamont> and then mix that with debian #443466
<ubotu> Debian bug 443466 in mount "mount: upgrade fails if nfs-common is in removed but not purged" [Normal,Open] http://bugs.debian.org/443466

[LaMont Jones (lamont)]

443466 does not apply to ubuntu, since the check is only done on Debian. (and fixed in 2.13-7, which has not been propagated to ubuntu yet.)

Likewise, it may be that this is "not a bug" in ubuntu, since feisty dpkg has Breaks: support, and therefore the ubuntu uploads indicate that mount Breaks: nfs-common (<<1:1.1.0-7), which (I believe) will cause nfs-common to be upgraded in the same pass as mount being installed.

If my understanding is correct, please close the bug. If it's not, please remind me to update the GutsyGibbon/ReleaseNotes page.

[Michael Vogt (mvo)]

If feisty nfs works without nfs-common is installed, then update-manager needs to ensure that there is a transition by checking /proc/mounts for nfs mounts.

If there is no way in feisty to have nfs mounts without nfs-common, then the breaks should ensure the right ordering.

My tests indicate that nfs mounting does work in feisty without nfs-common so I guess transitional code is required.

update-manager (1:0.76) gutsy; urgency=low

  * DistUpgrade/DistUpgradeCache.py:
    - ensure that the util-linux -> nfs-common transition
      happens (LP: #141559)

  [ Jonathan Riddell ]
  * DistUpgrade/DistUpgradeViewKDE.py:
    - copy Xauthority file if necessary
