[Bug 1099349] Re: mountall 2.36.3 hangs in recovery-menu (lvm; mountall 2.36 has no issue)

[Michael Wisheu]

Hi Steve,

I've upgraded my Precise VM with the mountall issue to Quantal and confirmed that the issue is also present under Quantal for this VM. Then I've installed mountall 2.42ubuntu0.4 and the issue is resolved.
>From my point of view mountall 2.42ubuntu0.4 looks good for Quantal to me.

Best,

Michael

Bug description:
  [Impact]
  Following the mountall SRUs for bug #643289, mountall --no-events does not work correctly; the lack of events causes mountall to not finish.  This breaks the recovery mode, which invokes mountall --no-events.

  [Test case]
  1. Boot Ubuntu using the 'recovery mode' option.
  2. Choose the 'Enable networking' option.
  3. Observe that mountall hangs.
  4. Reboot and install mountall from -proposed.
  5. Boot Ubuntu using the 'recovery mode' option.
  6. Choose the 'Enable networking' option.
  7. Confirm that mountall no longer hangs.

  [Regression potential]
  Minimal; the code changes should only have any effect when mountall is called with --no-events, which is only done in the recovery menu, and that's currently broken.

  
  Fresh Ubuntu 12.04.1 amd64 install with the following partition layout / lvm setup:
  $ lsblk
  NAME                            MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
  sr0                              11:0    1  1024M  0 rom
  sda                               8:0    0    20G  0 disk
  ├─sda1                            8:1    0   243M  0 part /boot
  ├─sda2                            8:2    0     1K  0 part
  └─sda5                            8:5    0  19.8G  0 part
    ├─u1204--64-swap_1 (dm-0)     252:0    0  1020M  0 lvm  [SWAP]
    ├─u1204--64-root (dm-1)       252:1    0   7.6G  0 lvm  /
    └─u1204--64-usr--local (dm-2) 252:2    0  11.1G  0 lvm  /usr/local

  The installation works as expected and there are no imminent issues during normal usage.
  The issue is with the recovery menu. If someone boots into a rescue entry in the boot menu the rescue menu appears as expected but all entries that remount the root volume rw will hang on mountall.
