[Bug 1168974] Re: friendly-recovery tool hangs trying to do almost anything with encrypted swap partition

[Greg Ward]

Hmmmm: if I disable my encrypted swap partition (by modifying
/etc/fstab), this problem goes away. Definitely seems like friendly-
recovery has problems with encrypted swap.

** Summary changed:

- friendly-recovery tool hangs trying to do almost anything (e.g. "Enable networking")
+ friendly-recovery tool hangs trying to do almost anything with encrypted swap partition

Title:
  friendly-recovery tool hangs trying to do almost anything with
  encrypted swap partition

Status in “friendly-recovery” package in Ubuntu:
  New

Bug description:
  Steps to reproduce:
  1. boot into recovery mode
  2. from the "Recovery Menu", select "Enable networking"
  3. when warned that continuing will remount / in read/write mode,
     select "Yes"

  Expected behaviour:
  - system runs fsck on root FS, which quickly succeeds (because the
    FS is clean -- I ran fsck manually quite recently)
  - system remounts / in read/write mode
  - system enables networking
  (I would expect all this to take < 1 sec)

  Actual behaviour:
  - system runs fsck, which quickly succeeds
  - and then it hangs: there's no indication of what it's doing and no
    feedback of any kind (screenshot attached: recovery-mode-hang.png)
  - there's also no way to dig around and figure out what's going on:
    network interfaces aren't up and no other text consoles are active

  My lame attempt at a workaround: hit Ctrl-C. This doesn't help. A
  bunch of text flies by, some of which might be relevant to the hang
  (screenshot attached: recovery-hang-encrypted-swap.png). Then the
  system goes into "failsafeX" mode, which doesn't work for me (probably
  a separate bug).

  I don't think there is anything special about the "Enable networking"
  option here. I've seen very similar (identical?) behaviour trying to
  run the "clean" and "dpkg" options after booting into recovery mode.
