[Bug 1155222] Re: Cryptsetup initramfs wants EVMS - Bug in /usr/share/initramfs-tools/scripts/local-top/cryptroot

[Swâmi Petaramesh]

I may have been a little quick in reading the code.

I hadn't ever see any message about EVMS before upgrading from Quantal
to Raring Alpha, so I assumed something had changed in between... But
you're right, I just checked and the same piece of code is present in
Quantal...

The "sometimes" is real, and I saw that this part of code suggest
something that is called when the device "hasn't shown up yet", and I
saw in the past these kind of scripts have trouble with devices taking a
while to show up... Sometimes it works, sometimes not.

In my case, either my machine boots like it always did before, or it
stops forever on this EVMS message... Until I reboot it, and then,
either it works , or I get the same message again...

My machine's HD is rather new and passes all SMART tests, BTW ;-)

Title:
  Cryptsetup initramfs wants EVMS - Bug in /usr/share/initramfs-
  tools/scripts/local-top/cryptroot

Status in “cryptsetup” package in Ubuntu:
  Incomplete

Bug description:
  This bug has been reported upstream both to dm-crypt at saout.de and pkg-
  cryptsetup-devel at lists.alioth.debian.org

  I've recently upgraded one of my fully encrypted systems from Ubuntu
  12.10 to 13.04 Alpha, and was surprised to see my system sometimes
  fail to boot, complaining it cannot find evms_activate.

  I just checked and noticed a logic error in /usr/share/initramfs-
  tools/scripts/local-top/cryptroot : If the crypto source is
  unavailable (script line 205) it then tries to activate both LVM and
  EVMS (line 160), AND EXITS IN ERROR IF EVMS IS NOT AVAILABLE on
  system. It doesn't give a shit trying to guess whether EVMS is needed
  or not, it plain fails and exits.

  This really looks like a serious bug - that has started preventing my
  system from booting randomly at times... - and needs a fix, especially
  taking into consideration that EVMS is essentially and obsolete,
  abandoned system, that will thus be available on very few systems,
  with good chances that this bug will then be triggered...
