[Bug 42159] Re: If an existing swap partition is marked to be formatted, it gets "corrupted" and unused in the final installed system, because the LiveCD is using it

[Githlar]

I just got a report from somebody on askubuntu.com that may be related
to this bug.

The problem:
If you check the "Encrypt home folder" box while installing, for some reason Ubiquity uses the first swap it finds as encrypted swap (and therefore has to "format" it). In his case, he was installing to a USB flash drive and it found the swap on his main installation and corrupted it. Every time he would boot his flash drive it would corrupt his main installation's swap.


The solution:
Because an entry was placed in /etc/crypttab, the swap got re-"formatted" (secure wiped) for use with eCryptfs's encrypted swap. Removing the entry solved the problem and he was able to boot his USB without corrupting his swap space.

Title:
  If an existing swap partition is marked to be formatted, it gets
  "corrupted" and unused in the final installed system, because the
  LiveCD is using it

Status in “ubiquity” package in Ubuntu:
  Confirmed

Bug description:
  Just installed Dapper using the LiveCD beta2. I already had a swap partition in my system, and the LiveCD automatically used it.
  Because of this, when I chose to format this swap partition during installation, this fails, but the instalation continues.

  In the final installed system, the swap partition was "mangled" and
  couldn't be used.

  To fix this, I manually delete and recreate the swap partition.

  I've attached my /var/log/installer/syslog file.
