[Pkg-ltsp-devel] Bug#690267: ltsp-client: nbd swap files are not removed from the server if swap encryption is enabled

[George Kiagiadakis]

Package: ltsp-client
Version: 5.4.2-2
Severity: normal

Dear Maintainer,

NBD swap files seem to be encrypted by default (if no encryption
option is specified).
However, the nbd-disconnect script does not handle encrypted swap files.
Specifically, it tries to do "swapoff /dev/nbd1" where it should actually
be doing swapoff on /dev/mapper/swap0 and removing the dm-crypt mapping with
cryptsetup.

The problem is that since nbd-disconnect fails, the swap file is not
properly removed from the server.

As a workaround, setting ENCRYPT_SWAP=False in lts.conf solves the issue.
