The CI setup did not change recently.
All standard-CI jobs run inside mock (chroot) which is stored on top
of a regular FS, so they should not be affected by the slave OS at all
as far as FS settings go.

Hi all,
It seems that the CI setup has changed, and /var/tmp is using now tempfs.
This is not compatible with vdsm tests, assuming that /var/tmp is a real file
system. This is the reason we do not use /tmp.
We have lot of storage tests using directio, and directio cannot work on
tempfs.
