On some deployments install fails as we keep one FD open
during install. This leads to hangs when Anaconda
'post' stage returns.
On other deployments install fails as udev sometimes creates
multiple links to the same devices in /dev/disk/by-path.
We iterate through this list and, because they are not unique,
we try to run flocks multiple times for the same device.
Locking a device multiple times doesn't work, the second
flock waits for first lock to release.
This commit:
o removes 'exec {stdout}>&1' from ks-functions.sh so it no
longer opens FDs in 'post' stage. For the pre stage we open
it only when needed;
o makes sure that list of storage devices is unique;
o increases timeout of udevadm settle from its default of 180s
to 300s, the value used throughout Anaconda. This helps
with slower hardware.
