FreeNAS Code

Temporarily workaround an issue where storage.forms doesn't expect an
exception from the model. This can happen if the volume have been
removed with bruteforce.

Add the super cool Exuberant ctags to the debug build.

1. Fix a potential getattr failure (noticed by delphij).
2. Remove unnecessary try-except-raise logic.
3. Be consistent and use f is None, instead of not f,
even though both constructs are usable (for most
intents and purposes).

Print the usage message to stderr and call sys.exit() instead of accessing the sys.exit attribute.

Be more picky on swap device, it has to be a character device at least.

NFS can be disabled from the global services tab so don't be too smart
when figuring whether we need to enable these daemons.

This should fix ticket 619.

remove code duplication by using notifier's method
reboot system after config restore

use same factory reset procedure for GUI as for netcli

Factory reset now runs syncdb and migrate instead of relying on a factory database being installed

add alert script that checks for volumes status and writes /var/tmp/alert
