I would prefer existing defined common keywords.

since upstart mountall there is "nobootwait". Debian's linux-utils & libs is again too old not supporting it - meaning manual "mount /media/tv" run will throw error so "mount -s /media/tv" would be needed but it is supported by upstart processes.

actual devel xbian-update is putting it already to /home, /lib/modules and / - this makes no need to commend them out in case of booting from non-btrfs filesystem.
