I put up the next prerelease of util-linux in case someone wants to play around:
Same warnings apply as to rc1:
- mountpoint will conflict with sysvinit (I'll propose moving this
from sysvinit to util-linux when we have a final release); and
- libmount is enabled even though it will probably not be in the final version.
