Hi guys,

A new and very exciting release of util-linux is imminent. Even though
we only have an -rc1 so far, I thought it might be worthwhile to put
it out there so people can try it out (in case we want anything fixed
before the final release):


I enabled libmount support in mount, but this will probably be
reverted before the final release unless we have good reason to
believe it to be safe.

Major changes:

- agetty gets most of the features from mingetty.
- dmesg gets lots of new filtering capabilities
- mountpoint moves here from sysvinit (we probably have to manually
remove it from the sysvinit package).

We still patch hwclock to move the adjustment file from /etc to /var.
I'm not a big fan of this, and hope to have a backwards compatible
patch to sort things out before 2.21 is released.
