[arch-dev-public] new mount in testing

[Tom Gundersen]

Hi guys,

With util-linux-2.21 we have switched to a new implementation of
mount, based on the libmount library. We have tested this in the
release candidates for some weeks, and it seems good to go.

However, I intend to keep util-linux in testing longer than normal
just in case. Please keep an eye out for oddities, especially if you
are using mount in any non-standard ways that we might not have
tested.

Cheers,

Tom
