[gentoo-catalyst] catalyst aborts, can not unmount /dev

Hi,

Catalyst emerges everything then aborts with the following message:

 * Processed 94 info files.

Running lsof at the time of it trying to unmount it's bind mounted
/dev shows this:

/var/tmp/catalyst/tmp/default/livecd-stage1-x86-2006.0/dev/null

The process "15073" quoted above is this:
$ ps ax | grep 15073
15073 ?        S<s    0:00 /sbin/udevd --daemon


Anyone have any ideas why it's failing?

Thanks,

Marko
