Mounting possibly defective file systems is not a good idea. If it's
possible, boot into SUM via boot -s first, check partitions (unmounted!)
and then mount -a. Use "exit" to bring up MUM afterwards.

Setting background_fsck="NO" in /etc/rc.conf may increase boot time
if problems occur, but can be useful to first check for errors, and
then bring up the system, instead of bringing up the system with maybe
problems on the partitions. I think this delay is something you can
affort.

It's not good to fsck a mounted partition anyway, because fsck can
repair minor defects on its own.

That's a good concept which I do follow myself, too. I spend some minutes
seeing fsck checking partitions after unclean shutdown, but when everything's
okay, there's no problem running into MUM *afterwards*.
