is LVM safe for RAID-1?

[Jack Howarth]

   I've been setting up software RAID-1 configurations
since Fedora Core 2 with normal partitions instead of
using LVM. I was wondering what the consensus was about
using LVM for software RAID partitions? My inclination
is that, unless one plans on adding additional drives
to the LVM partitions later, it really only adds another
layer of code that can break. Thanks in advance for
any comments.
