I gave this version of LDM a whirl and was pleasantly surprised.  It
does boot quicker and, after configuring GDM for remote logins, I was
quickly presented with a login screen.  Sound still works, but I notice
that the USE_XFS and LOCALDEV options in the lts.conf file do not have
an effect.  Local devices aren't critical, but I need access to the XFS
server since we use IBM's iSeries Access that requires un/scalable
fonts.

Am I doing something wrong?
