But the userlevel tool needs fixed too. Recompiling is fine, as long as
it is easy to configure, a config file might be nice also.

I know devfsd is nice and good, but I don't use it. At this point I have
ALL my programs working without it.

How about releasing a new version of the userlevel tools. Just list it as
the required version in the Changes file. Have the new version check to
see if /dev/lvm is a directory or file. It probally isn't the best idea
to assume too much based on that fact, but it could be used as a basis for
devfs vs. traditional /dev compatibility in one executable without needing
a recompile.

We just required a modutils upgrade. No one really complained. A few
people (not many at all) cried about things breaking. But a quick pointer
to the Changes file set them straight. So yes, do this now.
