update:

I unmerged and remerged genkernel last night and built a new kernel with
reiser compiled in - it seems I was mistaken as to what can be a module
and what can't be. At least this kernel boots now, with some minor
issues that I can sort out later. I must have forgotten to emerge lvm2
onto the real system as I can't get to the lvm partitions and looking
for vg* under ubuntu shows no such file... silly me.

I now have a question about genkernel - I've always had mixed results
with this. The docs and man pages aren't really clear about how it gets
it's .config - it looks like the first time it's run it finds a
standard .config in /usr/share/genkernel, copies that
to /usr/src/linux/.config then runs make. Afterwards the .config gets
saved in /etc/kernels for later re-use. Next time it's run it has to
detect which version to use - does it look at what /usr/src/linux points
to for this?

And the --oldconfig option is confusing also. Normally "make oldconfig"
uses a prior .config and prompts on the console for any options marked
as NEW in the new source tree. But genkernel --oldconfig seems to do
something else altogether. Can someone clear up these points?
