[linux-lvm] problem

[Daniel Wittenberg]

I didn't see any pre-built binaries, so I started down the source path,
and looks like it needs device-mapper, ok, I started working on that,
and it looks like it wants the LVM2 patches to the kernel source...does
this sound right?  Since I only want the LVM2 tools just for this fix,
does sistina build any RPM's or binaries?  I'm just short on time right
now and going to be a pain if I have start doing kernel patches and
everything else too...
