The only "reason" (if you can call it that) is that Oracle seems to
push it so hard for linux. However we do have a whitepaper from
Symantec on setting up Veritas and ASM without asmlib, so we'll
probably go that route when we get a chance to redo it all.

Yes those same claims are the siren song that lured me to asmlib. As
I said, we'll probably try a setup without asmlib when we get a chance
in a few weeks. I just wondering (hoping?) that there might be a fix
for my foul-up.
