yes, i was *joking*, what i meant was that lvm information for
booting is fed statically to the kernel.

linux also has _initfunc, which should free the kernel from bloat of
driver initialization code (eg kernelspace implementations of
vgscan/vgchange)

please I'd be thankful if ppl did read emails in the thread before replying
I was responding to Theo's claims, who said that if a luser extends /
over two disks he duubles the chance of failure. I was saying that lusers
has many ways of of shooting themselves in the feet.

my point is that there is no reason saying that root lvm is dangerous
and should be avoided. i have been using it for almost an year, and
i consider it as stable as root on an extended pc partition.
