Yes, I think LVM is not quite at the stage yet where it is 100% robust
against crashes or errors during configuration changes.

I don't know why you would want swap and /var as regular partitions.
Unless you have an incredibly small amount of RAM (i.e. 8MB or less)
you don't really need swap for booting.  Likewise, you don't need /var
right at boot time either.

In fact, on my 128MB laptop I don't use any swap at all, ever.  I first
turned it off when there were problems in the 2.4.x kernels with systems
going into livelock trying to flush swap pages, and never turned it on
again.  The only time I have memory problems is when I run silly filesystem
benchmarks that use 100k inodes, and the 2.4.5 kernel still doesn't flush
the inode slab cache properly.

Cheers, Andreas
