I have a machine running Lenny with a 250GB IDE HD in it. The HD is on

I have a question about how best to divide things up in the new setup.
The current 250GB IDE HD has two partitions on it:
/dev/hda1 = linux (~80 MB)
/dev/hda2 = linux LVM (~249.92 GB)
I'm thinking to replace this IDE drive with two SATA HDs. One as small
as I can get. Say 100GB or so and make that the boot drive. And a second
HD say 500GB or so and moving the LVM over to that.
Sounds eminently reasonable to me.
Would it be better to move the LVM to a larger SATA drive and migrate
the boot drive on to a new small IDE HD?
You could do that, too.
Or reinstall fresh to the new IDE drive. Debian is great enough
that you *never must* reinstall, but it helps by clearing out old
cruft, etc.
I've even thought to set it up
to boot from a flash drive. Not sure that would be wise either.
Booting from flash and having the mechanical drives as /home and
"data" would also work.
Except... /var and /tmp. They volatile enough that flash probably
isn't the best place for them to be. You should put them on small
"mechanical" partitions.
My question is is this a 'wise' thing. If not, why not and what would be
the better approach?
Sure. lvm even has a utility to move a PV from one partition to
another (even though I've never gotten it to work).
