One word: desktop. That's what they want to conquer next.

We don't want to use lvm - my manager doesn't like it, and given how much
we hit our machines, we almost don't use vm's, either - we need all CPU
cycles for some things (like heavy scientific computing).
We also pretty much don't use any drives under 1TB. The upshot is we had
custom scripts for > 500GB, which made 4 partitions - /boot (1G, to fit
with the preupgrade), swap (2G), / (497G - and we're considering
downsizing that to 250G, or maybe 150G) and the rest in another partition
for users' data and programs. The installer absolutely does *not* want to
do what we want. We want swap - 2G - as the *second* partition. But if we
use the installer, as soon as we create the third partition, of 497GB, for
/, it immediately reorders them, so that / is second.
Duh....
The result is that we get to the screen to choose the drive, and say
"custom partition"... then <alt-F2>, and use parted to make the
partitions, then go back to the GUI and just assign the mount points and
filesystem types.
And why would you *want* / to have everything? I want to be able to
install a newer o/s, or whatever, and not have to worry about all the
data, etc - I want that in a separate partition (no, don't format that,
thank you).
