Kernel 2.6 with LVM2 (RHEL4) is very different than Kernel 2.4 with LVM
(RHEL3).  The device-mapper (DM) facilities provide snapshots, as well
as software RAID-1 mirroring (instead of MD, which is also an option),
resizing, etc...

Last time I checked, most of the LVM2/DM tools were getting there, as
long as you didn't do more than one operation at a time (e.g., snapshot
of a LVM2 RAID-1 mirror).  If you did, that created a race condition.

I haven't messed with LVM2/DM since late last fall as a result.

It is mathematically impossible for someone who makes more than you
to be anything but richer than you.  Any tax rate that penalizes them
will also penalize you similarly (to those below you, and then below
them).  This is why someone who makes more than you always gets at
least the same, if not a bigger, tax cut.  Otherwise is impossible.
