[TriLUG] backup up a laptop disk for replacement

[Rodent of Unusual Size]

heh.  my laptop drive is starting to whine and buzz, so
ibm is sending me a replacement.  that's cool hardwarily,
but.. what's the best path for backing the current drive
up and restoring it onto the new one?  rh 7.2, five partitions
on the drive.  i have my 7.2 cds.  i'm guessing one possibility
is to come up on the cd, do a dump 0 of each filesystem off
to another system over the network, replace the unit, fdisk
it and newfs it to get the partition structure back, and
then restore 0 the dumps back over the network.  the two parts
of that i'm unsure about are a) doing stuff over the network
from the cd boot, and b) writing the boot block on the new
drive.

is the above a workable/the best solution?  or is there a
better one?

tia..
