Re: Linux Equivilant of Ghost?

[Stephen Samuel <samnospam@bcgreen.com>]

You can also do the process the other way 'round.
 From the machine doing the install:

shh pickup@sourcebox  dd if=/hold/rootimage  bs=40K | dd of=/dev/hda1 bs=40k

You really want to make sure that the partition used to create
rootimage is smaller than the partition on any of your destination
machines.  Once you've DD'd the data over, then
    resize2fs /dev/hda1
(presuming that you're using ext[23]fs for the OS. Other Filesystems
may have their own utility) resize2fs will expand an ext2 or ext3 fs to
fit whatever partition it is currently in.
