I like the sound of the stick[1]; I don't have the install DVD to hand
(It's at work, I'm home); is my 4 Gbyte sandisk cruser big enough?
My Mac lappy's only got USB1, does anyone know whether the USB copy can
be made from Linux?
Copying to a real ATA disk is possible too[2], I imagine I can do that
to the xserve in target mode; can I choose which disk to boot from?
[1] but I don't think I can boot it, this is G4. It might not be quick
either, but if it doesn't keep stopping to ask stupid questions I don't
care.
[2] From Linux to a disk in a USB2 enclosure, or from the xserve by
mounting the DVD over NFS, or even target mode (I presume) by removing
all other disks.
