Lustre discuss - May 2006 - booting a lustre system from a usb flash drive

I haven?t attempted a usb drive, but perhaps you should check out the oneSIS
project:

http://sourceforge.net/projects/onesis

It?s basically an nfs root project that will allow you to do what you?re
looking for with the local disk.

A flash drive has a finite number of writes, so you don''t want swap
and ''/var/log'', ''/var/db'',
''/var/cache'', etc. on the flash drive.  You
can handle ''/var/log'' with remote logging.  The other
partitions where
you need to write can go in a ramdisk.  Even better, put the whole OS
in ramdisk and forget about the flash drive.  See the Warewulf Linux
toolkit.

Some of us were discussing the possibility of booting off of a usb flash
drive (/, /usr, /var, swap, etc.) so the disks are left to be pure storage.
We were wondering if anyone has tried it and how did it work out? Anything
to keep in mind trying it out ourselves?
