Well, it should be doable. I have something similar in spirt -- pxe booted (network booted that is, if you dont know pxe) boxes that get their entire OS from a nfs mount that is read-only. Fairly early in the boot, I have some rc stuff that does mount_mfs for /var and /tmp so I have some scratch space that I can write to for this specialized application. At any rate, its not too hard to make bootable cds these days so you could boot an image that mount_mfses critical sections and copies things in that you need... Or you could even boot of an MD image stored on a slice on a CD... eitehr way. When you figure it out and get it working, make a web page giving the step-by-step guide to how to do it... :) Fred -- Fred Clift - fclift@verio.net -- Remember: If brute force doesn't work, you're just not using enough.
