Is it possible to remove the optical disk after booting from it, assuming that there's no magnetic disk at all? If so, how does NeXT manage the swap space? -- Reply to: Gregory S.

I've had to do this to repair a damaged root partition on an optical. 1) boot with the good optical to single user mode (bod -s) 2) /etc/disk -e /dev/rod0a 3) stick in the blown disk quickly (you have about 30 secs before it will page) 4) run /etc/fsck on the blown disk and fix it. This is assuming that you have very generic boot disks and the swap file is at the same place. You can't do this to a non-bootable disk. (hopefully you don't have to do this at all :-) Tom Leach Internet:leach@OCE.ORST.EDU UUCP:{tektronix, hp-pcd}!orstcs!OCE.ORST.EDU!leach ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Middle-of-the-road, man, it stanks.

You can of course eject the disk without unmounting it, intentionally or unintentionally, but this is pretty much evil and in most cases will crash the system. Don't eject your boot disk.
