As far as I've gathered, this is caused primarily by the spinup/spindown/seek/read sequence. Couldn't we have some kind of option to mount_cd9660 to disable / postpone spindown? >> I take it that nobody will object if I move it to /var/run? >Only everyone that expects it to be in /etc, along with everyones' >scripts and all the ports (eg. sshd). How about adding a /var/run/nologin, while keeping /etc/nologin for some time, to give people time to change their sources? Also, isn't there some way to create a symlink or something which doesn't show up when the target file does not exist? >You'd still get disk accesses.

Alternately, he could fix unionfs and use an MFS root w/cdrom overlay. --- Marius Bendiksen, IT-Trainee, ScanCall AS To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
