I know how. It is just fairly difficult to do in this case. The machine has 1Gb of RAM and a total of 4Gb of virtual memory. I was hoping, it would be easy to reproduce, but if you insist, I'll look around for the dump-device, that is big enough. = > May be, someone will address the naming problem in devfs too :) = > = > Ultimately, I'd like to be able to mount devfs as /dev, so I can = > mount the / as read-only. = Uhm, you need to be much more specific here... Well, it seems, that the only thing, that prevents me from having a read-only / is the stuff in /dev. For example, sshd will want to chown the tty to me when I login an close the session if it can not. If I could mount the devfs' /devs over /dev, I could mount the / read only... I think, that is... This is an "appliance" like setup, and changes to the / are not anticipated (/var/log and /tmp are separate partitions, no e-mail, no news). Keeping / mount to will, hopefully, decrease the danger of it getting corrupted by power outages and bugs. -mi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
