I'm running FBSD 2.2.7-stable. For various reasons I'd like to be able to upgrade fbsd machines without having to be seated in front of them. Specifically, I want to reboot into a mode where only a minimal amount of system activity is occurring, regular users are excluded, but remote root access and nfs mounts are allowed. This would allow me to login, mount a remote /usr/src & /usr/obj, run "make installworld" and install a new kernel. But this seems to be problematic. I can do it at the console by rebooting singleuser and running fsck, swapon, ifconfig and mount, but I have problems when I try to do it with a modified /etc/rc. Specifically, in /etc/rc I check for the existence of the file /etc/netmaintboot immediately after the network_pass1 call. If the file exists I execute /etc/rc.netmaint and exit 0. /etc/rc.netmaint consists of:

#!/bin/sh # boot configured for maintenance from network ldconfig /usr/lib echo "Down for maintenance, try again later" > /etc/nologin TERM=cons25 clear echo "Entering maintenance mode, please don't touch" /sbin/sshd -b 1024 & exit 0

But for some reason sshd dies immediately and I can't login. But if I then login at the console and run sshd manually it works fine.

Any ideas?? Do you think this kind of capability should be incorporated into a future release?

Thanks!! Rich
