RE: reboot in single user
Hi all, I'm curious to know if there is a command to reboot into single user mode- * more importantly* if I do reboot in single user mode can I still SSH in? My box is not physically near me and I'm upgrading 5.5 to 6.2 - so it this possible- or do I need to go get the box and attach a keyboard monitor and mouse to it? Thanks Shutdown now goes into single user mode, but it will close SSH ! Better is to manually shutdown al daemons through /usr/local/etc/rc.d and /etc/rc.d to only have sshd running. If you using natd do not stop it either, because it will disconnect you. Then you can finnish the make world cycles. That is the way I do it from a remote shell, it it only failed me once. Else try on a spare machine install 5.5 and update it to 6.2 through a ssh version, then you know what to expect. Also install the main ports you have running on your remote 5.5 box and try if they still work.

well...do they understand how email systems work?
if they don,t then you can explain that it could be either end of the process
that caused the delay...or any other server in between (antispam, defangers,etc)
Anywayif you're bringing a production server down, you should schedule
downtime . If it has to fall during working hours, you can tell everyone to
get a beer @ the pub while you're it. I'm sure one hours delay wont be noticed
then ;)

How long will this take- as stopping the daemons (spamd/clamd etcc..) will cause a halt in my incoming mail? Weel it is only the make installworld and mergemaster part so I guess about a minut or 10 You can do the buildworld and buildkernel steps and let the machine do its work, Then you can install the kernel do a mergemaster -p and then shutdown all services. Then do the make installworld and mergemaster part. Also if you go from 5.5 to 6.2 you can do make delete-old it will remove files that are not part of the base in 6.2 And after that make delete-old-libs (WARNING) this can mean you will need to recompile some ports that use the old 5 libs, like bash If your shell is bash and you reboot the machine the possibility is that bash need an old 5.5 lib, so no access to your machine anymore. Well again install 5.5 on a spare machine, install the ports you have running on the remote location (or create packages from the other machine) and do the cycle on that spare machine, this way no unexpected things should happen.
