Reboot in a different partition

[emck]

I have a HD with 2 partitions on it and 2 different OS. I would like to know if it is possible to reboot remotely (with ssh) the machine so I can switch between the 2 OS?

Thanks for your help

The boot partition is controlled by the open firmware variable "boot-device". The command for manipulating open firmware is nvram - check the nvram manpage, see what the "boot-device" variable is for each volume you're interested in.

Should be doable...
