I run a headless ubuntu server from a usb drive, and to minimize writes I want to move the /var folder to a different drive.
The problem is that all other drives are encrypted, and become avaliable only well after boot is finished. I could of course just
mount /dev/mapped/drive /var but then I'm sure a lot of processes will get confused as to why their old open file descriptors cant speak to their newly created ones.
Is there a way to basically restart the whole system without having to reboot or do I have to try to figure out which processes are running and /etc/init.d/* restart them manually?
