I'd use connman for handling the net connection and it seems to require a writable /var/lib/connman/
No experiece at all, but I'd say that /var must be writeable too. Think of it some like the /home of the system, so you should have one per machine in the NFS server.
Just my two cents...
And /tmp. Obviously you need to remount,rw to update and you may have problems forcing it to remount,ro without a reboot. You will probably be rebooting after running pacman, most of the time though anyway. Much simpler on OpenBSD, mount -urf works well and every time and there are far less reboots required too. A grsecurity kernel can send you logs whenever a remount takes place and can't miss any like when using monit or something. A benefit over OpenBSD. -- ________________________________________________________ Why not do something good every day and install BOINC. ________________________________________________________
