>Description:
The attached patch makes /etc/ and /var/ writable via /etc/rc.initdiskless which allows me to use /etc and /var as volatile filesystems [until reboot], accomplishing some of the following basic tasks:
- Starting the hostid service (needed for doing things with ZFS).
- Starting sshd (otherwise it can't write out keys to /etc/ssh/ .
- Setting passwords / adding custom users.
- Start dhclient (dhclient requires write access to /etc/resolv.conf and /var/run/{interface}.leases
Etc.
