I would like to create a USB Flash Drive with Ubuntu Server (SMB, FTP, BFS, DHCP, NFS etc) to run my NAS system (something like FreeNAS).
I am able to get it bootable, however, I would like to keep the configurations persistent, but with minimal writes to the /tmp and other directories. (something like FreeNAS).
I would like to boot from the drive and then run my NAS using raid5, hence, I am not able to put the OS on the drives (would not like to partition them).
Can anyone point me to the right directions or have some suggestions?
