Well, my personal reason is so that I can burn a CDROM that boots, mounts the CDROM as root, mounts an mfs as /var, and asks some questions about the machine configuration to come up with a completely functional machine. A secondary reason is the ability to export a single system root for all NFS clients in a multiple client diskless/dataless configuration. A tertiary reason is to secure an NFS exported / against change. Other people have mentioned other reasons. Like the ability to place the majority of the OS in a ROM for an embedded system, or in a cartridge for a game machine (I know; this last assumes a port to another processor). > Instead of moving most of /etc out of /etc, how about approaching the > "problem" by trying to pick the set of files that are needed for > booting before mounting /usr. This includes any file having to do with networking in the NFS client case.
