Unix on CD?

[Ken Yap]

Hmm. Unix system binaries don't change that often. What if most of
/bin, /usr, /lib were put on a CD? Attach one RO optical drive to your
network of workstations. Heck, if the drives are cheap, even one per
workstation.  A cache would speed access to the most often requested
files. Maybe some scheme to allow bypassing distribution binaries with
local versions.  OS upgrade would be just a matter of sending out CDs.

Has this been done already? Or planned? Or too impractical yet/ever?
