# The normal set of Linux devices is too big for embedded use
# (takes too many inodes for small filesystems).
# This script makes an adequate subset for most purposes.

# This script has to be run as root, and has therefore been 
# kept short and legible, so security concious people can
# read it and confirm that it only does what it should.
