distrib/common - shared files for building distribution media, initially
comprising of:
Makefile.crunch
build a crunchgen(1)ed binary from the provided lists
Makefile.image
build a tree from the provided lists, and
build an ffs file system image from that tree using makefs(8),
without requiring root privileges
parselist.awk
parse list files generating different output:
crunchgen config
mtree specfile
sh commands to populate a tree
