:nit: better to add a chflags(1) option
chflags flags are a bit annoying to add but there is already
infrastructure in place from the swapcache work for the 'cache' flag
that could be reviewed to determine how best to add a new flag.
The 'cache' flag only had to be set in a higher level directory and
would get inherited by the run-time system recursively. A compression
flag could be made to work the same way. i.e. so you would only have
to set it on /usr/src and not on every single file inside /usr/src.
