embedded people often make the wrong decisions on limiting busybox functionality.

We do have some workarounds for missing options to "test" and missing dirname and
some others. But modifying the awk stuff is harder. We're working on facing it out,
since most of it now happens via "ipsec addconn --configsetup" but we're not there

The real fix for those systems is to use posix compliant,  slightly larger versions
of regex,sed,awk etc. Space gained from not having "id" or "dirname" is really meaningless.
