- Do a dummy ls to workaround a FreeBSD (or NanoBSD) bug.
 - Fix sed script so / would work without problem (it's weird why this is
   implemented in sed by the way)

Make this work on vanilla FreeBSD.

The old code would break looking for FreeNAS specific files
specifically /etc/rc.freenas which would immediately crash
the script, it would then later hang when there was no
/etc/version which would then cause "cat <no args>" to
be part of a pipeline which would deadlock.

With this fixed you can run freenas-debug on build.ix
and develop it outside of FreeNAS/TrueNAS.
add additional userland tools for debugging
