Check first ifup exists before using it since
this is really something only exits on some
distros an in different ways. Debian/Ubunu has
an package for this while others have it in the
initscripts package(s) , meaning the file can be
around even without the prog.

This should allow us to run 'prog' without
absolute paths. Eg:
run("/bin/foo"); -> run("foo");
However we still need absolute PATH for
checking since fexist() need full path right now.

For issue #64 we need to have /proc/mounts, or /etc/mtab but that's
usually symlinked to /proc/mounts.
