Currently, system/skeleton/etc/profile contains /bin:/sbin:/usr/bin:/usr/sbin
so I'd suggest we keep that as the default for this new option.

Whether that value makes sense or not is a different topic. I had a look
at POSIX, and they define a default value, nor suggest one. On my
machine, /etc/environment exports a PATH with:
    /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games
while /etc/login.defs sets PATH to:
    /usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games

So, I don;t really care, but if it is changed, it should be in its own
patch.

Cool thanks! Don't forget to Cc me on the resulting series, so I'm sure
not to miss it. (which does not mean you'll get a fast review, mind
you! :-/)
