This makes the presence of sysinst in /usr/sbin MI (as intended) --
remember that one of the goals is for sysinst to be able to install
chroots, and installing a chroot is a sensible operation on all ports,
even those for which an installer per se might not make sense.
Currently this dummy architecture fails instead of doing anything, but
as they say, one thing at a time.
This commit only physically moves the sources - there are no other
changes, to maximize the probability that this will be treated as a
rename if we ever do manage to migrate away from CVS.
Moving sysinst has been discussed on and off for years and has two
goals: making it easier to work on sysinst, and also making sysinst
available on running systems for use installing chroots and VM images
and other such things. None of the latter is possible yet, but as they
say, one thing at a time.
Doing this now was approved in an impromptu fashion by mrg, riz,
riastradh, me, and groo.
