[9front] ISO 9front-8591: AVOID

[ori@eigenstate.org]

If you got this ISO, don't use it.

If you are on commit 2204634275cbb3337cfc7cc994b57f9aa4017d0d,
sysupdate BEFORE you install in /sys/src/cmd/git.

If you ran 'mk install, either restore git from the dump,
or apply the patch from the end of the email and pull
BEFORE you run sysupdate

If already updated and ran sysupdate again, reset the
commit IDs by hand:

	echo 2204634275cbb3337cfc7cc994b57f9aa4017d0d > /dist/plan9front/.git/refs/heads/front
	echo 2204634275cbb3337cfc7cc994b57f9aa4017d0d > /dist/plan9front/.git/refs/remotes/THEM/front

Then apply the patch and reinstall git.

You can apply the patch either by running:

	fix=acc504c319a4b4188479cfa602e40cb6851c0528
	hget  http://git.9front.org/plan9front/plan9front/$fix/patch | \
		@{cd / && ape/patch -p1}

Or by applying:
