Everything looks good to me except the overlay instructions. The
suggestion to copy the overlay eclass on top of the portage one is a
little dubious. Can you sync afterwards?

You also mention adding the overlay and "make sure you set up your
repos.conf." I'm just not sure what you mean there, I've never used
repos.conf for anything. What am I supposed to do with it?

Unrelated: would it make sense at some point to set USE=xattr in the
profile if this is the way forward?

Oh and I think USE="ptpax xtpax" is redundant now, but you probably know
that.

I agree. I'll drop that suggestion. Its what I did for quick testing
but not appropriate for long term. It would not survive a sync.

In /etc/portage/repos.conf you should add

[DEFAULT]
class-overrides = hardened-dev

This causes the eclass from the overlay to override the default eclass
from the portage tree. man portage and you'll see. I'll add a blurb
about it in the howto.

Good point. I'll look into making it part of the profiles for all
hardened systems.

It is and it isn't. I have IUSE="+ptpax +xtpax" in the ebuild. What I
wanted to say here was "don't turn off either because we'll need both
for the migration". I think I'll take out the USE="ptpax xtpax" and
just and an English sentence warning not to turn of either.

Thanks for the feedback!

Ah, I see. Otherwise the hardened-dev ebuilds would use the hardened-dev
eclass, but ebuilds from other repos would use their own copy (or the
default copy).

I'm not sure this is still the case, somewhere in the internet is
written that now priority is given from the order of appareance in the
$PORTDIR_OVERLAY.
with the leftmost being the lowest priority and the rightmost the higher
priority.
Cannot give much more explanation, maybe portage guys can (including
history hopefully)

You know, I haven't jumped into the code, but I've notice some "strange"
behavior with respect to stacking of overlays and eclasses. I
personally think overlays are not a good idea anyhow and are okay just
for testing and play.
