[gentoo-portage-dev] Can an ebuild override CONFIG_PROTECT?

[Amit Dor-Shifer]

I.E.: can an ebuild instruct that one of its deployables under /etc 
shall be "mercilessly auto-update"d?
Using /etc/make.conf/CONFIG_PROTECT_MASK for a single file seems a bit 
unnatural to me: a general-purpose file specifying a file o/w unknown 
and unrelated to it.

There are lots of ebuilds that install files in /etc/env.d/
containing CONFIG_PROTECT_MASK settings. It think that's what you want.

Thanks.
IMHO this usage of env.d should be documented in the ebuild howto, as it 
presents a useful-yet-not-trivial mechanism.

I'd document it, if:
a) I get no objection from others. Anyone?
b) I'd be referred to the proper place to document it in. There's a page 
dealing w/ |CONFIG_PROTECT_MASK at 
http://devmanual.gentoo.org/general-concepts/config-protect/index.html, 
but I doubt if that's the proper place.

It's touched upon in the User Handbook here:

http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?full=1#book_part2_chap5

It might be nice to mention it somewhere in the Developer Handbook:

http://www.gentoo.org/proj/en/devrel/handbook/handbook.xml?full=1

That's maintained by the devrel team, and you can file a bug for
them at bugs.gentoo.org.

Does emerge actually call 'env-update'? If so, where (I can't find in in 
the code)?
if not, who performs the environment update when an ebuild is emerged 
(I'm supposing env-update gets called. I didn't call it explicitly in my 
ebuild, yet still /etc/profile.env gets updated with CONFIG_PROTECT_MASK)?

Yes, emerge calls env-update automatically. But, you should call
source /etc/profile afterwards in you running shell. Also, there's
this bug which prevents new CONFIG_PROTECT* settings from taking
immediate effect:
