Description Alister Burrell 2005-03-24 05:12:27 UTC
I would like to see portage tellling you to man portage and see package.keywords when emerging a masked package with or without ACCEPT_KEYWORDS='~x86' and a section added after the example that says something like:

"This should be used when emerging unstable packages on a usually stable system to ensure they stay emerged and don't revert causing possible portage,glibc or gcc problems problems that will be near impossible to recover from"

I feel there are not enough warnings given about this and the documentation is spread between the web, word of mouth and this man page all of which are inadequate.

portage(5) already says something like that under package.keywords

really i dont know understand what you're trying to say
Comment 2 Jason Stubbs (RETIRED) gentoo-dev 2005-10-16 08:42:13 UTC
Agreed. Don't know what the issue is. 
Comment 3 Alister Burrell 2005-10-17 06:11:28 UTC
How about a link to it then :)

It's well known that the use of (possibly fluctuating) environment variables to
influence portage behavior can be a bad practice when the user is not quite sure
of the consequences.  Perhaps emerge should give a warning whenever it is using
variables directly from the environment (rather than make.conf) such as CFLAGS,
ACCEPT_KEYWORDS, USE, etc...
Comment 5 Jason Stubbs (RETIRED) gentoo-dev 2005-10-18 03:26:35 UTC
Or just not use environment variables at all by default? ;) 
Comment 6 Alister Burrell 2005-10-18 04:13:18 UTC
Jason,

Well you and I both know this and so do most others reading this but most the
n00bs won't.  Put yourself in the position of soemoen new to Gentoo perhaps even
new to Linux and you will see the documentation is fragmented and needs to be
all in one place or clear.  I doubt a n00b will man package.keywords.  Infact
I'm a n00b but I never did I read it online in a portage guide but not all are
going to read as much as some of us.

dropping USE_ORDER="env:bla" as the default++

If it causes trouble might as well just disable it for most users, prevent them 
from shooting themselves in the foot.  It only really requires an large warning 
telling them it doesn't work anymore.
Comment 8 Marius Mauch (RETIRED) gentoo-dev 2005-10-18 23:54:49 UTC
Lets keep USE_ORDER out of this, doesn't really help with this issue and will
probably makes things worse if people start messing with it.

That sounds reasonable to me.  For example, a special --env-override option
could be added to allow experienced users to have something like the original
behavior when necessary.
Comment 10 Jason Stubbs (RETIRED) gentoo-dev 2005-10-19 04:20:58 UTC
USE_ORDER was actually what I was referring to.. Although after a quick look 
it appears that USE_ORDER (surprisingly enough) only applies to USE anyway. 
 
So what is actually wanted here? Would just modifying "Please note that all 
user settings should be made in  the  environment  or  in  /etc/make.conf, 
which is intended to be customized by the user." by removing the environment 
remark be enough? Perhaps adding a note afterward that configuration done via 
the environment is not persistent?
