[gentoo-dev] Removal of auto-use in portage-2.0.54

[gentoo-dev] Removal of auto-use in portage-2.0.54

[Marius Mauch]

Hi,

As I said earlier, we'd like to get rid of the nasty auto-use feature, 
including the support for the USE_ORDER variable. Right now we intend 
this for 2.0.54 (might not be the final version number) unless there are 
major objections to it.

What will happen to the USE flags currently in use.defaults when this
is removed? Perhaps some of them be moved to the profiles instead?

I'm mostly concerned about the 'udev' USE flag. Some packages rely on
this to be able to function correctly on an udev enabled system.
Since udev seems to be the default choice for our default-linux
profiles, it would make sense to also set USE=udev in those profiles?

Apart from that, no objections from me - auto-use can be rather
confusing at times.

Regards,
Brix

It will turn off unless it is enabled somewhere else.

This is more of a releng/basesystem question rather than a portage question. 
Makes no difference to me as a user as I have USE="-* ..." in make.conf. ;)

Message logging will come in at the same time so it might be better to do 
something like:

portageq has_version ${ROOT} sys-fs/udev && use !udev && (
    ewarn "You have udev installed but do not the udev USE flag enabled."
    ewarn "${PN} might behave incorrectly."
)

Except with better bash style of course.. But that's just what I'd do. Once 
proper logging goes in, it'd be a good idea for policies on things like this 
to be developed.

This would be the best way to go about it, yes.

I think it should be set in default-linux.  This means it would need to
be use.mask'd on any 2.4 profiles.  The real issue here is what happens
to anyone that uses both 2.4 and 2.6 from the same profile?

Ok, I just disabled auto-use in make.globals in trunk, that means ~arch
users will see the change starting with pre4. The code is still present
so people who want to keep the feature can set USE_ORDER in make.conf
accordingly to get it back, however that probably will only be
temporary.

In the beginning, there was nothing. And God said, 'Let there be
Light.' And there was still nothing, but you could see a bit better.
