[gentoo-dev] Adding USE=udev to linux profiles

[Ben Kohler]

Hello,

I'd like to propose adding USE=udev to our linux profiles (in 
profiles/default/linux/make.defaults probably).  This flag is already 
enabled on desktop profiles but it also affects quite a few packages 
used on non-desktop linux systems.

This flag provides useful functionality that most linux users will want. 
  I'm a bit surprised that we still don't have it in all linux profiles, 
but I think we've worked around this in the past by adding IUSE=+udev to 
quite a few of those packages (33 packages, 116 ebuilds, by my count).

This missing flag came to my attention again on bug 661584 where lvm2 
has IUSE=+udev but cryptsetup has only IUSE=udev, so non-desktop users 
have a bit of a mismatch between the 2 and get ugly errors on cryptsetup.

Since this flag only affects linux, I think it makes more sense to set 
it in linux profiles than to use IUSE defaults.

Any objections to this idea?

Thanks,

Ben
