[gentoo-dev] New global USE flags "upower and "udisks" (split from "udev" in some cases)

[gentoo-dev] New global USE flags "upower and "udisks" (split from "udev" in some cases)

[Samuli Suominen]

Some history first:

When sys-fs/udisks and sys-power/upower was introduced to Portage, they
only had handful of consumers,
and there was no sys-apps/systemd in Portage
They were non problematic packages and could be considered as wrappers
that linked desktops to udev -related
functionality
But, now, upower upstream writes code only with systemd in mind, dropped
hibernate/suspend without any
consideration to non-systemd users
And, Portage doesn't understand || ( ) dependencies anymore wrt
http://bugs.gentoo.org/show_bug.cgi?id=515230
And, people started using local USE flags "udisks" and "upower" despite
being advised against it
And, more people are requesting sys-fs/udisks and sys-power/upower to be
moved away from USE="udev" to
these 2 separate flags, like http://bugs.gentoo.org/show_bug.cgi?id=516380
These 2 flags are already enabled by default in the desktop profile
target, just like USE="udev" is

So, I propose:

upower with short generic description of "Support for power management"
udisks with short generic description of "Support for storage management"

These packages use them already, but a lot more will follow:

Being a proxy maint of lc-vrooby, I support this proposal.

Also, have you considered udisks2? For example, lc-vrooby can use any
of udisks:0 and udisks:2, but the rdeps that get pulled and the
backends that get compiled are controlled by the flags.

There should be no separate USE flags for udisks:0 and udisks:2. They can
be installed *and* ran at the same time.
If both are supported, and it's a compile time option, :2 should be forced
If both are supported, and they can be automatically detected at
runtime, || ( sys-fs/udisks:2 sys-fs/udisks:0 ) syntax
should be used
We have a Tracker open for migrating to udisks:2 and adding udisks:0
support is a bug (regression)
