[gentoo-dev-announce] New libudev and libgudev virtual

[Samuli Suominen <ssuominen@gentoo.org>]

I sent this mail earlier, but it was denied because of:

That is why you are reading this only now.

To the point:

There was a need for two new virtuals since udev has two libraries, each
with their own SONAMEs.
This is to get the benefits of automatic rebuilds to fix the breakage we
saw with libudev.so.0 going away a while ago.

You can now use:

virtual/udev (without :=, no libraries)
virtual/libgudev:= (with :=, for SONAME of libgudev-1.0.so.x)
virtual/libudev:= (with :=, for SONAME of libudev.so.x)

We have opened a Tracker bug 506034 [1] but this conversion is not time
critical, and the virtuals haven't stabilized yet, plus we wanted to fix
some (most) of the reverse deps on our own first before bothering with
the bugs, as it's usually more time consuming to file bugs than just fix them

In case you receive such an bug at later date, and you don't want to be
bothered about the change, just say so on the bug and the bug will be fixed for you.
But it's really straighforward, if your package uses one of the libs,
depend on the matching virtual, with the := in the end, otherwise it's virtual/udev
you want, without any := since it's not for libraries.
