Please share your comments/questions on the proposed news item below.
There is no immediate action required for most users, but it seems
like a significant enough change to warrant a broadcast.

Title: systemd rootprefix migration
Author: Mike Gilbert <floppym@gentoo.org>
Posted: 2017-07-14
Revision: 1
News-Item-Format: 2.0
Display-If-Installed: >=sys-apps/systemd-234

Starting with the 234 release, Gentoo's sys-apps/systemd package will
be built with rootprefix=/. This means most of the included programs
and system units will be installed under /lib/systemd instead of
/usr/lib/systemd.

This change brings Gentoo into alignment with most other distros which
still maintain a distiction between boot-critical programs in /, and
less critical programs in /usr. This also means that users with a
separate /usr filesystem will have an easier time booting if their
initramfs should become corrupt or fail.

Symlinks are provided for /usr/lib/systemd/systemd and
/usr/lib/systemd/systemd-shutdown to avoid breaking bootloader configs
and to allow the system to be shutdown/rebooted without issue.

This change will be mostly transparent to typical users. You may notice
that system units move from /usr/lib/system/system to
/lib/system/system as you upgrade/re-install packages; this is normal.
Units will function properly from both locations.

As always, if you run into problems, please report a bug.

Will these symlinks be maintained indefinitely? Would it be worth
suggesting updating cmdline's to point to the new location rather than
the symlink?

Otherwise, lgtm.

I don't see a strong reason to get rid of them, though it would be
nice to tidy up the ebuild at some point. I'll add a suggestion to
update the kernel command line.
