Previously, the man page suggested to only use nspawn for testing,
building, and debugging things. However, it is nowadays used in
production and used as building block for rocket, hence let's just admit
that it's pretty much production ready.
Some distributions (such as Fedora) are using the VARIANT field to
indicate to select packages which of several default configurations
they should be using. For example, VARIANT=Server provides a
different default firewall configuration (blocking basically
everything but SSH and the management console) whereas
VARIANT=Workstation opens many other ports for application
compatibility.
By adding this patch to the manual pages, we can standardize on a
cross-distribution mechanism for accomplishing this.

This introduces /run/systemd/fsck.progress as a simply
AF_UNIX/SOCK_STREAM socket. If it exists and is connectable we'll
connect fsck's -c switch with it. If external programs want to get
progress data they should hence listen on this socket and will get
all they need via that socket. To get information about the connecting
fsck client they should use SO_PEERCRED.
Unless /run/systemd/fsck.progress is around and connectable this change
reverts back to v219 behaviour where we'd forward fsck output to
/dev/console on our own.
Not that all functionality has been ported over to logind, the old
implementation can be removed. There goes one of the oldest parts of
the systemd code base.
The original idea of systemd.pc was to contain arch-independent system
and systemd information. By exposing libdir as part of the fields (added
in eb39a6239c), it started to carry
arch-dependent data, thus breaking multilib systems. It was then moved
to pkgconfiglibdir to deal with this (in
aec432c613), but actually the right
approach is to simply not include libdir in the .pc file at all.
THis patch hence more or less reverts both commits again, and moves the
.pc file back into pkgconfigdatadir.
As alternative for querying the systems primary libdir there's now
"systemd-path system-library-arch", hence a more correct alternative
exists for querying this variable from the .pc file.
Add UDPCheckSum option to enable transmitting UDP checksums when doing
VXLAN/IPv4. Add UDP6ZeroChecksumRx, and UDP6ZeroChecksumTx
options to enable sending zero checksums and receiving zero
checksums in VXLAN/IPv6

Generally, we will not follow symlinks, except for "w".
Avoid documentation for now for fifo, device node, directory lines,
which currently follow symlinks but better shouldn't.
"the name it is" is clumsy english, and since the most recently referred
to thing was a name anyway we can just leave the "it is".
This matches later uses in the same document.
systemd-timesyncd not only does NTP, but also manages clock monotonicity
using a flags file. In future, it might learn PTP support. Hence don't
expose its enablement state as "NTP" but use the more generic term
"network time synchronization". After all, for similar reasons
systemd-timesyncd is not called systemd-ntpd.
