5f129649b9 nspawn,machined: change default container image location from /var/lib/container to /var/lib/machines
Given that this is also the place to store raw disk images which are
very much bootable with qemu/kvm it sounds like a misnomer to call the
directory "container". Hence, let's change this sooner rather than
later, and use the generic name, in particular since we otherwise try to
use the generic "machine" preferably over the more specific "container"
or "vm".

0dfaa00607 nspawn: add "-n" shortcut for "--network-veth"
Now that networkd's IP masquerading support means that running
containers with "--network-veth" will provide network access out of the
box for the container, let's add a shortcut "-n" for it, to make it
easily accessible.

b9ba4dabba nspawn: when booting in ephemeral mode, append random token to machine name
Also, when booting up an ephemeral container of / use the system
hostname as default machine name.

This way specifiyng -M is unnecessary when booting up an ephemeral
container, while allowing any number of ephemeral containers to run from
the same tree.

ec16945ebf nspawn: beef up nspawn with some btrfs magic
This adds --template= to duplicate an OS tree as btrfs snpashot and run
it

This also adds --ephemeral or -x to create a snapshot of an OS tree and
boot that, removing it after exit.

574edc9006 nspawn: Add try-{host,guest} journal link modes
--link-journal={host,guest} fail if the host does not have persistent
journalling enabled and /var/log/journal/ does not exist. Even worse, as there
is no stdout/err any more, there is no error message to point that out.

Introduce two new modes "try-host" and "try-guest" which don't fail in this
case, and instead just silently skip the guest journal setup.

Change -j to mean "try-guest" instead of "guest", and fix the wrong --help
output for it (it said "host" before).

Change systemd-nspawn@.service.in to use "try-guest" so that this unit works
with both persistent and non-persistent journals on the host without failing.

5aded36978 man: add a mapping for external manpages
It is annoying when we have dead links on fd.o.

Add project='man-pages|die-net|archlinux' to <citerefentry>-ies.

In generated html, add external links to
http://man7.org/linux/man-pages/man, http://linux.die.net/man/,
https://www.archlinux.org/.

By default, pages in sections 2 and 4 go to man7, since Michael
Kerrisk is the autorative source on kernel related stuff.

The rest of links goes to linux.die.net, because they have the
manpages.

Except for the pacman stuff, since it seems to be only available from
archlinux.org.

Poor gummiboot gets no link, because gummitboot(8) ain't to be found
on the net. According to common wisdom, that would mean that it does
not exist. But I have seen Kay using it, so I know it does, and
deserves to be found. Can somebody be nice and put it up somewhere?

5ae4d543cb os-release: define /usr/lib/os-release as fallback for /etc/os-release
The file should have been in /usr/lib/ in the first place, since it
describes the OS container in /usr (and not the configuration in /etc),
hence, let's support os-release files in /usr/lib as fallback if no
version in /etc exists, following the usual override logic.

A prior commit already enabled tmpfiles to create /etc/os-release as a
symlink to /usr/lib/os-release should it be missing, thus providing nice
compatibility with applications only checking in /etc.

While it's probably a good idea if all apps check both locations via a
fallback logic, it is only necessary in the early boot process, as long
as the /etc/os-release symlink has not been restored, in case we boot
with an empty /etc.

ab046dde6f nspawn: add new --network-bridge= switch
This adds the host side of the veth link to the given bridge.

Also refactor the creation of the veth interfaces a bit to set it up
from the host rather than the container. This simplifies the addition
to the bridge, but otherwise the behavior is unchanged.

82adf6af7c nspawn,man: use a common vocabulary when referring to selinux security contexts
Let's always call the security labels the same way:

  SMACK: "Smack Label"
  SELINUX: "SELinux Security Context"

And the low-level encapsulation is called "seclabel". Now let's hope we
stick to this vocabulary in future, too, and don't mix "label"s and
"security contexts" and so on wildly.

- Break --help text at 80 chars

a8828ed938 Add SELinux support to systemd-nspawn
This patch adds to new options:

-Z PROCESS_LABEL

This specifies the process label to run on processes run within the container.

-L FILE_LABEL

The file label to assign to memory file systems created within the container.

For example if you wanted to wrap an container with SELinux sandbox labels, you could execute a command line the following

chcon system_u:object_r:svirt_sandbox_file_t:s0:c0,c1 -R /srv/container
systemd-nspawn -L system_u:object_r:svirt_sandbox_file_t:s0:c0,c1 -Z system_u:system_r:svirt_lxc_net_t:s0:c0,c1 -D /srv/container /bin/sh

This is a recurring submission and includes corrections to various
issue spotted. I guess I can just skip over reporting ubiquitous

Highligts in this particular commit:
- the "unsigned" type qualifier is completed to form a full type
  "unsigned int"
- alphabetic -> lexicographic (that way we automatically define how
  numbers get sorted)
