man: use same header for all files The "include" files had type "book" for some raeason. I don't think this is meaningful. Let's just use the same everywhere. $ perl -i -0pe 's^..DOCTYPE (book|refentry) PUBLIC "-//OASIS//DTD DocBook XML V4.[25]//EN"\s+"http^<!DOCTYPE refentry PUBLIC "-//OASIS//DTD DocBook XML V4.5//EN"\n "http^gms' man/*.xml

man: revert dynamic paths for split-usr setups This did not really work out as we had hoped. Trying to do this upstream introduced several problems that probably makes it better suited as a downstream patch after all. At any rate, it is not releaseable in the current state, so we at least need to revert this before the release. * by adjusting the path to binaries, but not do the same thing to the search path we end up with inconsistent man-pages. Adjusting the search path too would be quite messy, and it is not at all obvious that this is worth the effort, but at any rate it would have to be done before we could ship this. * this means that distributed man-pages does not make sense as they depend on config options, and for better or worse we are still distributing man pages, so that is something that definitely needs sorting out before we could ship with this patch. * we have long held that split-usr is only minimally supported in order to boot, and something we hope will eventually go away. So before we start adding even more magic/effort in order to make this work nicely, we should probably question if it makes sense at all.

cgls: add --unit to show units $ systemd-cgls -u systemd-journald.service machine.slice I opted for a "global" switch, instead of modifying the behaviour of just one argument. It seem to be a more useful setting, since usually one will want to query one or more units, and not mix unit names with paths. Closes #5156.

<title>Description</title>
<para><command>systemd-cgls</command> recursively shows the
contents of the selected Linux control group hierarchy in a tree.
If arguments are specified, shows all member processes of the
specified control groups plus all their subgroups and their
members. The control groups may either be specified by their full
file paths or are assumed in the systemd control group hierarchy.
If no argument is specified and the current working directory is
beneath the control group mount point
<filename>/sys/fs/cgroup</filename>, shows the contents of the
control group the working directory refers to. Otherwise, the full
systemd control group hierarchy is shown.</para>
