As I noticed a lot of missing information when trying to implement checking
for missing info. I reimplemented the version information script to be more
robust, and here is the result.
Follow up to ec07c3c80b
This tries to add information about when each option was added. It goes
back to version 183.
The version info is included from a separate file to allow generating it,
which would allow more control on the formatting of the final output.
The kernel default for tmpfs mounts is rwxrwxrwt, i.e. world-writable with the
sticky bit set. This makes sense for /tmp and /var/tmp, but less so for other
directories. Users will not use systemd-mount to mount /tmp and /var/tmp, so
the existing behaviour is surprising. The defaults are overriden to the
same defaults we use for "internal tmpfs mounts", i.e. no sticky bit, nosuid,
nodev, and limits of size=10%, nr_inodes=400k.
--tmpfs is new, so we can modify the behaviour without breaking compatibility.
Mount units can do it, but the command line tool cannot, as it needs a
valid 'what'. If --tmpfs/-T if passed, parse the argument as 'where'
and send a literal 'tmpfs' as the 'what' if not specified.
The documentation suggests that the mount point (i.e. the directory
where the device is mounted) is removed when the device vanishes.
However only stopping of the automount unit is implemented.
So adapt the documentation to reality.
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
No need to waste space, and uniformity is good.
$ perl -i -0pe 's|\n+<!--\s*SPDX-License-Identifier: LGPL-2.1..\s*-->|\n<!-- SPDX-License-Identifier: LGPL-2.1+ -->|gms' man/*.xml

time-out
n 1: a brief suspension of play; "each team has two time-outs left"
From The Free On-line Dictionary of Computing (18 March 2015) [foldoc]:
timeout
A period of time after which an error condition is raised if
some event has not occured. A common example is sending a
message. If the receiver does not acknowledge the message
within some preset timeout period, a transmission error is
assumed to have occured.
Docbook styles required those to be present, even though the templates that we
use did not show those names anywhere. But something changed semi-recently (I
would suspect docbook templates, but there was only a minor version bump in
recent years, and the changelog does not suggest anything related), and builds
now work without those entries. Let's drop this dead weight.
Tested with F26-F29, debian unstable.
$ perl -i -0pe 's/\s*<authorgroup>.*<.authorgroup>//gms' man/*xml
These lines are generally out-of-date, incomplete and unnecessary. With
SPDX and git repository much more accurate and fine grained information
about licensing and authorship is available, hence let's drop the
per-file copyright notice. Of course, removing copyright lines of others
is problematic, hence this commit only removes my own lines and leaves
all others untouched. It might be nicer if sooner or later those could
go away too, making git the only and accurate source of authorship
information.
This part of the copyright blurb stems from the GPL use recommendations:
https://www.gnu.org/licenses/gpl-howto.en.html
The concept appears to originate in times where version control was per
file, instead of per tree, and was a way to glue the files together.
Ultimately, we nowadays don't live in that world anymore, and this
information is entirely useless anyway, as people are very welcome to
copy these files into any projects they like, and they shouldn't have to
change bits that are part of our copyright header for that.
hence, let's just get rid of this old cruft, and shorten our codebase a
bit.
Files which are installed as-is (any .service and other unit files, .conf
files, .policy files, etc), are left as is. My assumption is that SPDX
identifiers are not yet that well known, so it's better to retain the
extended header to avoid any doubt.
I also kept any copyright lines. We can probably remove them, but it'd nice to
obtain explicit acks from all involved authors before doing that.
The kernel needs two numbers, but for the user it's most convenient to provide the
user name and have that resolved to uid and gid.
Right now the primary group of the specified user is always used. That's the most
common case anyway. In the future we can extend the --owner option to allow a group
after a colon.
[I added this before realizing that this will not be enough to be used for user
runtime directory. But this seems useful on its own, so I'm keeping this commit.]
This makes `systemd-umount` or `systemd-mount -u` support unmounting
loop devices by the corresponding backing files, like
`systemd-mount --umount /tmp/foo.img /tmp/bar.img`
Fixes#6206.
This makes systemd-umount (or systemd-mount -u) supports multiple arguments
which can be path, device, or fstab style node name, like
`systemd-umount /path/to/umount /dev/sda1 UUID=xxxxxx-xxxx LABEL=xxxxx`.
C.f. https://github.com/systemd/systemd/pull/5235#issuecomment-277731314.
The --help text currently uses the "--umount" spelling, hence to the
same in the man page too.
And let's settle on "umount" instead of "unmount" here, since most folks
probably expect that when typing in a command, as util-linux' tool is
called "umount" after all, and so is the symlink "systemd-umount" we
install.
This adds "systemd-mount" which is for transient mount and automount units what
"systemd-run" is for transient service, scope and timer units.
The tool allows establishing mounts and automounts during runtime. It is very
similar to the usual /bin/mount commands, but can pull in additional
dependenices on access (for example, it pulls in fsck automatically), an take
benefit of the automount logic.
This tool is particularly useful for mount removable file systems (such as USB
sticks), as the automount logic (together with automatic unmount-on-idle), as
well as automatic fsck on first access ensure that the removable file system
has a high chance to remain in a fully clean state even when it is unplugged
abruptly, and returns to a clean state on the next re-plug.
This is a follow-up for #2471, as it adds a simple client-side for the
transient automount logic added in that PR.
In later work it might make sense to invoke this tool automatically from udev
rules in order to implement a simpler and safer version of removable media
management á la udisks.
