When building distribution packages without building an image, the
distribution packages will only be located in mkosi.builddir/ now and
not in mkosi.output/, so update the documentation to reflect that.
Also add installation instructions for distributions other than CentOS/Fedora
while we're at it.
Not all possible DNS names will survive serialization. Restrict the set
of valid dns names to LDH encoded names.

Currently every progress update results in a new progress message
which is extremely verbose. Instead, let's use the progress bar infra
to draw a proper progress bar similar to what we do in systemd-repart
now.
This generates the Windows Terminal OSC sequences indicating progress.
This let's the terminal know that we are doing a slow operation, and how
we are progressing.
Windows Terminal uses this in two ways: it shows a circle in the tab
that completes, and it highlights the progress in the task bar.
I found no Linux terminal that currently supports it, but also none that
didn't like it. Thankfully most terminals correctly ignore unrecognized
OSC sequences.
I think we should just merge this, and see if this trips up too many
people, but I have reason to believe this shouldn't be too bad.
And yes, I do work from Windows Terminal sometimes, ssh into my Linux
build systems, and it is really cute seeing the progress animation
there.
Let's ramp up security for system user accounts, at least where
possible, by creating them fully locked (instead of just with an invalid
password). This matters when taking non-password (i.e. SSH) logins into
account.
Fixes: #13522
* e42eed4afd test_sysusers_defined: support new ! line flag for creating fully locked accounts
* 2c6a4e2f90 Version 256.7
* bedc0270e7 Move yum/dnf protection removal config file under /usr
* 5a82129a41 Reword some descriptions
* ce99022f7b Version 256.6
We should avoid unnecessary abbreviations for such messages, and this
puts a maximum limit on things, hence it should indicate this in the
name.
Moreover, matches is a bit confusing, since most people will probably
call "busctl monitor" without any match specification, i.e. zero
matches, but that's not what was meant here at all.
Also, add a brief switch for this (-N) since I figure in particular
"-N1" might be a frequent operation people might want to use.

The --timeout= logic was implemented incorrectly, as it would not put a
a limit on the runtime of the operation, but only on the IO sleep.
However, spurious wakeups are possible, hence the timer would be reset
too often.
Fix that, by determining the absolute timestamp early, and checking
against that.

We are going to output a series of JSON objects, hence let's
automatically enable JSON-SEQ output mode, as we usually do.
"jq --seq" supports this natively, hence this should not really restrict
us.

Now that we have the mkosi.clangd script to run clangd from the mkosi
build script, it becomes clear that doing cleanup with mkosi.clean has
a big gap in that we always run the mkosi.clean script and thus we also
run it when we run the mkosi.clangd script, causing the previously built
packages to be removed when we run clangd without producing new ones.
In mkosi we're improving the situation by only running clean scripts when we
clean up the output directory and disallowing writing to the output directory
from build scripts.
Let's adapt systemd to these changes by moving the copying of packages to the
output directory to the postinst script.
Before a339495b1d, update-utmp typically
connects the public DBus socket when disconnected from the private DBus
socket, as dbus service should be active even during PID1 is being reexecuted.
However, after a339495b1d, update-utmp
tries to connect only the private DBus socket, but reexecution of PID1
may be slow, hence all trials may fail when the reexecution is slow.
With this change, now it waits for 100ms to 2000ms, so in total it waits
about 37 seconds in average, previously about 4 seconds.
This applies the existing SocketUser=/SocketGroup= options to units
defining a POSIX message queue, bringing them in line with UNIX
sockets and FIFOs. They are set on the file descriptor rather than
a file system path because the /dev/mqueue path interface is an
optional mount unit.
This commit adds two settings private and strict to
the ProtectControlGroups= property. Private will unshare the cgroup
namespace and mount a read-write private cgroup2 filesystem at /sys/fs/cgroup.
Strict does the same except the mount is read-only. Since the unit is
running in a cgroup namespace, the new root of /sys/fs/cgroup is the unit's
own cgroup.
We also add a new dbus property ProtectControlGroupsEx which accepts strings
instead of boolean. This will allow users to use private/strict via dbus
and systemd-run in addition to service files.
Note private and strict fall back to no and yes respectively if the kernel
doesn't support cgroup2 or system is not using unified hierarchy.
Fixes: #34634
This commit refactors ProtectControlGroups= from using a boolean
in the dbus/execute backend to using an enum. There is no functional
change but this will allow adding new non-boolean values (e.g. strict,
private) a la PrivateHome.
We often used a pattern like if (!FLAGS_SET(flags, SD_JSON_FORMAT_OFF)),
which is rather verbose and also contains a double negative, which we try
to avoid. Add a little helper to avoid an explicit bit check.
This change clarifies an aditional thing: in some cases we treated
SD_JSON_FORMAT_OFF as a flag (flags & SD_JSON_FORMAT_OFF), while in other cases
we treated it as an independent enum value (flags == SD_JSON_FORMAT_OFF).
In the first form, flags like SD_JSON_FORMAT_SSE do _not_ turn the json
output on, while in the second form they do. Let's use the first form
everywhere.
No functional change intended.
Initially I wasn't sure if this helper should be made public or just internal,
but it seems such a common pattern that if we expose the flags, we might just
as well expose it too, to make life easier for any consumers.
We would need to use pure if the funtion was getting pointers and
dereferencing them. But sd128_t is a structure and those functions
only access the parameters of the call.
A colleague reported when RootDirectory= does not exist, systemd reports an error like:
```
Failed to set up mount namespacing: No such file or directory
```
Unfortunately, with large spec files, it can be hard to diagnose which path systemd is talking
about. Thus, to make the error message more helpful and similar to mount error messages, we add
the root directory/image path into the error message like:
```
Failed to set up mount namespacing: /tmp/thisdoesnotexist: No such file or directory
```
