The limits controlling how much disk space is used by the journal may
be configured with SystemMaxUse=, SystemKeepFree=, SystemMaxFileSize=,
RuntimeMaxUse=, RuntimeKeepFree=, RuntimeMaxFileSize= settings in
/etc/systemd/journald.conf. See journald.conf(5) for details.

Subject: Failed to generate valid unit name from path '@MOUNT_POINT@'.
Defined-By: systemd
Support: %SUPPORT_URL%
The following mount point path could not be converted into a valid .mount
unit name:
@MOUNT_POINT@
Typically this means that the path to the mount point is longer than allowed
for valid unit names.
systemd dynamically synthesizes .mount units for all mount points appearing on
the system. For that a simple escaping algorithm is applied: the absolute path
name is used, with all "/" characters replaced by "-" (the leading one is
removed). Moreover, any non-alphanumeric characters (as well as any of ":",
"-", "_", ".", "\") are replaced by "\xNN" where "NN" is the hexadecimal code
of the character. Finally, ".mount" is suffixed. The resulting string must be
under 256 characters in length to be a valid unit name. This restriction is
made in order for all unit names to also be suitable as file names. If a mount
point appears that — after escaping — is longer than this limit it cannot be
mapped to a unit. In this case systemd will refrain from synthesizing a unit
and cannot be used to manage the mount point. It will not appear in the service
manager's unit table and thus also not be torn down safely and automatically at
system shutdown.
It is generally recommended to avoid such overly long mount point paths, or —
if used anyway – manage them independently of systemd, i.e. establish them as
well as tear them down automatically at system shutdown by other software.

Subject: Special user @OFFENDING_USER@ configured, this is not safe!
Defined-By: systemd
Support: %SUPPORT_URL%
Documentation: https://systemd.io/UIDS-GIDS
The unit @UNIT@ is configured to use User=@OFFENDING_USER@.
This is not safe. The @OFFENDING_USER@ user's main purpose on Linux-based
operating systems is to be the owner of files that otherwise cannot be mapped
to any local user. It's used by the NFS client and Linux user namespacing,
among others. By running a unit's processes under the identity of this user
they might possibly get read and even write access to such files that cannot
otherwise be mapped.
It is strongly recommended to avoid running services under this user identity,
in particular on systems using NFS or running containers. Allocate a user ID
specific to this service, either statically via systemd-sysusers or dynamically
via the DynamicUser= service setting.

Subject: systemd-udev-settle.service is deprecated.
Defined-By: systemd
Support: %SUPPORT_URL%
Usage of the systemd service unit systemd-udev-settle.service is deprecated. It
inserts artificial delays into the boot process without providing the
guarantees other subsystems traditionally assumed it provides. Relying on this
service is racy, and it is generally a bug to make use of it and depend on it.
Traditionally, this service's job was to wait until all devices a system
possesses have been fully probed and initialized, delaying boot until this
phase is completed. However, today's systems and hardware generally don't work
this way anymore, hardware today may show up any time and take any time to be
probed and initialized. Thus, in the general case, it's no longer possible to
correctly delay boot until "all devices" have been processed, as it is not
clear what "all devices" means and when they have been found. This is in
particular the case if USB hardware or network-attached hardware is used.
Modern software that requires some specific hardware (such as a network device
or block device) to operate should only wait for the specific devices it needs
to show up, and otherwise operate asynchronously initializing devices as they
appear during boot and during runtime without delaying the boot process.
It is a defect of the software in question if it doesn't work this way, and
still pulls systemd-udev-settle.service into the boot process.
Please file a bug report against the following units, with a request for it to
be updated to operate in a hotplug fashion without depending on
systemd-udev-settle.service:

A System V service script @SYSVSCRIPT@ has been found on the system that lacks

unnecessary, additional synchronization points), are less robust (as SysV services
cannot properly be lifecycle tracked or automatically restarted) and less
secure (as no sandboxing restrictions can be enforced).

make sure to update the package in question to provide proper, native systemd
unit files. Contact vendor if necessary. Compatibility support for System V
services is deprecated and will be removed soon.
