$ sudo ln -svf multi-user.target /run/systemd/generator.early/default.target
'/run/systemd/generator.early/default.target' -> 'multi-user.target'
$ sudo build/systemctl set-default --root=/ sysinit.target
Removed /etc/systemd/system/default.target.
Created symlink /etc/systemd/system/default.target → /usr/lib/systemd/system/sysinit.target.
Note: "multi-user.target" is the default unit (possibly a runtime override).
The output is not super informative, but it should be enough to point the user in
the right direction.
Fixes#3645.
In practice we are very unlikely to fail at this point, but for
consistency, we should always warn when allocation fails, and
we have free_and_strdup_warn() for this.
This regression was introduced in #14913.
The current_file variable can be NULL, as, for example, with the
following commands:
* journalctl --list-boots
* journalctl -b -1 --no-pager
Since current_file is only checked for pointer equality with f, removing
the assertion is safe here.
Giving --echo to systemd-ask-password allows to echo the user input instead
of masking it. This is useful when querying for usernames or similar.
Showing "(press TAB for no echo)" does not make sense there, so do not.
Note that pressing TAB or ESC still disables echo.
Without changing the SELinux label for private /dev of a service, it will take
a generic file system label:
system_u:object_r:tmpfs_t:s0
After this change it is the same as without `PrivateDevices=yes`:
system_u:object_r:device_t:s0
This helps writing SELinux policies, as the same rules for `/dev` will apply
despite any `PrivateDevices=yes` setting.
Proportional Integral controller-Enhanced (PIE) is a control
theoretic active queue management scheme. It is based on the
proportional integral controller but aims to control delay.

When having a service which intentionally outputs multiple equal lines,
all these messages might be inserted with the same timestamp.
journalctl has a mechanism to avoid duplicate lines, which might be in
different journal files.
This patch allows duplicate lines, if they are from the same file.
Up to now each uevent logs the following things at debug level:
- Device is queued
- Processing device
- Device processed
However when the device is queued it might still have to wait for
earlier devices to be processed before being able to start being
processed itself. When analysing logs this dependency information is
quite cruicial, so add respective debug log calls.
Add SECLABEL{selinux}="some value" cause udevadm crash
systemd-udevd[x]: Worker [x] terminated by signal 11 (SEGV)
It happens since 25de7aa7b9 (Yu Watanabe 2019-04-25 01:21:11 +0200)
when udev rules processing changed to token model. Yu forgot store
attr to SECLABEL token so fix it.
