With https://github.com/systemd/mkosi/pull/630, we can set environment
variables for the build script in mkosi. Let's modify the build script
so we can set the version-tag option via an environment variable of the
same name. The default is the empty string which causes meson to fall
back to the default behavior (git version).
This variable (a.k.a. rootlibexecdir), was exposed through the .pc file, but
not as rpm macro.
The .pc file must be located in the package that provides libraries, which
pulls in a lot of dependencies. In Fedora, the macros are split out to a
separate package so that other packages which need to refer to some systemd
path but don't otherwise require it, can only pull in the (much smaller and
dependency-less) macros package. zram-generator uses the path to specify the
location of systemd-makefs, so by using the rpm macro we'll be able to use
a much smaller buildroot.
Functions defined by us are supposed to return negative errno-style
errors on errors. laccess() is for access() what lstat() is for stat(),
but defined by us as a macro. This led to some confusion regarding error
handling.
Let's return a negative errno code just in case. This means callers can
it use either way: like access(), i.e. checking for a negative return
value + looking at errno, or like our own code, i.e. using the negative
errno code it returns.
vcs_tag() is slow. When the version-tag meson option is set,
we can use configure_file() directly to speed up incremental
builds.
Before (with version-tag set to v247):
```
‣ Running build script...
[1/418] Generating version.h with a custom command
real 0m0.521s
user 0m0.229s
sys 0m0.067s
```
After (with version-tag set to v247):
```
‣ Running build script...
ninja: no work to do.
real 0m0.094s
user 0m0.048s
sys 0m0.022s
```
This adds the ability to specify truncate:PATH for StandardOutput= and
StandardError=, similar to the existing append:PATH. The code is mostly
copied from the related append: code. Fixes#8983.
find_paths_to_edit() makes 2 calls to unit_find_paths(), one of which is
a retry client-side. ret_dropin_paths should be passed the same in
both cases.
After 85c5d313b5, if you, for example,
create a drop-in for -.slice without a corresponding -.slice file, you will
get the following:
# put some valid stuff in /etc/systemd/system/-.slice.d/override.conf
[root@image ~]# systemctl daemon-reload
[root@image ~]# systemctl edit -- -.slice
Assertion 'path' failed at src/systemctl/systemctl-edit.c:425, function
find_paths_to_edit(). Aborting.
Aborted
The aforementioned commit sets the ret_dropin_paths argument for
unit_find_paths(). Thus, unit_find_paths() returns 1 in the example above
because it finds a relevant drop-in. However find_paths_to_edit() was written
to expect 1 only if the unit file itself exists (it does not in this example).
To make this behave more like the version of `systemctl edit` prior to
this commit, add an additional check so the code enters the
"unit file not found" code branch.
If $SRCDIR is mounted into the build image (via mkosi overrides),
let's not reset the permissions fo the source tree so as to not
modify the original files on the host.
In the other error paths unit_file_find_fragment() doesn't log beyond
debug level, i.e. is of the non-logging library-like kind. Make sure
this error path is handled the same, so that the caller can log.
Added Cube Mix Plus (i18B) Rotation information.
Also Combined the sensor lines with the different Cube i7 stylus models because they use the same ACCEL_MOUNT_MATRIX
By default, systemd installs various sample configuration files
containing commented-out defaults. Systems seeking to minimize the
number of files in /etc may wish to install directories and
configuration files that have semantic effects, but not install not
commented-out sample configuration files.
Turn install-sysconfdir into a multi-valued option, with a "no-samples"
value to skip installing sample-only configuration files.
Sometimes, non-ramfs initrd root are useful. Eg, for kdump, because
initramfs is memory consuming, so mount a compressed image in earlier
initrd, chroot into it then let systemd do the rest of job is a good
solution.
But systemd doesn't recognize the initrd environment if rootfs is not a
temporary fs. This is a reasonable check, because switch-root in initrd
will wipe the whole rootfs, will be a disaster if there are any
misdetect.
So extend SYSTEMD_IN_INITRD environment variable, now it accepts boolean
value and two extra keyword, "auto" and "lenient". "auto" is same as
before, and it's the default value. "lenient" will let systemd bypass
the rootfs check.
As described in #2680, systemctl did ignore inhibitors if it is not
attached to a tty to allow scripts to ignore inhibitors automatically.
This pull request preserves this behavior but allows scripts to
explicit check inhibitors if required.
The new parameter '--check-inhibitors=yes' enables this feature.
The old parameter '-i'/'--ignore-inhibitors' was deprecated in favor
of '--check-inhibitors=no', the default behaviour can be specified
with '--check-inhibitors=auto'.
The new parameter is also described in the documentations and shell
completions found here.
/dev/vhost-net is a host accelerator for virtio net devices. It has been
long available and used, thus should be safe to all KVM users.

/dev/vhost-vsock allows to setup a guest CID and running
state (VHOST_VSOCK_SET_GUEST_CID, VHOST_VSOCK_SET_RUNNING)
All this should be legitimate and safe for KVM users.
