Lennart Poettering bbeeea4362 bootctl: replace --no-variables by --variables=BOOL 
I think the current behaviour of not doing EFI variables when we are run
in a container makes a ton of sense, but in some cases it's useful to
do EFI var setup even when a set of namespaces is set up for us, for
example to recover a hosed installation from a rescue disk.

While we are at it, let's remove some duplicate checks, and
systematically output information why we skip various operations.

Daan De Meyer 53628612b7 elf2efi: Add back python 3.7 compat 
The walrus operator was introduced in python 3.9 so using it
accidentally bumped the minimum python version to 3.9 from 3.7 and
bluca still cares about keeping this working on 3.8 so let's remove
the usage of the walrus operator.

Luca Boccassi 86cfbfae97 xattr: fix assert that breaks importctl (#37146) 
getxattr_at_malloc() calls getxattr_pinned_internal() with size 0 to get
the size of the xattr, and then asserts because n > 0
```
Assertion '(size_t) n <= size' failed at src/basic/xattr-util.c:107, function getxattr_pinned_internal().

Yu Watanabe 7566bbc5cb journal/kmsg: drop old kernels (<3.6) support 
The flags field was added by kernel v3.6:
https://github.com/torvalds/linux/commit/d39f3d77c9b1fe7cc33a14beb4a4849af0a4ac22

Now our baseline on the kernel is v5.4, so we can assume there exists
the flags field after the monotonic timestamp.

This also adds several short comments.

Yu Watanabe da741d9fd9 journal/kmsg: drop support old kernels (<3.5) without reading /dev/kmsg support

https://github.com/torvalds/linux/commit/e11fea92e13fb91c50bacca799a6131c81929986

Now our baseline on the kernel is v5.4. Let's assume /dev/kmsg is always
readable.

IP-over-Infiniband driver also uses dev_port.

As our baseline on the kernel is v5.4. Let's remove the fallback code.
