- Extra memory because ASAN needs it
- The environment variables to make the sanitizers more useful
- LD_PRELOAD because the ASAN DSO needs to be the first in the list
- The sanitizer library packages
- Disable syscall filters because they interfere with ASAN
- Disable systemd-hwdb-update because it's super slow when systemd-hwdb
is built with sanitizers
- Take the value for meson's b_sanitize option from the SANITIZERS
environment variable
This imports credentials also via SMBIOS' "OEM vendor string" section,
similar to the existing import logic from fw_cfg.
Functionality-wise this is very similar to the existing fw_cfg logic,
both of which are easily settable on the qemu command line.
Pros and cons of each:
SMBIOS OEM vendor strings:
- pro: fast, because memory mapped
- pro: somewhat VMM independent, at least in theory
- pro: qemu upstream sees this as the future
- pro: no additional kernel module needed
- con: strings only, thus binary data is base64 encoded
fw_cfg:
- pro: has been supported for longer in qemu
- pro: supports binary data
- con: slow, because IO port based
- con: only qemu
- con: requires qemu_fw_cfg.ko kernel module
- con: qemu upstream sees this as legacy
The "Networking" section has a lonely single document listed right now,
even though the "Concepts" section has two more network related docs.
Move them over, let's end this loneliness.
A few related changes: be explicit that 'main' is the branch we're referring
to. There was a case recently of somebody rebasing on 'master' by mistake.
It's better to be explicit, since 'main' is still not the default for git
(AFAIK).
Also, github seems to send mails about force-pushes, so drop that as a
justification. Commenting about changes that were done is useful even if
github were to send a notification.
And finally, $subject. We do that ourselves, but outside contributors might not
know that that's expected.
The documentations dark-mode background color as
added in #23417 was perceived to be too purple-y [1]
and is therefore replaced by a desaturated black
that is derived from the systemd brand-black using
12% less HSL saturation.

I reordered the component list to match chronological order: we first install
an entry, then boot it, then the checks happen, etc. Before it was
ordered by "importance", but that is harder to follow.
The boot-counting file-renaming entry-sorting part that the boot
loader implements is moved to the main document. The second document
describes a specific implementation that is provided through systemd
units.
The sorting algorithm is extended to say that bad entries should
be sorted later.
I also added a note that bad entries should be available for booting.
For some reason, the second document said that it applies only to EFI systems.
AFAIK there are no implementations for non-EFI, but the specification should
work just fine, if somebody were to implement it. So that part is dropped.
Fixes#23345.
Sadly, bootctl doesn't implement sorting of boot entries with counting :((((
But I'm leaving that for another PR.
