systemd-boot might be installed in /EFI/BOOT under more names than
just /EFI/BOOT/BOOTX64.efi. The prime example is shim which loads
its second stage binary from /EFI/BOOT/grubx64.efi. To accomodate
use cases where systemd-boot is installed as /EFI/BOOT/grubx64.efi,
let's always check the entire /EFI/BOOT directory for binaries that
identify as systemd-boot and list/update/remove those as well.
Let's keep this somewhat generic though and not install ourselves as
grubx64.efi since that would mean having to check for shim which is
a can of worms we probably don't want to open.
If the target mount point is an automount, checking it for writeability
without triggering it first is iffy and yields different results based
on kernel version:
~# systemd-run --wait --pipe -p ProtectSystem=yes bash -xec 'uname -r; mount -l | grep boot; test ! -w /boot'
Running as unit: run-u36.service; invocation ID: f948ff4f3c8e4bcfba364ead94bd0ad9

systemd-1 on /boot type autofs (rw,relatime,fd=43,pgrp=1,timeout=120,minproto=5,maxproto=5,direct,pipe_ino=356096)
+ test '!' -w /boot
Finished with result: exit-code
Main processes terminated with: code=exited/status=1
~# systemd-run --wait --pipe -p ProtectSystem=yes bash -xec 'uname -r; mount -l | grep boot; test ! -w /boot'
Running as unit: run-u274.service; invocation ID: ccc53ed63c3249348cf714f97a3a7026

One solution would be to use /boot/ instead of just /boot, which triggers
the automount during the check, but in that case the mount would happen
_after_ we apply the ProtectSystem= stuff, so the mount point would
be unexpectedly writable:
~# systemd-run --wait --pipe -p ProtectSystem=yes bash -xec 'uname -r; mount -l | grep boot; test ! -w /boot/ || mount -l | grep boot'
Running as unit: run-u282.service; invocation ID: 2154f6b4cbd34ddeb3e246cb7c991918
+ uname -r
6.6.7-arch1-1
+ mount -l
+ grep boot
systemd-1 on /boot type autofs (rw,relatime,fd=95,pgrp=1,timeout=120,minproto=5,maxproto=5,direct,pipe_ino=730583)
+ test '!' -w /boot/
+ mount -l
+ grep boot
systemd-1 on /boot type autofs (rw,relatime,fd=95,pgrp=1,timeout=120,minproto=5,maxproto=5,direct,pipe_ino=730583)
/dev/vda2 on /boot type vfat (rw,nosuid,nodev,noexec,relatime,nosymfollow,fmask=0077,dmask=0077,codepage=437,iocharset=ascii,shortname=mixed,utf8,errors=remount-ro)
Let's just trigger the (possible) automounts explicitly before we do any
checks to avoid all this stuff.
Also, when at it, check that ProtectSystem=yes|full correctly protects
the ESP mount as well.

Otherwise we might occasionally hit the start rate limit, as we restart
the service a bunch of times:

Users can currently pick specific versions of NIC naming, but that
does not guarantee that NIC names won't change after the kernel adds
a new sysfs attribute.
This patch allows for an allow/deny list of sysfs attributes
that could be used when composing the name.
These lists can be supplied as an hwdb entry in the form of
/etc/udev/hwdb.d/50-net-naming-allowlist.hwdb
net:naming:drvirtio_net

We already refuse the other two cursor-related options (--cursor= and
--after-cursor=) with --since=, so let's do the same with
--cursor-file=.
Closes: #20523
Regardless of whether a vc path is passed, the behavior of
systemd-vconsole-setup wasn't ideal when either the passed vc or /dev/tty1 was
in graphics mode.
When a vc in graphics mode was passed, no message was emitted despite the fact
that the font settings couldn't be applied. The previous code might have
assumed that setfont(8) would throw a warning but that's not case.
When no argument was passed, systemd-vconsole-setup was supposed to
automatically select a valid tty, init it and copy the font setting to the
remaining ttys. However if the selected virtual console was in KD_GRAPHICS mode
the initialization of the font failed not only for the selected source vc but
for all of them.
This patch enables IFNAME_VALID_ALTERNATIVE for checks guarding the
parsing of RestrictNetworkInterfaces=.
The underlying implementation for this option already supports
altnames.
