"located on the same disk as the ESP is located on" is hard to grok. Let's
use more natural phrasing. Also, we shouldn't say that "The first foo partition
… is mounted to …", because this doesn't explain what is happening. The
partition could be empty, and there could be other partitions with the "foo"
content, but what matters is the UUID.
We listed many of the root-partition type uuids, but not all. I think the
chances of somebody using the discoverable partition magic on an Itanium system
are fairly low at this point. So let's remove all architectures except the two
most popular consumer architectures. People building Longsoon or RISC-V images
are likely to have the online version of the Discoverable Partitions
Specifications handy anyway, and it makes the man page easier to read. It also
reduces the chances that somebody adding new entries to the table has some
select&paste mishap. We've already had this happen in the past and it's fairly
nasty bug. We don't need to expose the information in two places with manual
propagation between them.
In all other cases we have the older variant before the newer. And since we
generate some documentation tables from the header, this order is also visible
for users. Let's restore the order. This commit does
4565246911 in a slightly different fashion.
I think those constants are generally useful. It's quite easy to make a mistake
when copying things from the docs, so let's make them easy and convenient to
access.
In many places we spelled out the phrase behind "initrd" in full, but this
isn't terribly useful. In fact, no "RAM disk" is used, so emphasizing this
is just confusing to the reader. Let's just say "initrd" everywhere, people
understand what this refers to, and that it's in fact an initramfs image.
Also, s/i.e./e.g./ where appropriate.
Also, don't say "in RAM", when in fact it's virtual memory, whose pages
may or may not be loaded in page frames in RAM, and we have no control over
this.
Also, add <filename></filename> and other minor cleanups.
This documents that explicit `Before=`/`After=` dependencies can be
used to selectively override implicit ordering coming from default
dependencies. That allows for more granular control compared to the
already documented `DefaultDependencies=no` option.
The alternative approach came up in a discussion around the ordering
of `boot-complete.target`, so this also adds an explicit suggestion
in that direction to the "Automatic Boot Assessment" documentation.

Let's rework verify_fsroot_dir() around two statx() calls, which should
usually give us all information we need. Let's then add a call to the
btrfs ioctl only if the caller actually wants to know the backing block
device (which it generally only wants if it then intends to verify
partition type, and similar).
This makes things more robust on new kernels, and bypasses the btrfs
ioctls in environments where we cannot actually interpret the results
properly (since they reference btrfs devices via /dev/ paths, which we
likely cannot resolve in containers)
Fixes: #24616
There's little reason to require this, given that we can just say that
if a relative path is specified it is to be read relative to the root.
This fixes a bootctl bug introduced by
3730dc5d5b which didn't bother prefixing
paths as necessary.
The kernel PE image version can be used to detect support for this
feature, allowing us to prefer the generic code of the deprecated EFI
handover protocol.
We could try to relocate these but that is probably not needed. So far
we have not been bitten by this in the real world and kernels we boot
likely already support this anyway.
The boot params passed to the kernel only has to be one page in size
and the size of the setup header has to be calculated as it depends on
the boot protocol version supported by the kernel.
The kernel x86 boot protocol does not expect this value to be set when
using EFI handover protocol. If the stub is loaded above 4G we would
end up discarding the high bits, breaking boot.
Fixes: #24707
No functional changes, just refactoring.
Note, this also makes synthesize_change() propagate the error from
synthesize_change_one(). However, the caller of synthesize_change()
ignores the failure anyway, hence the change does not take any effect.
This works becuase TPM2_FLAGS_USE_PIN is 1 and bool is a 1 so the bits
line up as expected, however if for some reason flags change values and
for clarity check if the boolean indicates this flag and pass the flag
value.

This way we can use it directly in measure.c, and thus remove a bit of
redundant code.
OpenSSL prefers uppercasing the MD names, others don't hence let's be
lenient here.
As usual, it seems to be mostly additions and corrections. Sadly, it seems a
bit of mojibake has crept in in various places. But it's hard to correct, in
particular because it's hard to detect all cases automatically. I think we can
ignore this for now.
When I run this a few weeks ago, ma-large.txt was gutted and 20-OUI.hwdb was
siginificantly smaller. For whatever reasons, it's back to normal now.
Systemd's credential interface is not yet natively supported by all
programs yet. Hence it's often required to run scripts to massage
secrets in the way the programs expect it.
This commit allows the ExecStartPre commands to access credentials.
