Strictly speaking, those are not environment variables, but they are compatible
and people think about them like this. Moving them makes them easier to find.
The original version of the test used netcat along with a standard
AF_UNIX socket, which caused issues across different netcat
implementations. The AF_UNIX socket was then replaced by a FIFO with a
simple echo, which, however, suffers from the same issue (some echo
implementations don't check if the write() was successful).
Let's revert back to the AF_UNIX socket, but replace netcat with socat,
which, hopefully, resolves the main issue.

Fixes#11600.
The code was effectively doing:
json_build(..., ({ char **_x = ((char**) ((const char*[]) {"one", "two", "three", "four", NULL })); _x; }));
but there was no guarantee that the storage for the array that _x points to
survives pass the end of the block. Essentially, STRV_MAKE cannot be used
inline inside of a block like this.
The GNU gold linker uses the section name `.rela.dyn` instead of
`.rela` for containing the relocation information. If this section
is not copied systemd-boot can crash.
Efitools started using wildcard section copies in their commit
b98d381b, and these wildcard sections are the only difference between
systemd-boot's section copy list and theirs. This patch add the
wildcard section `.rel*` to our objcopy, as it should include all
other wildcards assuming a recent GNU objcopy. Redundant arguments
for sections that would be matched by this wildcard are removed.
This patch has been tested on EDK II UEFI v2.70 Firmware on QEMU, and
Lenovo 0.5120 UEFI 2.40 Firmware on bare metal.
Fixes: #11541
It should make it easier to tweak them without having access to
SemaphoreCI itself (I'm glad I'm an admin there now but it shouldn't
be necessary to be an admin to add a couple of kludges :-)). More
importantly, changes to the settings will go through review and
be tested before they're applied globally potentially breaking
Semaphore as it happened two days ago.
I'll point Semaphore CI to these scripts once the PR is merged.
Creating a pipe with O_NONBLOCK causes both the read and the write end to
be marked as non-blocking.
The "write" end is passed to the kernel autofs module, and it does not
expect a non-blocking pipe. If it gets -EAGAIN when trying to write
(which is unlikely, but not completely impossible), it will close the
write end of the pipe, which leads to unexpected errors.
So change the code to only set O_NONBLOCK on the "read" end of the
pipe. This is the only end that systemd interacts with, so the only end
it should be configuring.
