This avoids double compilation. Those files are tiny, so it doesn't save time,
but we avoid repeated warnings and errors, and it's generally cleaner to it
this way.
The number of commands in 'ninja -C build clean && ninja -C build' drops from
1462 to 1455 for me.
By defining rootprefix= we avoid a double slash in $systemdsystemunitdir and
other variables. This fixes a regression introduced in
1c2c7c6cb3 where the variables using rootprefix=/
would start with a double slash. This should be interpreted the same, but is
certainly ugly.
The rootprefix variable was added to systemd.pc in
1c2c7c6cb3, so there is no question of backwards
compatiblity. If people try to "override" the prefix and specify
--define-variable=rootprefix=/, they will get a double slash, which should be
OK, and is the same as --define-variable=rootprefix=/something/, which also
results in a double slash somewhere in the strings.
(This also removes support for booting into the EFI firmware setup
without logind. That's because otherwise the non-EFI fallback logind
implements can't work.)
Fixes: #9896
This behaves similar to the "boot into firmware" logic, and also allows
either direct EFI operation (which sd-boot supports and others might
support eventually too) or override through env var.
Now only two operations are left. Let's just move this into the caller,
since it should make things simpler, clearer and shorter, in particular
as there's only a single user for this.
It's a simple wrapper around boot_entries_load_config(), but determines
the ESP/XBOOTLDR paths automatically at first. Also, it looks for a path
/run/boot-loader-entries/ and loads the entries from there if it
exists. This is supposed to be a hook for other boot loaders to make our
tools aware of their own entries.
Previously, bootctl would show boot loader entries discovered by the
boot loader which couldn't found locally separately in the output.
Let's move this code into bootspec.c, and beef it up a bit. This way we
can use it later on for logind, and correctly show automatically
discovered windows/macos entries too.
find_default_boot_entry() is only used by systemctl.c, and currently
handles one log message in the caller instead of the callee. Let's
simplify that and move it over, too
This extends the reboot-to-firmware logic in logind, so that other than
EFI firmwares could be theoretically support. The scheme is like this:
if you want to support this, set the $SYSTEMD_REBOOT_TO_FIRMWARE=1 env
var for logind. If so, this will override the EFI logic, and cause a
file /run/systemd/reboot-to-firmware file to be created when
reboot-to-firmware is requested. This file has no contents, it's mere
existance indicates a reboot with reboot-to-firmware set.
The idea is that for alternative firmwares a drop-in for logind is added
that sets the env var, in combination with some code run during shutdown
that checks for the file and does the right thing.
It was already the case before commit a75211421f,
which upgraded the log to warning.
This seems an unintended side effect as the commit message doesn't mention it
and the old behavior looks more appropriate.
Let's move the shutdown binary into its own subdirectory in
src/shutdown, after all it is relatively isolated from the normal PID 1
sources, being a different binary and all.
Unfortunately it's not possible to move some of the code, since it is
shared with PID 1, that I wished we could move, but I still think it's
worth it.
This fixes bugs introduced by 29448498c7
and d838e14515.
Previously, RUN and SECLABEL keys are stored in udev_list with its unique
flag is false. If the flag is false, then udev_list is just a linked
list and new entries are always added in the last.
So, we should use OrderedHashmap instead of Hashmap.
Fixes#11368.
We'd call dns_resource_record_equal(), which calls dns_resource_key_equal()
internally, and then dns_resource_key_equal() a second time. Let's be
a bit smarter, and call dns_resource_key_equal() only once.
