battery-check: rework unit Let's rename the unit to systemd-battery-check.service. We usually want to name our own unit files like our tools they wrap, in particular if they are entirely defined by us (i.e. not just wrappers of foreign concepts) While we are at it, also hook this in from initrd.target, and order it against initrd-root-device.target so that it runs before the root device is possibly written to (i.e. mounted or fsck'ed). This is heavily inspired by @aafeijoo-suse's PR #28208, but quite different ;-) 2023-06-30 15:09:21 +00:00			`Documentation=man:systemd-battery-check.service(8)`
units: skip systemd-battery-check in environments where it doesn't make sense Let's condition the service so that it doesn't run where we aren't directly run on baremetal, or where no power sources are discovered at all. 2023-07-03 11:36:08 +00:00			`ConditionVirtualization=no`

tree-wide: use "_" rather than "-" as separator in kernel cmdline options Most of our kernel cmdline options use underscores as word separators in kernel cmdline options, but there were some exceptions. Let's fix those, and also use underscores. Since our /proc/cmdline parsers don't distinguish between the two characters anyway this should not break anything, but makes sure our own codebase (and in particular docs and log messages) are internally consistent. 2024-02-28 14:31:27 +00:00			`ConditionKernelCommandLine=!systemd.battery_check=0`
units: add one more equivalency of '-' in '_' on kernel cmdline c0aeff4b999318d4da48328fff0ea93c8c457ace added this in one unit file, but the same problem occurs here. (There are no other files where this would apply.) I think we should solve this systematically somehow, but it's not clear how to do that, so until we have that better solution, let's apply the manual solution so that our units work as expected. 2024-03-19 08:11:45 +00:00			`ConditionKernelCommandLine=!systemd.battery-check=0`

Drop split-usr and unmerged-usr support As previously announced, execute order 66: https://lists.freedesktop.org/archives/systemd-devel/2022-September/048352.html The meson options split-usr, rootlibdir and rootprefix become no-ops that print a warning if they are set to anything other than the default values. We can remove them in a future release. 2023-06-12 01:15:19 +00:00			`ExecStart={{LIBEXECDIR}}/systemd-battery-check`
