You forgot the huge mapping between different service names. Then
complex mapping from services that are split/merged. Next we need a tool
that will update conf.d for OpenRC services which are split in systemd,

Names aren't consistent between Debian and Red Hat either so that isn't really
an issue.

[gentoo-dev] Checking if a package respects LDFLAGS
Hi, Is there a recommended method for testing if a package respects LDFLAGS? Arch testers are encouraged to add -Wl,--hash-style=gnu to LDFLAGS [1],[2] and portage uses scanelf to check for .hash sections. However it appears that ld defaults to using a .gnu.hash section: $ touch test.c $ gcc -o libtest.so -shared test.c $ scanelf -qyRF '#k%p' -k .hash libtest.so $ scanelf -qyRF '#k%p' -k .gnu.hash libtest.so libtest.so Maybe I'm missing something obvious.

In theory at least, that's easy enough, just check the kernel
commandline's (/proc/cmdline) init= if present, and fall back to matching
against the path (canonical, to take care of symlink-based init-
switching) of PID 1 if init= isn't present or points to the default
/sbin/init.
In practice I suspect one would need to arrange for each supported init
system to drop its own detection executable in place, making the script
something like this:
#!/bin/bash
initdetectpath=/lib/initdetect
if ${initdetectpath}/issystemd ; then
...
elif ${initdetectpath}/isopenrc ; then
...
But, once you're having the initsystems package their own detection
files, you might as well simply make them their own service scripts
designed to do the detection as well, returning a specified error code if
it's not that initsystem, making it as simple as:
#!/bin/bash
notme=
for $servicefile in /lib/initservicedir/* ; do
$servicefile "$@"
code=$?
[[ $code = $notme ]] || break
done
[[ $code = $notme ]] && /
echo "No supported initsystem claimed to be running" > /dev/stderr
exit $code
Then it's up to the initsys packagers whether they want to support the
scheme or not, what sort of detection they do if they support it, and how
they translate the passed parameters if necessary, and bugs in how they
do any of it become the bugs of that initsystem.

How about something similar to Fedora's binary annotations work, or injecting a .note.gentoo section into binaries (containing literal C/CXX/LDFLAGS would be useful). -- Robin Hugh Johnson Gentoo Linux: Dev, Infra Lead, Foundation Asst.

Also, starting/stopping services requires identifying the service manager, not init. You could be running sysvinit without running openrc. Sure, systemd is both an init and a service manager, but it doesn't have to be that way. I'm not sure what runit runs as PID 1. Certainly distinguishing between the old baselayout-1 and openrc would not be possible just by looking at PID 1. Of course, assuming sysvinit=openrc might be a reasonable interim design if somebody doesn't suggest a better approach. I suspect that inspecting /run might be your best bet here. It seems like the world would benefit from some kind of standard for service managers to identify themselves when they're running. In an ideal world they might even expose an API of sorts via a set of scripts in /run (likely symlinked). That would also potentially eliminate the need for a generic service script in the first place. I point these out as issues to be resolved, not a reason to give up. If somebody thinks a generic service script would be useful they should write one. The fact that it isn't trivial actually suggests that a dedicated utility is the right solution vs just having everybody embed their own logic in their own scripts, likely also not thinking of the above issues. -- Rich

With a "[ $# -eq 2 ]" test and with "env -i set_some_envvars
/etc/init.d/${1} ${2}" (and use "rc-service ${1} ${2}" instead of
"/etc/init.d/${1} ${2}")

It's not init that you want to check, it's rc.
For openrc, "[ -d /run/openrc ]" should do the trick.
For systemd, the canonical way is "[ -d /run/systemd/system ]".
