Ping.

This is needed for rocko (assuming systemd with musl is expected to
work with rocko?) so unless there are still strong objections I
recommend merging as-is.

More significant re-work (e.g. preventing systemd-tmpfiles from being
enabled without systemd-sysusers or patching systemd to remove any
dependency on the wheel group) would not be suitable for rocko, so
should be considered separately.

The default systemd-tmpfiles config file expects to be able to create
files etc belonging to the wheel system group. Unless we patch or
over-ride the default systemd-tmpfiles config file to change that then
yes, the wheel group appears to be necessary for systemd.

For sysvinit, we follow the Debian rule which doesn't have wheel group 
in the system. Should we have to break this rule for systemd? Is this 
necessary to use this group in systemd?

Ping.

Ross, it looks like you've started to stage the later systemd + musl
cleanups in mut. This fix is needed too.

In the current recipe, there's no control of tmpfiles (so it will
always be enabled) and sysusers is controlled by PACKAGECONFIG
(enabled by default - but only when building with glibc), so the
recipe does allow that combination.

I didn't know that this is optional. To me it sounds like an invalid
(or let's say, unexpected) configuration to install tmpfiles config
files but not the sysusers files, because as you said, the tmpfiles may
depend on the sysusers.

Anyway, I just wanted to know because I was wondering whether it is
really necessary to duplicate the user creation information in the
systemd recipe.

systemd_create_users() does a build time pass over the
systemd-sysusers config files, but those files are not installed if
systemd is configured without sysusers support.

Isn't this something that the systemd_create_users rootfs postprocess
command in rootfs-postcommands.bbclass already takes care of?

I know that it is has issues (https://bugzilla.yoctoproject.org/show_bu
g.cgi?id=9789), but it should at least create the wheel group.

[OE-core] [PATCH] systemd: create wheel sysuser group offline

[Andre McCurdy]

The default systemd-tmpfiles config file expects to be able to create
files etc belonging to the wheel system group. Currently the wheel
group is created at run time by systemd-sysusers, but that doesn't
happen if systemd-sysusers is disabled (as it currently is by default
when building with musl libc).
