Hi,
This series changes the package groups and distro feature setup to allow
simultaneous use of sysvinit and systemd, with a number of fixes that were
discovered on the way.
As before there are sysvinit and systemd DISTRO_FEATURES. These are not
mutually exclusive, and sysvinit is backfilled for compatibility.
Common Scenarios
===
"I want sysvinit, just like before"
Do nothing, sysvinit is backfilled and the image is effectively identical as it
was before this series.
"I just want systemd"
Add systemd to DISTRO_FEATURES, and sysvinit to
DISTRO_FEATURES_BACKFILL_CONSIDERED. You'll only get the sysvinit scripts where
required: when a package doesn't have systemd support.
"I want my main image to boot using systemd, but a rescue image to use sysvinit"
This is less elegant, but can probably be improved later. Add systemd to
DISTRO_FEATURES and sysvinit will be backfilled for you (feel free to add it
explicitly for clarity). Then set VIRTUAL-RUNTIME_init_manager to "systemd" and
any images using package-group-core-boot will boot using systemd. For your
rescue/minimal images I expect you're not using package-group-core-boot anyway,
so pull sysvinit+initscripts into those images however you wish.
Future Plans
===
Mainly, finish integrating the bulk of meta-systemd into oe-core!
There's potential for reducing the footprint of the hwdb by building/patching
udevadm on the host to generate the hwdb.bin file at image construction time,
and then removing the source files leaving just the binary cache. As it is,
udev-hwdb is a recommendation so if your system doesn't actually need it, you
can blacklist it.
Cheers,
Ross
