Does "inherit " work?
I mean empty inherit when DISTRO_FEATURES don't contain sysvinit? IIRC
it will fail to parse.
The above syntax does now work. A plain "inherit " won't but something
with an expression in does get handled correctly. It did not used to
work with older bitbake versions.
The syntax works but that expression won't. If sysvinit was backfilled
(pending patch from Marcin) because the distribution didn't pick
sysvinit or systemd explicitly, the backfill happens after this
expression is parsed.
I'm testing a change where these tests happen against
DISTRO_FEATURES_INITMAN instead now.

It seems that the backfill happens *before* this expression is parsed.
I tested it with DISTRO_FEATURES explicitly set in local.conf (basically
the default value, except that it contains no init manager). It worked
out well.

I also added the following lines to volatiles.bbclass to examine the
DISTRO_FEATURES when parsing the volatiles.bbclass.
+python __anonymous() {
+ bb.error("DISTRO_FEATURES: %s" % d.getVar('DISTRO_FEATURES', True))
+}

inherit
${@base_contains('DISTRO_FEATURES','sysvinit','volatiles_sysvinit','',d)}
And the DISTRO_FEATURES contains 'sysvinit'.
