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.
#
DISTRO ?= "poky"
DISTRO_FEATURES_LIBC_DEFAULT = "ipv4 ipv6 libc-backtrace libc-big-macros

libc-crypt-ufc libc-db-aliases libc-envz libc-fcvt

libc-posix-wchar-io"
DISTRO_FEATURES_LIBC = "${DISTRO_FEATURES_LIBC_DEFAULT}"
DISTRO_FEATURES_LIBC_class-nativesdk = "${DISTRO_FEATURES_LIBC_DEFAULT}"
DISTRO_FEATURES = "alsa argp bluetooth ext2 irda largefile pcmcia
usbgadget usbhost wifi xattr nfs zeroconf pci 3g x11
${DISTRO_FEATURES_LIBC}"
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'.
