I've located the source of this issue. Turns out DISTRO_FEATURES_BACKFILL
and DISTRO_FEATURES are concatenated somewhere along the way. The lack of
leading whitespace in the DISTRO_FEATURES_append from the oe-selinux distro
was causing 'sysvinit' and 'pam' to be combined into 'sysvinitpam'. The
check in the packagegroup class that I was running into must be evaluated
before any sanity check for invalid entries DISTRO_FEATURES.

Adding a leading space to the DISTRO_FEATURES_append in the oe-selinux
distro resolves this issue. Thanks for the pointer to the backfill
mechanism Ross. I'll submit a new patch.

Cheers,
