(This is http://patches.openembedded.org/patch/36551/ which has been 
archived, but AFAIK I can't reply to the full context because I was 
unsubscribed when the discussion occurred:)

Apologies if my recursive grep skills have failed, but it appears this 
is still not globally resolved for images that use systemd as the init 
manager.

meta-gumstix has this patch and it caused problems with attempts to use 
systemd_v189 in denzil since it's hidden inside a bbappend to 
systemd_git.  So I'm hoping to identify a more forward-looking 
solution.  Is there a plan to fix this issue globally?  Koen preferred 
using base_files+fs_perms as in Angstrom, but Holger was concerned this 
would prevent sharing base_files between sysvinit and systemd builds.
