Hi Alex, the runit program didn't change from 1.4.1 to 1.5.0 or 1.5.1,
so downgrading should not help.  I'm not yet completely sure what the
actual problem is, but have an idea.  Can you please test the patch
below?:

 cd /package/admin/runit
 patch -p0 </the/attached/diff
 package/install
 ln /sbin/runit /sbin/runit.old
 install -m0755 command/runit /sbin/runit
 reboot

Thanks, Gerrit.
