I tried following,

 * add '$rc_local rc.local' into /etc/insserv.conf
 * add 'Required-Start: $rc_local' into /etc/init.d/bootlogd

but it still causes errors from insserv(8). Did I correctly understood
your suggestion?

Still, I think the most straightforward (from interface point of view)
way is to add support inter-depencies between 'Required-Start: $all'
scripts.

Handwavingly, I see following algorithm:

 * split init scripts into two groups -- ones that depends on $all and
   ones that don't
 * Implement topological sorting in both group, ignoring $all in first
   group
 * concatenate resulting ordering

Are there implementation problems, that make is unfeasible?
