Running the postinst script manually, I get this error:

+ update-rc.d -s syslog busybox-udhcpc defaults
usage: update-rc.d [-n] [-f] [-r <root>] <basename> remove
        update-rc.d [-n] [-r <root>] [-s] <basename> defaults [NN | sNN kNN]
        update-rc.d [-n] [-r <root>] [-s] <basename> start|stop NN runlvl [runlvl] [...] .
                 -n: not really
                 -f: force
                 -v: verbose
                 -r: alternate root path (default is /)
                 -s: invoke start methods if appropriate to current runlevel

Looks like update-rc.d is not being called properly.  This
was introduced by
   commit 427472e980cd6254a5e4ef37209b327e15af259b
