While most of the target's contents are split into subtargets, the base-files are maintained for the target as a whole. However, OpenWrt already implements a mechanism that will use (and even prefer) files in the subtargets' directories. This can be exploited to make several scripts subtarget-specific and thus save some space (especially helpful for the tiny devices). The only script remaining in parent base-files is /etc/hotplug.d/ieee80211/00-wifi-migration, everything else is moved/split. Note that this will increase overall code lines, but reduce code per subtarget. base-files ipk size reduction: master (generic) 49135 B split (generic) 48533 B (- 0.6 kiB) split (tiny) 43337 B (- 5.7 kiB) split (nand) 44423 B (- 4.6 kiB) Tested on TL-WR1043ND v4 (generic) and TL-WR841N v12 (tiny).
