+  depmod
+    busybox lacks a way to update module deps when running from firmware without the
+    use of the depmod.pl (perl is to bloated for most embedded setups) and or orig
+    modutils. The orig depmod is rather pointless to have to add to a firmware image
+    in when we already have a insmod/rmmod and friends.
