 > commit f79a420825479c47d (package/busybox/udhcpc.script: support RFC3442
 > static routes) used 'set --' clobbering the positional arguments, causing
 > the action argument to not be correctly forwarded to hook scripts for the
 > renew / bound cases if static routes are provided by the server.

 > As a workaround, save the action argument at the beginning of the script and
 > use that when calling hook scripts.
