From 9fed24c031a885264a9249eed3b6c654c32ce139 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Wed, 27 Feb 2013 01:05:34 -0500 Subject: udhcpc: tweak math shell style with the metric var Some shells (like dash) are lame and omit the POSIX increment/decrement feature (because it is listed as optional). Tweak the shell script to work in all POSIX variants.
