From bca5c556c43ced7b368fdd90a24e4aecf40045ac Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Tue, 12 Mar 2013 10:48:09 -0400 Subject: [PATCH] udhcpc: use readlink rather than realpath The realpath utility requires all paths exist when canonicalizing symlinks. If /etc/resolv.conf points to a tmpfs, then it might not exist initially. Use `readlink -f` so that we follow all symlinks that are available.
