2019-04-13examples/udhcp/simple.script: fix resolv.conf update if it is a dangling symlinkRolf Eike Beer
If /etc/resolv.conf is a symlink to a tmpfs and the actual file does not already exist, "readlink -f" will not detect it as symlink. Explicitely check for that condition before and touch the file, making the other code work as intended.

2018-10-30examples/udhcp/simple.script: add possibility to use modern "ip"Jiří Prchal
Script uses "ifconfig" only, not up-to-date so much. This patch adds "ip" in condition if exists. Signed-off-by: Jiří Prchal <jiri.prchal@aksignal.cz> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2013-03-12udhcpc: use readlink rather than realpathMike Frysinger
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. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2013-02-27udhcpc: tweak math shell style with the metric varMike Frysinger
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. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2013-02-27udhcpc: support resolv.conf symlinksMike Frysinger
Often it is desirable to have /etc/ be on read-only storage (well, the whole rootfs) but have things like /etc/resolv.conf be symlinks to a writable location. Tweak the simple script to support that. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Erik, Attached is a patch for the udhcpc sample scripts, to correct the order in which routers are applied if the DHCP server provides more than one (as per section 3.5 of RFC2132). Apologies for not being on the mailing list and thanks for your continued efforts. Simon.
