Subject: [PATCH 1/2] fix _getcmdline arg-duplicating bug with /etc/cmdline*
Newsgroups: gmane.linux.kernel.initramfs
Date: Tuesday 1st May 2012 18:08:33 UTC (over 5 years ago)
If you unset CMDLINE to make _getcmdline re-read /etc/cmdline and
/etc/cmdline.d/*, CMDLINE_ETC and CMDLINE_ETC_D would keep their
contents.

This is a serious problem if you have (e.g.) "ip=eth0:dhcp" in
/etc/cmdline.d/net.conf, because getargs ip= will return
"ip=eth0:dhcp ip=eth0:dhcp" and then parse-ip-opts.sh will die() because
you have two configurations for eth0.
