Bug Description

when both, root= and systempart= are set on the cmdline (specifically if root= points to /dev/ram) the root= parameter will always be preferred. for an immediate solution there was a fix uploaded in initramfs-tools to make root=/dev/ram ignored when systempart= is set in 0.103ubuntu15.

while this helps in the specific case of phones that hardcode root=/dev/ram on their kernel commandline, we need to consider if it makes sense to always ignore root= if systempart is set or if there is any sane combination of systempart= and root= that would require us to keep root=.

summary: - fixrtc allows setting of root= at the same time as systempart=
+ fixrtc allows setting of root=/dev/ram at the same time as systempart=
