When passing the target name as "bootchooser.active", Linux will not
pass the parameter as environment variable to the init process. The only
way to get the bootchooser result (e.g. in an initramfs), is to parse it
out of /proc/cmdline (requires mounting of /proc, sed, ...).
After renaming, the bootchooser result will be passed as environment
variable which can easily accessed from /init (e.g. for selecting the
associated root fs).
