Do not overload mount-call - trying to reduce confusion
The behaviour of calling 'mount' differed depending on whether it called the busybox-mount, the mount of util-linux, the mount defined in /lib/functions.sh and /lib/functions/boot.sh /etc/preinit even included /lib/functions.sh and /lib/functions/boot.sh, both re-defining 'mount'.
