well not directly, but right klibc-utils should have proper syntax.
initramfs-tools currently uses belows syntax. before we unmounted
and remounted, which is much uglier.

or even better have the util-linux-ng mount compiled against klibc,
haven't looked into that project yet.

a hook script (live-initramfs) seems to add util-linux-ng mount
for cifs support and thus belows error came to sight.
