Unfortunately, the initscripts changes have not been uploaded and the change to util-linux is unlikely to be accepted. initramfs-tools version 0.118 therefore does not mount /usr unless it detects that the init program is systemd. > The initramfs can fsck and mount /, /usr and /etc. / and /etc > are configured using the kernel command-line.

We also found that fsck complained if the RTC is set to local time, because the system time is not correct initially. This has been fixed in initramfs-tools 0.118 by copying hwclock and related files into the initramfs. It required a minor change to util-linux to avoid adjusting the system time twice. We also found that the commands in klibc-utils were missing some of the necessary options to support this. An initramfs built without busybox would not boot. These options have been implemented and initramfs-tools version 0.118 has a versioned dependency to ensure they're supported.
