Hi,
I've attached a trivial patch for an "initramfs" mount option. The
purpose of this patch is that selected mounts in /etc/fstab can be
identified for mounting in the generated initramfs. This will
permit e.g. mounting of a separate /etc and /usr and any other
admin-configured filesystems prior to init starting.
Uses: encrypted /etc and unencrypted / and /usr
separate /usr mounted with rootfs
- this means libraries and binaries on /usr are available
from the initramfs onward, solving a whole host of
problems with e.g. nss and pam modules having dependent
libs in /usr, etc., which aren't available during boot.
Feel free to change the name to something more generic; this is
intended for use with Debian's initramfs-tools initramfs
generator, but may have potential for cross-distribution use.
Regards,
Roger
