[arch-general] /usr is not mounted. This is not supported.

Don't you have a boot message saying "minilogd not found" or somesuch?

  $ which minilogd -> /usr/sbin/minilogd

By the time /etc/rc.sysinit starts minilogd, /usr is not available, so
there's no minilogd and hence, no log of early boot messages.

I'm thinking of solving this particular problem like this:

minilogd requires the following libs:

-rwxr-xr-x 1 root root 11K Oct 18 18:34 /usr/sbin/minilogd
lrwxrwxrwx 1 root root 12 Sep  9 01:23 /usr/lib32/libc.so.6 -> libc-2.14.so
-rwxr-xr-x 1 root root 1.4M Sep  9 01:23 /usr/lib32/libc-2.14.so
  /usr/lib32/libc.so.6:
  lrwxrwxrwx 1 root root 26 Sep  9 01:23 /lib/ld-linux.so.2 -> ../usr/lib32/ld-linux.so.2
  -rwxr-xr-x 1 root root 141K Sep  9 01:23 /usr/lib32/ld-2.14.so

I don't know why it asks for libs out of usr/lib32, this output is from
(the recursive use of) readelf(1).  This is on a 64bit PC.

So I could "mount -B / /mnt/root" and copy the needed file hierarchy to
/mnt/root/usr/.

On the other hand, rc.sysinit also invokes /sbin/bootlogd, which leaves
most of the interesting stuff in var/log/boot, so this would be an
academic exercise ...
