On my system, /lib/init/rw also contains a hidden directory:

  drwxr-xr-x 2 root root   80 2007-06-04 16:31 .mdadm

Which contains two empty files:

  -rw-r--r-- 1 root root 0 2007-06-04 16:31 md0-uevent
  -rw-r--r-- 1 root root 0 2007-06-04 16:31 md1-uevent

This matches my software RAID setup.

Based on the content of two *.sh files located in /init/lib, I'd think 
this is a system startup directory, used as part of the system's 
initialization (initrd, etc.).

So, maybe it's OK to umount it, presuming that it's no longer used. 
Then again, since I really don't know, perhaps not. ;)
