Any chance the /usr/share, or even /usr, are on separate filesystems?

On systems with a separate /usr, UFS or ZFS, I usually create the 
/usr/share/misc hierarchy on the root fs, and and place additional 
copies of the termcap* files there. This makes both the Bourne shell 
and the Bourne-again shell happy. As an aid to update these extra 
copies, I mount the root fs as NFS on localhost while in multi-user 
mode.

Hmm, I have never seen problem #2. Is this on base/head? What rev?
