> To solve this I made a change similar to the one I made to st.c a few days

I just noticed this (hey- I'm supposed to be caring about st- how about
running this stuff by me, or the list). The change you made is wrong I
believe- the check should be against ST_MOUNTED, not PERIPH_OPEN- you now have
allowed somebody to eject a tape manually in the middle of a no-rewind set of
backups and replace it such that the backup apps don't know something has
happened.
