And these problems are best fixed through the new /rescue tree.  I was
pleasantly surprised to find that the net space consumed by 5.0-CURRENT in
/ for /stand, /sbin, and /bin was substantially larger in the statically
linked world than the space required for / with /rescue, /sbin, and /bin
in the dynamically linked world.  I.e., I can now update boxes installed
with smaller root file systems from earlier 4.x releases without running
out of space, whereas before I would run out of space.
