The only chance of getting stuck is the following loop:

_dir="/whatever/path/no/matter/how deeply/nested"
while [ ! -d "$_dir" ]; do
  _dir=${_dir%/*}
done

This loop is only ever entered when the path starts with a slash.

I assumed that "/" is always a directory. Might this assumption be wrong
in some strange edge case?

Amitai, can you put a "set -x" above this loop in bootstrap/bootstrap
and try again?
