What of Marcus's example:

Here, it looks as if /hurd/ftpfs is being executed with exec (by /bin/sh,
with the special "environment" already existing around it due to settrans),
so if settrans had added /hurd to PATH for the subshell,
$ settrans -ac ~/ftp /bin/sh -c "LD_LIBRARY_PATH=/lib/debug ftpfs ftp.debian.org:/"
would work.
