Details:
Using hurd 1:0.8.git20160522-4 from Debian:
$ ls -ld hop
ls: cannot access 'hop': No such file or directory
$ touch hop
$ settrans hop /hurd/fifo --multiple-readers
$ showtrans hop
/hurd/fifo
The output from showtrans should have been "/hurd/fifo --multiple-readers".
This happens on ext2fs and tmpfs.
ext2fs uses libdiskfs/file-set-trans.c, which recognizes "/hurd/fifo" and
converts it to S_IFIFO, but ignores the arguments. In contrast, if it
converts "/hurd/symlink" to S_IFLNK, it saves the first argument of the
translator as the target of the symlink (and ignores any remaining arguments).
I think it should check that it understood everything that was in the
arguments, and if not, save the arguments unchanged as if it hadn't recognized
the translator.
