From the bash manual: 3.6.1 Redirecting Input Redirection of input causes the file whose name results from the expansion of word to be opened for reading on file descriptor n, or the standard input (file descriptor 0) if n is not specified. The general format for redirecting input is: [n]<word http://www.gnu.org/software/bash/manual/bashref.html#SEC38 So, as bash starts myprog, it opens /path/to/pfinet and inserts the resulting file descriptor into the program as fd 3. > (1) Assume a chroot process invokes "settrans -cp /foo /hurd/firmlink /". > > (2) The fs server will associate node /*foo* (/chroot/foo) with translator * > firmlink*.

The translator does not necessarily know a symbolic representation for the capability passed to file_reparent.
