The behaviour of fdescfs and devfs hasn't changed between 8.x and earlier versions. When mounted via devfs, /dev/fd/* will only supply character special devices for descriptors 0, 1 and 2. With fdescfs mounted, you get character special devices for all file descriptors opened by the process. See: http://lists.freebsd.org/pipermail/freebsd-fs/2006-August/002214.html and the definition of fildesc_drvinit() at the end of sys/kern/kern_descrip.c (which cvs blame says is unchanged since 2004). This is not properly documented anywhere I can see. Anyhow, if STD{IN,OUT,ERR} is sufficient for obspamd then the test in the init script could be reduced to if [ -c /dev/fd/0 ] ; then Otherwise, testing for fdescfs is correct.
