Blank lines are ignored. -.Pp -The first field is a pathname prefix to match -against the requested pathname. -If a match is found, the second field -tells the daemon what type of object to create. -Subsequent fields are passed to the creation function. -.Bd -literal -# @(#)portal.conf 5.1 (Berkeley) 7/13/92 -tcplisten/ tcplisten tcplisten/ -tcp/ tcp tcp/ -fs/ file fs/ -.Ed -.Sh FILES -.Bl -tag -width /p/* -compact -.It Pa /p/* -.El -.Sh SEE ALSO -.Xr mount 2 , -.Xr unmount 2 , -.Xr fstab 5 , -.Xr mount 8 -.Sh CAVEATS -This filesystem may not be NFS-exported. -.Sh HISTORY -The -.Nm -utility first appeared in -.Bx 4.4 . diff --git a/sbin/mount_portal/mount_portal.c b/sbin/mount_portal/mount_portal.c deleted file mode 100644 index 48cf609..0000000 --- a/sbin/mount_portal/mount_portal.c +++ /dev/null @@ -1,295 +0,0 @@ -/* - * Copyright (c) 1992, 1993, 1994 - * The Regents of the University of California.
