NAME
     fbtab -- change device protection upon login

DESCRIPTION
     The fbtab file contains lines which specify how the permissions and own-
     ership of various system files should be changed based on the user's lo-
     gin device	name.

     Comments start with a `#' and extend to the end of	the line.  Blank lines
     or	lines with only	a comment are ignored.

     All other lines consist of	three fields delimited by whitespace.

     Login Device	   The device you have logged in on (e.g.,
			   "/dev/ttyv0").

     File Permission	   An octal permission number (0600), as used by
			   chmod(2).

     Other devices	   The final field is a	colon (`:') delimited list of
			   devices (e.g., "/dev/console:/dev/fd0a").  All de-
			   vice	names are absolute paths.  A path that ends in
			   "/*"	refers to all directory	entries	except "." and
			   "..".

     The fbtab file is used by login(1)	to chown(2) the	specified files	to the
     user who has performed a login.  Additionally, chmod(2) is	used to	set
     the devices to the	specified permission.  When a user logs	out, init(8)
     is	responsible for	performing the inverse operation, which	results	in the
     files once	again belonging	to root.
