Hi,
While reading on login.conf(5), can't find "tc" capability mentions.
But, examples & usage are demonstrated in /etc/login.conf. After some
search and readings, found out that it has a few paragraph explaining in
getcap(3):
"A special capability, tc= name, is used to indicate that the record specified
by name should be substituted for the tc capability. tc capabilities may
interpolate records which also contain tc capabilities and more than one tc
capability may be used in a record. A tc expansion scope (i.e., where the
argument is searched for) contains the file in which the tc is declared and all
subsequent files in the file array.
When a database is searched for a capability record, the first matching record
in the search is returned. When a record is scanned for a capability, the
first matching capability is returned; the capability :nameT@: will hide any
following definition of a value of type T for name; and the capability :name@:
will prevent any following values of name from being seen.
These features combined with tc capabilities can be used to generate variations
of other databases and records by either adding new capabilities, overriding
definitions with new definitions, or hiding following definitions via `@'
capabilities."
I though it should be mention in login.conf(5). Attached is a diff
inserting "tc" capability into the table of login.conf(5).
Comments?
Regards,
Edward.
