I see reference in login.conf(5) manual page for:
/etc/login.conf.db hashed database built with cap_mkdb(1)
I am using NetBSD 2.1 and have used /etc/login.conf various
times with
older versions of NetBSD.
When is the hashed database .db version used?
Can anything generate it automatically? Or do you always
manually run
cap_mkdb as needed?
What code checks to see if the .db version is available
versus plain text
login.conf?
I don't see the relevant documentation. I am looking at
src/lib/libutil/login_cap.c, getcap(3) man page and other
files.
OpenBSD's login.conf manual page says:
=-=-=-=-=-=-=-=-=-
Sites with very large /etc/login.conf files may wish to
create a database
version of the file, /etc/login.conf.db, for improved
performance. Using
a database version for small files does not result in a
performance
improvement. To build /etc/login.conf.db from
/etc/login.conf the fol-
lowing command may be used:
# cap_mkdb /etc/login.conf
Note that cap_mkdb(1) must be run after each edit of
/etc/login.conf to
keep the database version in sync with the plain file.
=-=-=-=-=-=-=-=-=-
And FreeBSD's, DragonFly's and OpenBSD's getcap(3) manual
page says:
cgetent() will first look for files ending in ``.db'' (see
cap_mkdb(1))
before accessing the ASCII version of the capability
database.
But the FreeBSD Handbook says different:
=-=-=--=-=-=-=-=-
Note: The system does not read the configuration in
/etc/login.conf
directly, but reads the database file /etc/login.conf.db.
To generate
/etc/login.conf.db from /etc/login.conf, execute the
following command:
# cap_mkdb /etc/login.conf
=-=-=--=-=-=-=-=-
How is it done in NetBSD? Where documented?
