New Revision: 200413
URL: http://svn.freebsd.org/changeset/base/200413
Log:
Convert pam_lastlog(8) to libulog.
The information used by the "Last login:"-line is obtained by using
ulog_setutxfile(3) to switch to the lastlog database. Login and logout
are performed using the utility functions ulog_login(3) and
ulog_logout(3).
This also means we must build libulog during bootstrap.
