>Description:
The examples in /etc/login.conf use two possible values for "unlimited" (unlimited and infinity).

A look in the source code (usr.bin/limits/limits.c, Revision 1.14, line 497 - 500) reveals that there a FOUR possible values to express unlimited:
- inf
- infinity
- unlimit
- unlimited

Unfortunately there is no explanation in man login.conf at all.
>How-To-Repeat:
