+pam_limits — PAM module to limit resources
+
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+
+DESCRIPTION
+
+The pam_limits PAM module sets limits on the system resources that can be
+obtained in a user-session. Users of uid=0 are affected by this limits, too.
+
+By default limits are taken from the /etc/security/limits.conf config file.
+
+OPTIONS
+
+change_uid
+
+ Change real uid to the user for who the limits are set up. Use this option
+ if you have problems like login not forking a shell for user who has no
+ processes. Be warned that something else may break when you do this.
+
+conf=/path/to/limits.conf
+
+ Indicate an alternative limits.conf style configuration file to override
+ the default.
+
+debug
+
+ Print debug information.
+
+utmp_early
+
+ Some broken applications actually allocate a utmp entry for the user before
+ the user is admitted to the system. If some of the services you are
+ configuring PAM for do this, you can selectively use this module argument
+ to compensate for this behavior and at the same time maintain system-wide
+ consistency with a single limits.conf file.
+
+EXAMPLES
+
+These are some example lines which might be specified in /etc/security/
+limits.conf.

+* hard rss 10000
