03.#Each line describes a limit for a user in the form:
04.#
05.#<domain>        <type> <item> <value>
06.#
07.#Where:
08.#<domain> can be:
09.#        - an user name
10.#        - a group name, with @group syntax
11.#        - the wildcard *, for default entry
12.#        - the wildcard %, can be also used with %group syntax,
13.#                 for maxlogin limit
14.#        - NOTE: group and wildcard limits are not applied to root.
15.#          To apply a limit to the root user, <domain> must be
16.#          the literal username root.
17.#
18.#<type> can have the two values:
19.#        - "soft" for enforcing the soft limits
20.#        - "hard" for enforcing hard limits
21.#
22.#<item> can be one of the following:
23.#        - core - limits the core file size (KB)
24.#        - data - max data size (KB)
25.#        - fsize - maximum filesize (KB)
26.#        - memlock - max locked-in-memory address space (KB)
27.#        - nofile - max number of open files
28.#        - rss - max resident set size (KB)
29.#        - stack - max stack size (KB)
30.#        - cpu - max CPU time (MIN)
31.#        - nproc - max number of processes
32.#        - as - address space limit (KB)
33.#        - maxlogins - max number of logins for this user
34.#        - maxsyslogins - max number of logins on the system
35.#        - priority - the priority to run user process with
36.#        - locks - max number of file locks the user can hold
37.#        - sigpending - max number of pending signals
38.#        - msgqueue - max memory used by POSIX message queues (bytes)
39.#        - nice - max nice priority allowed to raise to values: [-20, 19]
40.#        - rtprio - max realtime priority
41.#        - chroot - change root to directory (Debian-specific)
