%description
The file /etc/initscript is used by init to execute the commands in
/etc/inittab. As any process it started from init, it is a convenient
place to adjust per process limits (rlimits).

The script provided here does set limits on the memory usage per
process (amongst setting other limits) and thus prevents that a single
process that leaks memory can cause your system to run out of memory
and provoke the system to crawl (trash on the swap partition) before it
rescues itself by killing processes (but unfortunately does not always
hit the right process with the first try). The script sets the limits
in percent of available memory, thus the defaults may match a large
range of systems.

Configuration is done in file /etc/sysconfig/ulimit.

Per user rlimit settings can be configured by filling in
/etc/security/limits.conf and using the pam_limits.so functionality.

More finegrained resource management (per process group), can be done
via control groups (containers) with SLE11/openSUSE11.1 or newer.

%changelog
* Mon Oct 27 2008 garloff@suse.de
- ulimit-1.2:
  * Allow unlimited limits (bnc 382908, bnc 375673)
  * Allow absolute memory limits
  * Refactor (shorten file significantly and clean up environment)
  * Document changes in sysconfig.ulimit file
  * Much more conservative locked memory defaults (still more than
  the kernel default).
* Tue Aug 14 2007 garloff@suse.de
- sysconfig Path missed a colon (299847)
* Sat Jan 20 2007 garloff@suse.de
- Make robust against existing and empty /proc/meminfo (227742)
  (and avoid forks for sed at the same time)
* Wed Jan 25 2006 mls@suse.de
- converted neededforbuild to BuildRequires
* Mon Nov 28 2005 garloff@suse.de
- Fix comment for the stack limit (#132902).
* Fri Apr 01 2005 garloff@suse.de
- Make script work with both pre- and post 2.6.8 kernels. (#74085)
* Sat Mar 26 2005 garloff@suse.de
- Adapt order of applying soft vs hard limits to peculiar 2.6
  requirements for all limits. (#74085, #49323, #60650)
* Sat Mar 26 2005 garloff@suse.de
- Use eval exec "$4" to invoke binary (#74221, #60650).
* Fri Sep 24 2004 garloff@suse.de
- Don't set a limit for locked mem by default. Triggers warning
  with latest 2.6.9-rc kernels. (#SUSE45650)
- Document that the stack limit should not be set either, as
  NPTL uses this a stack size for multithreade programs.
* Sun Mar 28 2004 garloff@suse.de
- Kernel 2.6 needs the soft limits before the hard ones. (#SUSE34323)
* Fri Feb 06 2004 hmacht@suse.de
- building as non root (#norootforbuild)
* Fri Aug 15 2003 garloff@suse.de
- Remove left-over debug output to /tmp
- Specify Command: killall mingetty to restart some service using
  the new limits. (We miss sshd and xdm.)
* Tue Aug 12 2003 garloff@suse.de
- Update to 1.1: Collect arguments first to reduce the number of
  calls to ulimit. (Performance improvement.)
* Sat Aug 09 2003 garloff@suse.de
- Creation of SuSE package.
