Comments: set_rlimits is a small wrapper program to allow people to take advantage of
the realtime resource limit extensions available in Linux kernels 2.6.12 and
later without having to resort to using a PAM module.  This is of particular
interest for Slackware users since Slackware doesn't use PAM, but other
users may find this program helpful as well.  In addition, several other
resource limits can be manipulated by the program.

set_rlimits needs to be installed setuid root.  However, it runs at
elevated priviledges only when setting the process resource limits.  This
minimises potential security implications.  Despite this, no security
guarantee is given; users concerned about the security of this program
should review the source code themselves.  Suggestions on improving security
are welcomed by the author.

The resource limits which set_rlimits is permitted to grant are controlled
in /usr/local/etc/set_rlimits.conf (change in source: set_rlimits.c).
This file sets the maximum priorities which
set_rlimits can set for a given program when executed by a given user or
group.  The program specified must include an absolute path.  This gives an
administrator fairly fine-grained control over who can execute programs at
elevated priorities and which programs they are.  The enforced specification
of an absolute path in the configuration file means the administrator can
maintain control over exactly which programs may be run with elevated
resource limits.

For further details on the configuration file format, refer to the
/usr/local/etc/set_rlimits.conf.example provided in the extension, or the
source itself.
