If you want to *restrict* users' resource usage (as opposed to just
helping them to guard against runaway processes), then:
a) You need to set hard limits (with `ulimit -H ...'). A user can
increase a soft limit.
b) You need to ensure that the ulimit command is executed. If a user
sets their shell to e.g. tcsh, or they arrange for commands to be run
via cron, ~/.forward etc, the contents of /etc/profile won't have any
effect.
Having said that, once a limit is set, it is inherited by all child
processes (hence the use of /etc/initscript).
