Bug 365243 – sys-apps/openrc feature request: Per-service ulimit

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Patrick Lauer 2011-04-28 20:14:28 UTC]

Similar to bug #361073 - 

I'd like a simple way to define service limits, for example postgres should not have any limits, but lighttpd shouldn't use more than 100MB.

A variable in /etc/conf.d/$servicename would be most convenient, that way I could set ULIMIT="-m 100000" and have that service limited to 100M per process.

System-wide limits are not that useful in this case, but as far as I remember the ulimit values are inherited to children, so anything started from the init script should inherit the given per-service limits.

doesnt pam already do this for you ?

[Comment 2 Robin Johnson 2011-05-01 05:26:27 UTC]

This is already available.

rc_ulimit="-m 100000"

See the main rc.conf.

As far as I can tell that's a global limit - if not then the documentation on it should be extended and a per-service example given.

The following is the section heading in rc.conf for the section where
rc_ulimit is documented:

##############################################################################
# SERVICE CONFIGURATION VARIABLES
# These variables are documented here, but should be configured in
# /etc/conf.d/foo for service foo and NOT enabled here unless you
# really want them to work on a global basis.

I do not see that there is anything for us to do for this bug.
