It has taken me a while to get around to asking this question but I am in need of the answer now that I am finally ready to get Cinelerra working on MGA3 & 4.

My MGA2 setup has an entry in my /etc/rc.local file:

Code: Select all

#!/bin/sh
#
### BEGIN INIT INFO
# Provides: rc.local
# X-Mandriva-Compat-Mode
# Default-Start: 2 3 4 5
# Short-Description: Local initialization script
# Description: This script will be executed at the end of the boot process.
#              You can put your own initialization stuff in here if you don't
#              want to do the full Sys V style init stuff.
### END INIT INFO

touch /var/lock/subsys/local
echo "0x7fffffff" > /proc/sys/kernel/shmmax


I have been doing that for years and whilst I confess that I don't remember why I put the shmmax setting there, it has always worked.

Now in MGA3, and 4 too I reckon, there is no rc.local and no place I can think of to get this setting applied on every boot.

As an alternative, if somebody knows how I can change the setting per user logon, that might be even better.

Any ideas?

Please search the forum, rc.local has been asked already pretty often.

thanks Doc, not so much interested in rc.local as in a better way to set it or not set it, depending on how I log on.

Hmmm Searched for rc.local and got 961 matches - and no, I didn't read them all. I searched for shmmax instead and got a solution wich does work for MGA3 but thanks to the moving target which is systemd it is unlikely to work beyond MGA4 if indeed I can get it to work there.

The method I took came from a suggestion from viewtopic.php?f=7&t=7190&p=45987&hilit=shmmax#p45987.

I created a file in the empty directory /etc/sysctl.d. I called it 99-sysctl.conf and it contains

Code: Select all

kernel.shmmax=0x7fffffff

On reboot all is well so I reckon I can safely use this on the Cinelerra machine running MGA3. I'll see how I get on with the MGA4 when I have built Cinelerra there.
