sysctl -w kernel.shmmax= fails to survive a reboot

[saphil]

sysctl -w kernel.shmmax=120337984
is required to get my highly ptuned postgresql-9.1 server to start on a 10.04 LTS server.
From what I have found, the -w is supposed to stand for "write to system config file" not "well, it might happen if you wish hard enough."

What am I doing -wrong?

-w makes the change temporarily for the current boot. To make it permanent, add it to the end of /etc/sysctl.conf:

kernel.shmmax = 120337984

Thanks! I have read that before but since that file is full of network packet-handling directives and nothing else, it seemed unlikely.

I will try it and see
