Somewhere before where Squid is started, ensuring that the new ulimit is
active when Squid is started.

In addition you need this setting before you compile Squid.

/root/.bashrc is not such place. This only changes the ulimit on
interactive login as root.

I usually place this in the boot script that starts Squid, just before
Squid is started.

In addition I change the hard limit for all interactive users in
/etc/security/limits.conf but leaving the soft limit at its default,
allowing all users raise their limit at any time.

It is not wise to change the system wide soft limit. Most if not all
applications assumes the limit <= 1024.

This is ok.

This is not.
