Is it possible to control the location of the lock file when starting postgres?

+ /usr/bin/initdb --pgdata=/usr/xxx/databases/pgsql/data --auth=ident

without issue however when I try to start the database it complains about the lockfile.

I know I can change permissions of /var/run of course but I want to change the location of the lock file to a directory I already have access to. So I really want to change the default location of the lock file to something other than /var/run. I've checked the options to initdb as well as looking at the various files in the data directory, pg_hba.conf, pg_ident.conf, etc.

Thank you.
