I am trying to install ECE but the prerequisites fail with the following:

`OS settings for max open file descriptors per process should be >= 65536, currently 32768`

That's what I get when I exec in the container and run "ulimit -n" however "cat /proc/sys/fs/file-max" shows 325000.

I have tried "DefaultLimitNOFILE=65536" in /etc/systemd/system.conf and /etc/systemd/user.conf but still failing.

Any suggestions on how to change this?
