To clarify, what that means is that *systemd* does not impose any limit 
by default. Squid when it cannot find a limit sets 1024 as default.



Under systemd the "correct" way to set such a limit is for the admin to 
decide on a limit and configure it. You can do this is two ways:

  1) set the systemd local config like you did:

or, 2)

   set max_filedescriptors in squid.conf
