In my tests, the startup-config directive never worked. Containerlab did copy the contents of srx1.txt to the startup-configcfg but they never got loaded when the lab wsa started. I always had to log into the vsrx and add the commands via the Junos CLI.

Takes approx 5 minutes to boot the vsrx on my old laptop. Intel i5/8G of ram. My laptop does not have enough grunt to run two instances, but one works fine.
