Autorefresh can lag the server when certain Lua files are edited. This happens when the refreshing cascades. This can be unwanted behaviour when editing the scripts of a large project on a live server.
To disable autorefresh, add
-disableluarefresh to parms.
Loading screens are added by defining a website with
sv_loadingurl, which is in gmodserver.cfg by default. This file overrides other files.
Links should not have
http:// or an ending
Gamemode is changed by editing start parameters in the LinuxGSM config file.
Default gamemodes:TTT gamemode="terrortown"Sandbox gamemode="sandbox"
Other gamemodes like Zombie Survival can be found on the steam workshop.
