I should whitelist /opt/minecraft-launcher since swiftshader cache is there and add a note because the executable on some Distros can reside on /opt/minecraft-launcher?

Why? You has already private-opt minecraft-launcher.

Adding a private-opt copies the entire subdirectory?

Ahh you mean removing private-opt and using whitelist instead.

anything left?

anything left?

Deciding on private-etc ,I guess. Are multiplayer known to cause problems with it: minetest,steam etc.?

How do you created it? (Template, --build, --trace, strace, try & guess, strings, …)

I allowed the whole package of files from the template, still didn't work. I made it using the default private-etc that goes with an application with sound,video,3D,internet and depending on terminal spam+strace I add the rest like passwd. Maybe I'll try with strace.

First try --build, much easier. The templates don't cover special things. In general: always check if there is a /etc/.

Build gave private-etc resolv.conf,login.defs,openal,java-13-openjdk,drirc,timezone,fonts,xdg,gtk-3.0,machine-id,ssl,ati,hosts,selinux,passwd I have to check them now. Seems like it was login.defs or timezone.

@rusty-snake Thanks for the tip, I'll add them and ati,drirc,openal?

I tend to java-13-openjdk, if so add it for more java versions.

Nevermind, it was java, I removed the wrong group. How do I add more java versions? Like java-8-...,java-11-... etc. ? I use only OpenJDK, whereas people can use the one from Oracle package or the one that comes with the launcher, I don't know where the last is stored.

Look at i2prouter, signal-cli, terasology. There is no realy good way now.

I'll add all the known ones of OpneJDK from 7-14. So a comment saying to comment this line in case breaks or add your own java folder?

The profile needs sorting (private-bin, private-etc).

Used the python script on it.

+1 from me.

Merged, Thanks.
