Automatically launch and exec new lxc container when opening new Terminal tab

If you happen to throw most things into containers, I think this a handy trick for lazy people like us.

* It is somehow an idea inspiring from Firefox TabContainer

Here is the trick, so Gnome Terminal supports different profile and most terminal apps maybe, too. Inside profile you can execute a different program, this is what I did:

sh -c 'NEW_NAME=AG-$(shuf -n1 /usr/share/dict/words|tr -d [:punct:] ) && lxc launch images:ubuntu/18.04 $NEW_NAME && lxc exec $NEW_NAME bash'

Starting from Catalina only 64-bit will be allowed to run, otherwise you see a warning:

And compiling Treesheet from source code is a bit tricky. Luckily I found that in the CI worfkflow the daily builds already in 64-bit.

Here is where you can find it. Goto the actions from official repository, and click on the latest successful build, eg: https://github.com/aardappel/treesheets/actions/runs/119194981
