Suspicious
I’d recommend trying fedora/nobara(derivative of fedora focused on gaming) it’s widely supported cuz it’s one of the big 3 distris but with much newer packages than Debian but your not getting all the new software the moment it drops like Arch so it’s more stable, they’re very solid distris and automatically support snapshots(they allow you to rollback to previous file states for the entire system without taking up a tonn of memory if you somehow fuck your system). I, at least never had a problem gaming on them and found them to be ideal all-rounders in general
As for running executables you may need to modify permissions with the chroot command, additionally you may need to sudo to run it
I think emulating twitter was a huge mistake for mastadon, the twitter reply structure that makes it difficult to have a long conversation with multiple people to be the main part of the post but ideal for “dunks” and outrage farming. I think the Tumblr reblog structure would have been an infinitly better choice for the more actual socialising thing fediverse is going for and a small user base that isnt producing much content and can re-circulate older posts. also it’s less image-centric allowing more posts to be stored on a server, additionally (intuitively, I haven’t thought about implementation that hard) it seems like a much more natural fit for federation.
