You can’t however make it use other init system or other DE/WM.

You’re AFAIK correct on the bold part. But definitely not on the strike-through part. You’re probably only limited by your creativity and the effort you’re willing to put into it:

• Bazzite, but with Hyprland
• Bazzite, but with niri
• Bazzite, but Windows-themed | It’s basically KDE Plasma, but you get the point.

Thank you for mentioning it! But I don’t think any of their wallets satisfy the requirements. Please correct me if I’m wrong, though.

RFID protection is often present in wallets, and it would be helpful

Thank you for mentioning this! FWIW, all of the wallets mentioned in the post offer RFID (in some capacity).

I have other places to keep coins

Like where 😜? Looking for inspiration on a robust solution.

Please correct me if I’m wrong, but I’ve come to the following conclusions regarding Bellroy:

1. IIRC, only their Note Sleeve fits the bill (pun intended).
2. IIRC, reports on quality are mixed; i.e. not everyone is fond of it.

Though, I suppose All The Wallets’ review is at least promising regarding the Note Sleeve’s long-term durability. So, I’ll grant it the benefit of doubt and put it on the shortlist. Thank you for mentioning it!

Btw, how have your experiences been with Bellroy wallets?

OP, FYI: GPU passthrough isn’t riskless (OpSec-wise), unfortunately. This Hacker News thread contains pointers if you’d wish to read up on that.
