Linux: is wine a potential threat for our BTCs?

[LoyceV]

Do you think wine represents a potential risk for his funds?

Safe assumption: of course! Any software adds a risk. Depending on the risk level, I'd run it in a VM, on a different system, or as a different user. After all, you're using a multi-user system, and there's no need to risk it. Use permissions to keep things apart.

Example:
To run wine as a different user, create a new user "wine". Give user "wine" access to your display:

Code:

xhost +SI:localuser:wine; su - wine

Then, as user "wine":

Code:

export DISPLAY=:0.0

Note that I haven't used this for wine, but I did for other programs. If I have to use wine, I run it inside a VM with VPN, because I don't trust the programs I use with it. Or on a spare laptop which is setup to wipe and overwrite in minutes.

Thank you for all your answers!
It's extremely interesting to read.

I quite agree with NotATether, for a lambda user, some solutions seem too complex to implement (but extremely interesting anyway!).
So, for my friend (who is an advanced user but neither a dev nor a specialist) I imagine that the solution mentioned of using a different user for wine would be the best one:

I'll try to motivate him and help him get it right, and I'll come back to this topic if I have into any problems...

In any case, guys, your answers confirm my initial idea: without knowing exactly what you're doing, it's better to play it safe with software (you'll tell me "as always"  )

Wine can be very buggy and not all win software will even run properly on linux os.
Few years ago I was experiment with using some adobe software with wine, but I was not happy with results.
I think it would be much better to separate things and keep everything bitcoin related on separate laptop, even better if you can keep it airgapped.

I don't use Linux regularly I only use it for tests when it's required. If I did use it instead of Windows I'd say it isn't worth the risk of losing bitcoin to a software so wouldn't use wine on the same computer. If ppl want to run a full node or keep their wallets on a computer it's better if they use software that's essential.
