I think that an immutable version of Linux Mint could do substantial harm to Linux adoption.

Hopefully if such a version is created, it will avoid calling itself "Linux Mint".

Otherwise, the community will need to provide additional "but not that version" to new Linux adopters, which is exactly the kind of confusion that can cause a nervous person not to try something new.

I like the idea, in general, but I think we should keep it under completely separate branding to keep it far away from being confused with the "Linux Mint" that we recommend to new Linux users.

Being surprised by a distro that I didn't unerstand was immutable has been a terrible experience, for me. I wouldn't wish on anyone for their first experience on Linux. And I constantly tell people to "try Linux Mint", so I would feel responsible. LoL.
