Does anybody in this sub using Fedora Secureblue?
I do. And have done so for almost a year now.
What is your opinion?
It’s pretty neat. Though, don’t expect to roll your way in without any troubles if you don’t take the effort to read its documentation. Fedora Atomic already does things its own way. However, secureblue, by virtue of its superior security standard, adds its own set of ‘rules’ that one should abide. Personally, I absolutely love how this is enforced. But I can understand why it might be a bit overwhelming for those new on the block. But I have personally helped introduce relative newbs to secureblue and they managed (with some help). So you should be fine; their community on Discord also has been pretty helpful in my experience.
So, if your first priority for your desktop operating system is for it to be Linux-based and your second priority is that it’s properly hardened, then you simply can’t go wrong with secureblue.
I was about to write a long piece comparing different security-focused systems, but I retracted for the sake of brevity. Please feel free to ask a specific comparison if you will.
FWIW, this hasn’t been my own experience. If anything, it may give of some “know-better”-vibes like one might recognize from engaging with some of GrapheneOS’ community members.
