toolbox is preinstalled on fedora silverblue/kinoite whereas distrobox isn't. What's the advantage of one vs the other? Why is toolbox preinstalled and not distrobox?
edit: thank you guys! I guess for me this means that I'll use distrobox because it's much more mature or documentation is a little bit better and I do not need (or have) fedora's support
I really wanted to avoid a debate (doubly so in a thread where some dude just wanted some help), which is why I'm trying not to engage the various answers I got; though just one thing since I apparently can't help myself: Qubes, which you cite, is indeed an example of such improved security done correctly, through an hypervisor and a solid implementation; not cgroups, some duct-tape and the same kernel, and thinking your security has improved. Thanks again, at any rate.
Understandable! Please consider coming back to this at some point (also possible in private) as I'm genuinely curious to hear from you.
There are may layers of security that every companies have different approach based by their users / their target customers.
