Heck even moving it to another partition isn’t really a re-install as it’ll happily create the exact 1:1 same system based on nothing but the configuration file, change nothing but the id of the root partition (you’ll have to move over /home manually, though).
And if you mess up your configuration either roll back instantly, or fix it in situ in case you already gc’ed the old stuff. It’s practically impossible to get it into a non-booting state without literally ripping out the disk it’s installed on (or, well, Windows messing up the bootloader or something). Even if you run unstable on the whole system every single commit on that branch is tested to not break boot and rollback.
Oh just one thing: Don’t skimp on the size of your EFI partition. 100M are definitely borderline when you have both NixOS and Windows booting from it, those kernels and initrds have gotten quite large over the years and you’ll need to be able to fit, bare minimum, two of both.
Just moved from Endeavor to NixOS. It’s a huge learning curve and takes a while to build your config or flakes, but damn does it feels nice to just roll back if you mess up over re-installing.
Because I made it unbootable by doing something dumb or one of its tools was horribly broken and made my system unbootable? :) This was years ago, though, it’s probably more stable these days.
While RHEL and Fedora are siblings we can’t mix em’ like that. At least I haven’t ever seen a server with Fedora pre-installed, or anyone offering support on a Fedora server…
We have a piece of fancy and expensive radio equipment in the office, the control part is a Fedora server, with precompiled binaries that run that piece of hardware. Every system library has frozen version, if you upgrade the OS the whole system stops working, and you just reinstall the disk image from the archive, and by reinstall I mean use dd to overwrite the hard drive partition from a supplied DVD.
Huh, at least it’s Linux I guess? I’ve seen plenty Windows XP hanging around controlling expensive medical equipment and one time even a system were the control part was Windows 3.1. Air gapped not for security but because the server didn’t have a NIC.
In the time I have been a Linux gamer, it has gone from “here is a list of games that work in Linux” to “here is a list of games that do not work in Linux.” Which some dictionaries define as “progress.”
In 2003, it was my dream to play FF7 in Linux. In 2019, my dream came true. Thanks Proton, Codeweavers, Wine, Valve, et al for helping me finally put down Sephiroth right.
That’s crazy! When I was last trying to run Linux full time in ~2014, you had WINE and then a commercial version of WINE (not by the WINE devs, but because WINE is licensed the way it is and is open source…) that would run a few more things, but I don’t remember what it was called.
So glad to hear it’s progressing this quickly and far.
