  • You can convert a running ext4 system into BTRFS and even move back to ext4, but to optimise the file system there are quite a few tricks to run as well. They come down to “remove the ext4 metadata (can’t go back after that), defragment, balance, maybe defragment again” and there are tools out there that make this stuff doable though the GUI, but I wouldn’t necessarily recommend that approach I novices.

    The cleanest switch would be to reinstall. Not just because of the steps above, but also to make sure the right subvolumes are set up with the right properties. This too can be done from a (mostly) running system, but it’s an absolute pain in the ass to have to do manually, especially if you’re not an expert in command line stuff.

    ext4 works fine if you don’t want to deal with all of this, but you’ll have to keep an eye on things like backup sizes just a bit more often


  • If you can’t take advantage of Timeshift’s BTRFS support, you’ll probably need to keep an eye on disk space regardless.

    All the .deb files are installed across system directories like /usr and /etc. If you only want backups of your files, just exclude everything outside /home and your data drive. This makes it more difficult to recover from a failed upgrade Windows System Restore style (as you exclude the system components from the backups) but hopefully you’ll never need that (or will be willing to reinstall and restore from backup when failure does happen). You may also want to exclude folders like $HOME/.cache and $HOME/.var if they’re present on your system. I think Chrome puts some of its cache in $HOME/.config as well, though I’d back up most .config folders myself.

    If your storage is that limited and you’re already familiar with Timeshift, you may want to consider switching to BTRFS. It’s not very friendly when it’s almost full, but compression and deduplication can save a lot of disk space, especially with tools like Timeshift. Other filesystems also offer these features, but Timeshift doesn’t make use of anything but BTRFS as far as I know.


  • You can probably just swap the SSD if your dock uses a protocol that Windows’ bootloader can understand. Some USB 3.2/Thunderbolt docks just seem to work with Windows, albeit a bit slower because of hubs and such that aren’t always top quality.

    Just try it. It either boots or it doesn’t. If it doesn’t, it’s probably a massive pain to get working in the dock (best of luck to you if you’ll still try).

    You should also check for updates/update your new SSD’s firmware, probably under Windows. Not a lot of brands make Linux installers and the automatic tools that check compatibility generally aren’t part of the Linux firmware downloads.

    Re: file transfer: make sure you have your Bitlocker recovery key, or disable encryption on the Windows partition so you can access it in Linux. Other than that, just copy over the files. Linux can read Windows’ file system just fine. If you load the right drivers, Windows can also read file systems like btrfs or ext4 just fine.


  • A lot of people are afraid of systemd expanding because systemd handles a lot of stuff, so distros are likely to support it rather than the mishmash of tools they personally prefer. It all started with the System-V/Upstart replacement and now very few distros have the patience to customise and roll out the 90s style service management anymore. Their preferences used to align with the mainstream, but no longer do these days, and that causes friction.

    This process pushes people who prefer old tools to fringe distros, and newer software is less likely to work on their setups. They’re still free to use whatever system they like, of course, but the burden for developing and maintaining daemon management scripts is now on their fringe distro or themselves if their distro doesn’t have anything yet. I’d find that pretty annoying too, especially with how convoluted many older system management scripts are and how many moving parts are typically involved. Plus, some stuff like socket activation can’t even be done with some of the older init systems so people have to find alternatives.

    I doubt anyone reeling against run0 was ever going to consider it anyway.


  • sudo had several severe security bugs caused by copying env variables so I’m not surprised run0 isn’t doing much of that. I’ve had to help a whole bunch of people fix the permissions/ownership on their Jo. E directory after running sudo so I can even see the point of jot copying $HOME by default.

    I don’t think it’ll replace sudo necessarily, or doas would’ve done that already. It’s still useful as a shorthand for systemd-run and in some locked down system configurations I can see it being useful (i.e. when minimising the amount of SUID binaries). Maybe some elaborate enterprise setups will switch to it for security reasons, especially if they’re already leveraging PolKit heavily.




  • Unless you have some kind of knockoff SSD, that ūsung SSD looks like something is corrupted to me. usb 1-10 device descriptor read/64, error -71 might be unrelated.

    This could be a problem with RAM defects or overclocking. If your computer is overclocked, try setting it to stock configuration. Also run a memtest to check if your RAM sticks aren’t going bad. I don’t know what might’ve changed between 6.8.9 and 6.8.10 to cause this, but it could just be a coincidence (i.e. the kernel defaulting to a different RAM page that suffers from corruption for whatever reason).

    These messages are actually part of the systemd startup sequence, so the kernel has already loaded at this point. This means the problem may not be the kernel, but the initramfs installed/generated for your computer. You can try regenerating your initramfs on Fedora by running dracut --regenerate-all as root. Before you do that, you may also want to double check your /etc/fstab to make sure nothing accidentally added a swap device for some reason.







  • Administrator is not root. NT AUTHORIRY\System probably comes closest. You rarely need to interact with that account because Window’s security system doesn’t have the same mix of authentication systems most Linux systems have (users + container APIs + PolKit).

    Windows also supports mixed case filesystems just fine. It’s not the default, so your programs will probably screw up, but it’s just a flag. You can also mount filesystems like ext4 and btrfs on Windows (though booting from them doesn’t really work).

    Also, Windows runs Libreoffice and GIMP just fine. You don’t need to, because you have better sofware available (pirated or paid).

    As for security, Windows is MUCH better unless you’re a cybersecurity specialist with too much time in their hands. Most major distros don’t even come with a firewall enabled by default, let alone a firewall for outgoing traffic. And the best AV I’ve seen for Linux is Microsoft’s enterprise version of Windows defender. In terms of hacking tools, they’re mostly written in languages Python, most of them work on either platform.

    For development, Linux has a slight edge, but with WSL2 it really doesn’t matter much.


  • Running Linux on computers with Nvidia hardware proves that Linux and Windows both have their problems dealing with device drivers. Linux’ benefit is that is has higher standards because the kernel devs need to sign off on driver, but that has downsides of turning away potential driver developers (as getting your code into Linux is a quite a complex thing just on its own). Linux also doesn’t have many drivers in general it seems, unless your device has some kind of generic fallback that disables any special features.

    My kernel panics generally don’t display anything, the display just freezes and I need to force reboot the computer.



  • Votes federate, but only for communities followed. I won’t see your votes in a community that I don’t follow, but I can see when you upvoted or downvoted what post in the community.

    A scraper could simply follow every community on a Lemmy server and, barring Lemmy performance issues, will receive all comments and votes.

    Just a quick and dirty SQL query of which votes of yours are in my server’s database:

    select comment_like.score as score,comment_like.published as when, person.actor_id as who, comment.ap_id as what from comment_like join person on person.id = comment_like.person_id join comment on comment.id = comment_like.comment_id where person.actor_id = 'https://lemmy.ml/u/GolfNovemberUniform' order by comment_like.published desc; 
    

    The same info is also available for posts, of course, I just didn’t want to bother making the query any longer.

    Server admins/mods on Lemmy also have a button to see who upvoted and downvoted each post. This is just the inverse of that.
