What Are All These Loop Devices? (Ubuntu/Snap Users Often Ask This.)

“DistroTube”
What are loop devices? This is a question that comes up a lot these days, especially from Ubuntu users. This is due to the fact that Snap packages are mounted as loop devices.

they also polute gparted, iam not sure where root is when i see like 12 devices on single partition.
i would happily use snaps on server, just.. get rid of this loop devices plz
Oh man… What's wrong with you, Linux guys? Why don't you just call it "virtual" if it is virtual? Why "loop"? 😵💫
Linux is fun and all but honestly its so frustrating trying to remember specific or "quirky" commands/parameters for one scenario. Like "lsblk -e 7" who comes up with this stuff
This is incredible. So basically I can make a file and mount it as a virtual drive, use it to store data and then copy it on a new system? Copying just one file takes much less time, and I could use this method for my /home directory. This way I can take it anywhere. I could put in on a flash drive and copy to a new system and mout it there
I would've thought that it would be permanent, so it's good that you "diverged" and went over that as well
I hope u have a video on interactive shell setup, auto completion.. i need that
Android uses Loop devices…
Derek, I think you missed the core reason why loop devices are useful.
There is almost no benefit of using loop devices instead of just mounting the filesystem from the image directly if the file is a partition image and contains a valid filesystem. After all, block devices are also files in Unix and it works the same way for ordinary files as well.
But the full disk images are trickier. On Linux, udev automatically creates device files for the individual partitions (sda1, sda2, sdb1, nvme0n1p1, mmcblk0p1, etc.), but there is no equivalent functionality for disk images by default, so you can't mount partitions when they are inside a disk image. One way to get around this is to create a loop device with the offset of that specific partition you want to mount using with -o option and then mounting the loop device — just like as you mount a partition.
Flatpak is also sandboxed and doesn't uses loop devices. How? Why?
Loop de loop
Check out Shufflecake, it takes this Loopback concept and runs all the way away with it for hidden and recursive filesystems.
Why do snaps need the loop devices anyway? Can't they just mount the file directly? SInce everything is a file on Linux, what's the point of guiding the file through /dev/loop?
You can install so many programms that never need loop devices and then theres snap that uses them for stuff like a calculator. I think less people would complain about that if it was actually needed and not just spam when you run lsblk.
Hey DT, can you tell me your system dark gtk theme name which you use in your browsers, pcmanfm etc.. please 🥺.
Pseudo devices or Sudo devices ammirite
Are there any alternatives to Mastadon? New users ruined it. Its like reddit now.
I immediately stopped watching and went on to try the commands, all in /tmp because I'm scared. I'm so glad you accidentally went over them! I put stuff in my image file and mounted and unmount it over and over
can you do similar videos on stuff like sockets, ports, processes, etc.
Should do an video on how Linux boots from power button to graphical application
So, just like .dmg files on macOS? Then it's fine to me, I guess.
i don't have any snaps because flatpaks do what i want them to also not a fan of snaps but if you want to use them that is fine
Just use Debian, guys. There’s such a thing as nonfree repos, backports, testing, and even appimages. There’s no reason to deal with middlemen.
Have a Happy Christmas and a Merry New Year!

This is kinda half ass demo with all the “ I didn’t mean to …”😂 however I do appreciate many of your other videos
That's more soy than I can handle.
This video left me more confused about this topic than I was before.
I see that there are no snaps defined in fstab. Does that mean that snap system has separate tools to auto mount your snaps?
