From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

How to setup gentoo and snapper together? (lemmy.dbzer0.com)

Hello folks!

So I have installed gentoo a few times before so I am not completely new to it. But I am new to managing things like btrfs and or LVM manually.

So my plan is to install Gentoo with btrfs and snapper so that you can boot in to read only snapshots from grub and rollback once booted. This is what Opensuse Tumbleweed does.

I would like to know which btrfs layout and or LVM layout is required for such a setup. I have been able to find some info that I think requires the /boot subvolume to be on the root of the system. Also some say you need to make the .snapshot volume some say you dont and snapper does this. So their is a fair bit of conflicted info about it to get working right.

Can you explain what your end goal and use-case is? I'm confused on why you want both as they are both capable of each doing each other's jobs in different ways.

What do you mean with both?

Well BTRFS can go back to PiT snapshots and run from there, and snapper is an abstraction for BTRFS...so what's your goal?

Like I said in the post. To set it up just like Opensuse Tumbleweed. I find snapper quite easy to work with and use to rollback from those bootable snapshots. Also it making snapshots after updates is quite useful too
