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.

BTRFS Question (lemmy.today)

I've been using Mint for a number of years and I encrypted the drive. An annoyance is I have two drives and the second one needs a different encryption and needs to be mounted seperately when I log in (besides if I tell it to automount with a saved password) I've been looking to change distros and finally chose one, this time though it uses BTRFS. I read over a number of differences but am not technical enough to know what it all means.

My question for now is with BTRFS, when installing the distro, can I tell it to use my second drive as an extension of the main drive so it all gets recognized as one, seamless?

Your best options when you are already doing a fresh new install:

make both drives one virtual one with LVM, then encrypt that virtual drive

But that's not related to BTRFS at all and can be done with any file system

encrypt both drives with the same password, format them as BTRFS raid0 (again making it one big virtual drive), use the systemd hooks in your initramfs because then the first password you will provide on boot will unlock both drives (only if this fails on the first try you will be asked for additional passwords - also if you mistype your password once you will then have to unlock both by typing the password both; you only get one attempt to unlock everything with the same password).

If you can do this is mostly depending on the specific installer (I would assume only the first option works by default...). It's definitely possible in general but "I'm not technical enough" doesn't go well with all the details you have to figure out yourself when the installer doesn't do all the work.

This all makes enough sense to me. I know enough to be able to figure out what you said here and to learn a few more things along the way. Thank you very much!
