One single partition for Linux versus using a partition table?

Heya folks, some people online told me I was doing partitions wrong, but I’ve been doing it this way for years. Since I’ve been doing it for years, I could be doing it in an outdated way, so I thought I should ask.

I have separate partitions for EFI, /, swap, and /home. Am I doing it wrong? Here’s how my partition table looks like:

  • FAT32: EFI
  • BTRFS: /
  • Swap: Swap
  • Ext4: /home

I set it up this way so that if I need to reinstall Linux, I can just overwrite / while preserving /home and just keep working after a new install with very few hiccups. Someone told me there’s no reason to use multiple partitions, but several times I have needed to reinstall the OS (Linux Mint) while preserving /home so this advice makes zero sense for me. But maybe it was just explained to me wrong and I really am doing it in an outdated way. I’d like to read what you say about this though.

selokichtli,

They are probably using timeshift or some advanced feature in btrfs to auto-generate snapshots so they can go back to a working state using one of them.

The way you do it is probably getting old. I say this because I do the same, but to use several distros with a shared home partition, provided I have the same GID and UID for the users. This is not recommended but only once I’ve had a problem and it was easy to solve, so I kept doing it. Installed Fedora recently with defaults in one partition and they use one fat partition (EFI), and one btrfs partition with a logical volume and some unfamiliar partitioning. I think we are maybe missing some new technologies.

If you reinstall often a separate /home makes some sense. Otherwise it’s probably pointless. I’d try to get to a point where I don’t have to reinstall my base OS and invest in an automatic backup solution.

What you’re doing is perfectly fine.

It is however more of a mitigation for bad distro installers than general good practice. If the distro installers preserved /home, you could keep it all in one partition. Because such “bad” distro installers still exist, it is good practice if you know that you might install such a distro.

If you were installing “manually” and had full control over this, I’d advocate for a single partition because it simplifies storage. Especially with the likes of btrfs you can have multiple storage locations inside one partition with decent separation between them.

mvirts,

This is the way

I don't like wasting space or having to predict how much space I'll be using two years from now, so I prefer the minimum of partitions: efi, boot, and system(luks), with a btrfs subvol for /, home, and swapfile.

what you're doing is perfectly fine. if it's what your comfortable with, there's no 'need' to change.

I think that’s a pretty common partition layout
