How did you partition your disk before installing Linux? Do you regret how you set it up?
I’m looking for some real users experiences about this and I’m trying to find the best approach for my setup.
Thank you for sharing!
Just recently repartitioned my MacBook:
1 GB for EFI (vfat)
2 GB for /boot (ext4)
11 GB for swap
224 GB for / (bcachefs)
Grub cannot load a kernel off bcachefs so I need ext4 to bridge the gap. Once the kernel is loaded, it has no problem using bcachefs as root.
This is a laptop. On a desktop that can handle more drives, I would split /home onto a drive of its own.
EFI 83:boot(e4fs) 8e:lvm(e4fs) bf:zfsThis is just for /dev/sda or so, and implies non-redundant root disks because mirroring is done by the hypervisor. I’ve been 20 years doing virtualization, and I’m really starting to forget the last vestiges of my mdadm fdisk layout.
So many people in this thread have no idea why you’d want separate allocation for /home and /tmp and others. Are we missing proper mentorship?
Well played NSA…! Anyway :
fabien@debian2080ti:~$ df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/debian2080ti--vg-root 28G 25G 1.8G 94% / /dev/mapper/debian2080ti--vg-home 439G 390G 27G 94% /home /dev/sda3 1.7T 1.6T 62G 97% /media/fabien/a77cf81e-fb2c-44a7-99a3-6ca9f15815091 /dev/nvme0n1p2 456M 222M 210M 52% /boot /dev/nvme0n1p1 511M 5.9M 506M 2% /boot/efi udev 16G 0 16G 0% /dev tmpfs 3.2G 1.9M 3.2G 1% /run tmpfs 16G 168K 16G 1% /dev/shm tmpfs 5.0M 24K 5.0M 1% /run/lock tmpfs 3.2G 2.6M 3.2G 1% /run/user/1000so basically NVMe for system and
/homein .5T and HDD 2T for backups and rarely accessed files, ext4.No dual boot, no Windows. No regrets.
I have 1/3 of a 1 TB SSD for Windows, Linux and a free partition for random stuff each. With home finally on a second 2 TB SSD. This is great, so far.
I enjoy the way OpenSuse Tumbleweed set it up:

Oh I didn’t notice I didn’t include the command (twice!).
It’s
lsblkwithout any arguments.Thank you. Odd it doesnt show network attached storage (I was going to use this method to show my partitions but I have like 3 NFS drives I use for personal, med, and long term storage)
Oh yeah, because it stands for
list block devices
In 20 years of using Linux my partition scheme has always been to say yes to whatever the OS suggests.
It’s usually that way for a reason, is my thinking
whatever the OS suggests.
Ew. Then you get XFS.
Just used the default for one big partition. I used to do tedious partition configurations, but it always ended up biting me down the road more than helping. This drive is for the OS, games, and working files. I have a 16TB NAS that holds anything worth saving, so if I need to nuke the whole thing and do a reinstall, all I really end up doing is downloading a bunch of Steam games again.
This gives basically no headaches at all. I am running this schema on all my Linux devices. And swap is done using a swapfile instead of a partition. This way, you can easily increase it later on.
~500 MB for /boot and the rest is LUKS-encrypted btrfs
Defaults are usually fine for most users. People who know they are going to distro hop or need to move data later should have a separate
/home, but that’s about it until you get into special purpose installs.- 550MiB /boot (also used as esp)
- Rest for / (btrfs)
- Subvols for /home, /var/log, /var/cache, /.snapshots (snapper snaps), /swap
I just chose the automatic partition thingy ¯\_(ツ)_/¯
For my desktop, I have two disks. One is root, one is home. They are single BTRFS filesystems with automated snapshots, compressions, and a few subvolumes. Works great.
For a laptop, similar but with only a single disk/partition and FDE. Also works well.
Two separate EFI boot Partitions if you dual boot. Its not worth letting Windows know about linux. Linux chainloads to Windows boot.
In my first install I had different home and root partitions. That was a big mistake. Once set, you cannot resize them properly and you are fucked if they are not perfect for your need. In my case the root partition got to small. After some time I just reinstalled with a single partition and would do that again.
Once set, you cannot resize them properly
This is untrue.
I’ve resized and moved partitions on a remote host during a reboot – i.e. doing the change in a batch during that boot.
It’s possible, and for most other resizes it’s easy enough and worth it for the benefits. Do you want to do it daily? No. Do you want to half-ass it and not pay attention during? Also no.
For Laptops:
- 500 MB - /boot/efi
- 1 GB /boot ext2
- X GB for / with Luks2 encrypted f2fs
And don’t forget: GPT not MBR.
