fastfetch shows a disk partition twice

[Aleksanaa]

General description of bug:

If there are several bind-mount mountpoints, each of them will be shown, which doesn't make sense.

My recommendation is sort them by time (just as mount do) and only show the earliest mountpoint for a block device.

This is what fastfetch shows:

Disk (/etc/NetworkManager/system-connections): 9.80 GiB /)
Disk (/etc/nixos): 9.80 GiB / 128 GiB (7%)
Disk (/home/aleksana): 120 GiB / 320 GiB (37%)
Disk (/nix): 9.80 GiB / 128 GiB (7%)
Disk (/nix/store): 9.80 GiB / 128 GiB (7%)
Disk (/var/lib): 9.80 GiB / 128 GiB (7%)

And this is what df -hl shows:

Output of fastfetch --version:

The following contents aren't helpful since I'm using nixos.

[LinusDierheimer]

Can you please post the content of /proc/mounts?

[Aleksanaa]

Can you please post the content of /proc/mounts?

Obviously the same with the mount command output above.

And this is what matters:

/dev/mapper/nix on /nix type btrfs (rw,noatime,compress=lzo,ssd,discard,space_cache=v2,subvolid=5,subvol=/)
/dev/mapper/nix on /var/lib type btrfs (rw,noatime,compress=lzo,ssd,discard,space_cache=v2,subvolid=5,subvol=/)
/dev/mapper/nix on /nix/store type btrfs (ro,noatime,compress=lzo,ssd,discard,space_cache=v2,subvolid=5,subvol=/)
/dev/mapper/nix on /etc/NetworkManager/system-connections type btrfs (rw,noatime,compress=lzo,ssd,discard,space_cache=v2,subvolid=5,subvol=/)
/dev/mapper/nix on /etc/nixos type btrfs (rw,noatime,compress=lzo,ssd,discard,space_cache=v2,subvolid=5,subvol=/)

As you can see, I'm using tmpfs as root, and a module named impermanence bind mount my /etc/nixos, /etc/NetworkManager and /var/lib to /nix/persist/<the corresponding dir>. The /nix/store is just a bind mount nixos sets to ensure that directory is readonly.

And this list seems to be sorted by time. So what we could do is just follow its order and only show once for every block device.

Obviously the same with the mount command output above.

Its usually not exactly the same (mount sometimes adds "" and stuff like that) and since fastfetch parses the file, I need to know exactly what it has to look for.

git head should be working.

No, it's still the same.

[LinusDierheimer]

Silly me was comparing mount paths instead of device paths. This time it should work.

It works! Thanks, I'll close this issue.
