Description

Description

The PhysicalDisk module does not return any physical disks on OpenBSD.

I'm running OpenBSD 7.9/amd64 on a ThinkPad T520.

OpenBSD detects the physical disk correctly:

$ sysctl hw.disknames hw.disknames=sd0:91cd4e20dbcbee82,cd0:

However, Fastfetch produces no output for the PhysicalDisk module:

$ fastfetch --structure PhysicalDisk <logo only>

The PhysicalDisk module is present in the installed Fastfetch version.

For comparison, the regular Disk module works:
$ fastfetch --structure PhysicalDisk:disk Disk (/) 130.20 MiB / 985.76 MiB (13%) - ffs Disk (/home) 944.75 MiB / 295.27 GiB (0%) - ffs Disk (/tmp) 32.00 KiB / 3.87 GiB (0%) - ffs Disk (/usr) 2.50 GiB / 29.06 GiB (9%) - ffs Disk (/usr/X11R6) 271.14 MiB / 985.76 MiB (28%) - ffs Disk (/usr/local) 3.54 GiB / 19.37 GiB (18%) - ffs Disk (/usr/obj) 2.00 KiB / 9.68 GiB (0%) - ffs Disk (/usr/src) 2.00 KiB / 4.84 GiB (0%) - ffs Disk (/var) 30.69 MiB / 11.37 GiB (0%) - ffs

Expected behavior

PhysicalDisk should detect the physical disk reported by OpenBSD as sd0, or clearly indicate that physical disk detection is unsupported on OpenBSD.

Actual behavior

PhysicalDisk produces no output.

[CarterLi]

Fastfetch does much more than sysctl hw.disknames. The cost is that it requires root.
