Description:

The installation guide (wiki) claims that running 'grub-mkconfig' after installing the 'os-prober' package will detect other operating systems.

As far as I can see, 'which' isn't included in the 'base' package group, nor is it required for 'grub'.

This means that grub-mkconfig will not properly run the '30_os-prober' script under '/etc/grub.d/' (see line 33 of '30_os-prober' which assumes availability of 'which')

Additional info:
* package version(s): 2.04-2

Steps to reproduce:

1. create a fresh Arch install, pacstrap 'base', install 'grub', etc.
2. install 'os-prober'
3. mount partitions with alternate operating systems
4. run 'os-prober' manually, observe that alternate operating systems are properly detected
5. run 'grub-mkconfig', observe that alternate operating systems aren't detected

Alternatively, just uninstall 'which' on a system where alternative OSes are already in the grub config, and observe that running 'grub-mkconfig' again doesn't detect the alternative OSes.
This task depends upon
