I have two Windows machines with WSL 2/Pengwin/zsh here and the first one shows prompt and refers to files and folders in Windows as /c/... but the second as /mnt/c/... for one and the same folder or file in Windows. I'm not sure which one I like better yet but surely I'd like to be able to switch between the two modes. Is this possible?
pengwin-setup made the change from /mnt/c to /c when you installed docker. This change is located in this file: /etc/wsl.conf
[automount]
**root=/**
enabled = true
options = "metadata,uid=1000,gid=1000,umask=0022,fmask=11,case=off"
mountFsTab = true
crossDistro = true
Change root=/mnt to change to the default behavior or simply delete the root line.
Restart Windows to apply the change
