For some reason, my /mnt directory was changed as owned by my user and my group with rwx------ permissions.

I have no idea why and when and how this happened, but I figured out because I mounted a disk there to install Arch on a different drive, and pacman ended up failing inside the chroot, as there were issues with permissions. Very weird.

@dmerej Thanks for confirming my lack of confidence in filesystems not native to Linux.

Actually my new drive is exFAT. I dug a bit and found Arch sees all permissions granted on every file on the drive. Also, stat -f shows the actual cluster Block size: 131072, which wastes a ton of space for things like tiny Node modules! (All the other disk info commands show 4096, which is definitely wrong!)

So I've set up a separate little EXT4 SSD for the 'systemy' parts of my backup.
