Yeah, that’s UK. We’ve a million streets like that, those trees in the park-looking bit opposite. I’d imagine the house with the bins is a hotel or a B&B, something like that, because otherwise it would be odd to have so many the same colour - green is compostable and black is ‘bottles and cans’ where I live, and you normally just get one of each.
Don’t know what the green stripe on the road is. Our cycle lanes don’t look like that, aren’t that colour. I’m guessing it’s some “who’s allowed to park where in London” thing, residents-only or something like that. They’re a strange bunch, Londoners.
Isn’t the default installation of Ubuntu to BTRFS? In which case, you should have an
@
subvolume with Ubuntu that’s mounted to/
, and an@home
subvolume that’s mounted to/home
.Make a new subvolume, install a new operating system into it, and choose that subvolume in the bootloader, should be able to have Ubuntu and ‘your favourite OS’ (I use Arch btw) living side-by-side with the same home directory.
