At least Bottles is really good and not just slop

tbh I've almost never been able to use it, on ~5 very different machines, across like 10 OSes, and dozens of images through several years. it either fails to start a VM immediately with no usable error message, or seems to run but gets stuck on a blank screen or sometimes grub, sometimes also locking up my computer. manual use of lower-level KVM stuff has worked fine on all of them, by comparison, but it's a pain so I keep trying occasionally and have only succeeded once years ago (and the next image I tried did not work, and then the working one stopped working a few days after).

so I've always been kinda confused why it's included so widely.
