Eventually I got fed up with Windows and decided to `zfs send` the install to a real disk and booted it on bare metal. It has been my daily driver since then for the last 2 years or so. (I did drop into the Arch installer a last year to unfuck my bootloader while trying to get rEFInd & ZFS Boot Menu to work, but that was just building a new initramfs; I haven't run "pacstrap" since I built the image c. 2013.)
The flexibility this operating system has provided me with is nothing short of amazing. I do have to say though: since switching to Wayland + the in-kernel AMDGPU driver, I can't remember the last time my system was rendered unbootable. (Excepting the one time I tried to change my bootloader, but that's user error.) In hindsight I feel like the vast majority of Arch's reputation for breaking systems is overblown, and the blame rests mostly on DKMS + NVidia's proprietary drivers.
