Detect rM2 without rm2fb and fork xochitl

[danshick]

Is your feature request related to a problem? Please describe.
Users are soft bricking their tablets if they forget to install rm2fb before oxide.

Describe the solution you'd like
Detect the rM2 device type and a working rm2fb install (similar to how reStream does). If the former is true and not the latter, just fork to Xochitl as a backup measure.

Describe alternatives you've considered
There may be a better solution long term, but this quick fix can be added fairly easily in less time.

what happens if user installs oxide and then factory resets?

They'll need to SSH in to fix up their service files.

[raisjn]

they'd get locked out. i think this task is covering only half the cases and could be better to handle this at a higher level (a special file that detects if the binary for oxide is missing, as well as detects rm2fb stuff, and launches xochitl if things are out of order)

How? SSH over USB should still work no problem.

If you'd like to open up a PR that does this in a clean way I'd be open to merging it. But without a rM2, I'm not really able to make much progress on this.

[raisjn]

if someone uses ssh keys, installs oxide (disable xochitl), then factory resets, i think they can't ssh back in

there can be a wrapper that calls oxide or draft that performs both checks

They should still be able to use SSH keys I would expect. Depending on where the authorized_keys file is.

authorized_keys is usually in ~/.ssh/. i'm pretty sure the situation i outlined is possible and i'm trying to help reduce the amount of "soft bricked" tablets.
