Thinking about standard boot, could we add a bootdev for hostfs? Then we could drop these scripts.
I have a patch in progress to migrate vexpress64 to standard boot that tries to do this. However, it's not quite ready for upstreaming. For one, there's other boot targets in this file that would need similar treatment (e.g., AFS, MEM). Would it be possible to transition these in a piece-wise manner?
Notably, we do already have fs/sandbox/host_bootdev.c. What was the original intent of this?
