The long term goal is to support offline download, v2rayA setup for a fresh sysupgrade of OWRT 23.05 on the Slate Plus, Beryl AX, Slate AX, Flint v1, Flint v2… using nothing more than a POSIX sh.
I’m already detecting the SOC/arch so once this is done on @GreenCat 's Flint v2, tossing some more arguments & conditional tests won’t mean much.
(We’re almost done setting up LuCI, anyway.)
