Multiple calls to `pack`?

[kesmit13]

Is it possible to allow multiple calls to wasi-vfs pack? We'd like to add some files to a wasm module as a "standard library", but then add other directories later on with subsequent calls. It appears as though if you do that now, you only get the result of the final call.

I think you are mapping the same directory twice. See https://github.com/kateinoigakukun/wasi-vfs/tree/main/tests/run-make/pack-twice for the multiple call example.

Hmm, I'm not having any luck with this. If I run the following, it works as expected:

# Add standard library modules
wasi-vfs pack udf-quickjs.wasm --mapdir "/app::./app" --mapdir "/lib::./lib" --output udf-quickjs.wasm

However, if I split it into two commands, I only get the first one:

# Add standard library modules
wasi-vfs pack udf-quickjs.wasm --mapdir "/lib::./lib" --output udf-quickjs.wasm

# Add customer code modules
wasi-vfs pack udf-quickjs.wasm --mapdir "/app::./app" --output udf-quickjs.wasm

Wait a second, things just got weird. If I reverse the order of the pack commands so that /app is first and /lib is second, it does work...
