Can't Compile Rust In Landrun

[zicklag]

Hey there, and thanks so much for this!

I love how simple it is, and it's such a great use of kernel features.

I'm running into an issue right now where, without --unrestricted-filesystem access, I can't compile a Rust program.

$ cargo new landrun-example
$ cd landrun-example
$ echo 'rand_core = "*"' >> Cargo.toml
$ cargo fetch
$ landrun --rwx / --env PATH --env HOME cargo b
   Compiling rand_core v0.10.1
error: failed to write /home/zicklag/tmp/landrun-example/target/debug/deps/librand_core-6d3ef1b0cc4019b4.rmeta: Invalid cross-device link (os error 18)

error: could not compile `rand_core` (lib) due to 1 previous error

Any hints?

I just tested that just creating a link into a different folder fails in the sandbox:

$ ln file.txt target/link.txt
ln: failed to create hard link 'target/link.txt' => 'file.txt': Invalid cross-device link

Can you confirm you're using >= 5.19.
