You can make a single file executable that does not require any dependencies with just the following. No runtime is required on the host, which I assume you allude to as lacking necessary package in the official feed might cause issues if it's required (and given it's present in everything that is not Debian, it is a Debian issue and something Debian must address).
By default targets the host's OS RID, but can be overriden with e.g. `-r linux-musl-arm64`. Cross-architecture compilation is supported within OS, and there is a nuget package that switches the publish to Zig toolchain to allow publishing for Linux under Windows without relying on WSL2: https://www.nuget.org/packages/PublishAotCross This only concerns AOT as .NET uses the same linker to produce the final binary as your regular C/C++ code. It is a true native executable through and through that is understood by all standard tooling like native code profilers. For JIT binaries, anything that .NET supports can be published for under any other OS and ISA.
* my recommendation as the size impact is negligible but codegen quality in edge cases improves quite a bit. Other flags that may be useful are -p:IlcInstructionSet=x86-x64-v3 (AVX2 and friends) and -p:IlcFoldIdenticalMethodBodies=true (it's disabled by default because it can mess up stack traces, naturally, in .NET 9, disabling stack trace information enables it as well).
