Additional information
I wanted to put bun in an embedded Linux install in which /proc wasn't mounted.
this isn't really an important bug but it would be nice to have a clear error at least.
Bun needs /proc to efficiently get the file path for open file descriptors.
What’s the rationale against mounting /proc?
There is no real reason against mounting /proc it just wasn't done on my system initially.
As I have written in additional information, it's not really important, but it would be cool to have an error message instead of a simple crash.
In Bun v0.5.0, we implemented a workaround for when /proc is not mounted. https://github.com/oven-sh/bun/commit/a345efd270bcd19672b13b363d287354113b7aba
