Why can’t they just emulate the abi on Linux
- skissane 4y agoIBM i PASE is just running (some of) the AIX userspace on top of a radically different kernel. Same basic idea as WSL1 (as opposed to WSL2). They could have it run the Linux userspace instead, but that would be a lot of work to emulate its differences from AIX, and would break backward compatibility with existing PASE applications. It isn’t clear what the benefit of making that change would be (as of today, as opposed to back when they first developed it-we can’t change the past). What it does mean though, is IBM i PASE is reliant on AIX user space development for its own progress (if there will be any)
