[$] The beginning of a process-builder API

Li Chen, author of the spawn-template work, has released a patch series for a process-builder API for Linux, written with significant LLM assistance, aiming to provide an alternative to the classic Unix fork()/exec() pattern and potentially implement posix_spawn().

The recent discussion on "spawn templates" https://lwn.net/Articles/1076018/ raised questions about whether it was time to provide an alternative to the classic Unix fork / exec pattern for process creation. One idea that was raised there was to shift the template pattern into an interface that could be used to efficiently assemble new processes from bare cloth, without duplicating the parent process. Preferably, that interface would be able to implement posix spawn . Li Chen, the author of the spawn-template work, has now responded with a patch series https://lwn.net/ml/all/cover.1784204592.git.me@linux.beauty written with significant LLM assistance showing what a process-builder API for Linux might look like.
