https://eklitzke.org/path-max-is-tricky https://eklitzke.org/path-max-is-tricky The Linux kernel defines upper limits for NAME_MAX (255) and PATH_MAX (4096). The glibc doesn't enforce this limit because it was originally written to run on GNU HURD which I guess doesn't have these limits. But systemd only runs on glibc on Linux. So I don't see why it doesn't at least sanity check the length of absolute paths with PATH_MAX...
