| """The linux relaunch gate must compare canonical paths, not spellings. |
| |
| ``--install-root`` keeps whatever spelling the app's Hermes root had (a symlinked |
| ``~/.hermes/hermes-agent``, or ``/home`` on Fedora/ostree where it is a link to |
| ``/var/home``), while ``--relaunch-target`` comes from ``process.execPath`` / |
| ``/proc/<pid>/exe`` and is already resolved. A raw prefix compare then reads the |
| binary the rebuild just replaced as a foreign AppImage/deb and refuses to relaunch. |
| |
| Drives the real ``--self-test-gate`` entry point of ``posix.sh`` (the same one |
| ``scripts/desktop-update/repro.sh gate`` uses). |
