"""Regression tests for _apply_profile_override HERMES_HOME guard (issue #22502).
|
|
|
|
When HERMES_HOME is set to the hermes root (e.g. systemd hardcodes
|
|
HERMES_HOME=/root/.hermes), _apply_profile_override must still read
|
|
active_profile and update HERMES_HOME to the profile directory.
|
|
|
|
When HERMES_HOME is already a profile directory (.../profiles/<name>),
|
|
_apply_profile_override must trust it and return without re-reading
|
|
active_profile (child-process inheritance contract).
