WalkthroughThe installer and uninstaller scripts now add bilingual diagnostics. Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟠 High · up to The uninstall behavior can operate on another user’s Hydro configuration when root environment variables are stale, and it can report success even when the root check fails.

Return a failure code when root is required
After the informational echo calls, $? is 0, so exit $? reports success even though the script aborted. Please return a non-zero status (for example exit 1) so callers can detect the failure.
- exit $?
+ exit 1📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In install/uninstall.sh around lines 4 to 9, the script exits with "exit $?"
after printing the root-required messages which returns 0 (success); change that
to a non-zero exit (e.g., exit 1) so the script reports failure when not run as
root; simply replace "exit $?" with "exit 1" immediately after the echo lines.

Define actual_user before using it
actual_user is never assigned, so the test on Line 26 always treats it as empty, entering this block and printing misleading messages while forcibly rewriting env vars. Add actual_user=$(whoami) (as in install.sh) before the comparison.
-read -p "> " confirm;
+read -p "> " confirm;
if [ "$confirm" != "Yes, do as I say!" ];then
echo "Aborted."
exit;

In install/uninstall.sh around lines 26 to 37, actual_user is never assigned so
the if-test always treats it as empty and the script unnecessarily overwrites
environment variables; fix it by assigning actual_user=$(whoami) (same as
install.sh) immediately before the comparison, then keep the existing if [
"$actual_user" != "$USER" ] conditional and its body unchanged so the check
behaves correctly and only runs when users differ.

perhaps the wording should be optimized (?)

This is a 'script'. If you already know it will broke in some environment that you want to support, find out the most fundamental reason and fix it automatically instead of telling user what to do - likely they are going to ignore those messages. |

Normalize the root environment before using ~.
The guard can skip remediation when actual_user and USER are both root, or both are unset, even if HOME and LOGNAME are stale. Bash then expands ~ from the stale HOME, so cleanup can target another user's Hydro configuration. Initialize actual_user and validate all root-sensitive variables, or normalize the root environment unconditionally after the EUID check.
