Password prompt for /etc/hosts setup is confusing

Password prompt for /etc/hosts setup is confusing

Problem

During obolup.sh, users are prompted for a password to add obol.stack to /etc/hosts. The current wording is unclear:

[!] Administrator privileges required to update /etc/hosts

Please enter your password when prompted to add:
  127.0.0.1 obol.stack

Issues:

1. Doesn't clearly state this is the system/sudo password (not a new password being created)
2. Doesn't explain why we need it (to modify the protected /etc/hosts file)
3. Users may be confused about what password to enter

Current Code

obolup.sh:1038-1043:

log_warn "Administrator privileges required to update /etc/hosts"
echo ""
echo "Please enter your password when prompted to add:"
echo "  $hosts_entry"
echo ""

Proposed Fix

Improve the wording to be more explicit:

log_warn "Administrator privileges required to update /etc/hosts"
echo ""
echo "You will be prompted for your system password (sudo) to add:"
echo "  $hosts_entry"
echo ""
echo "This is required to modify the protected /etc/hosts file."
echo ""

Or even simpler:

echo ""
echo "Administrator privileges required to add obol.stack to /etc/hosts"
echo ""
echo "You will be prompted for your system (sudo) password to add:"
echo "  $hosts_entry"
echo ""

Additional Context

This only affects users without passwordless sudo configured. Users with NOPASSWD sudo see:

[→] Updating /etc/hosts with existing privileges...

The confusion is specific to the password prompt scenario.

Start at obolup.sh:1038-1043 and inspect the password-prompt path for updating /etc/hosts. Clarify that the prompt requests the user's system (sudo) password and explain that it is needed to modify the protected file; verify the wording does not affect the existing passwordless-sudo message.
