Hmm. Further experimentation shows that the gdm pre-login sound is played back with whatever volume was set when the user last logged out (or rebooted). I guess the 100% volume issues are in the case of:
a) Live CD default
b) Default on an HDD based install prior to anyone logging in and changing the volume.
I do still think that:
a) The default volume shouldn't be set to 100% on the live CD or a fresh install.
b) The login screen volume shouldn't be tied to the user's most recently used volume; what if they turned it up to listen to something quiet? It should be separately configurable, or limited, or similar.
