I have released AutoDMG 1.5.3 which contains the following bugfixes:

• Include custom volume name when saving a template from the GUI.
• Fixed resolving of certain aliases on 10.10.
• Fixed error message when log file couldn’t be opened.
• Fixed building when a mobile account is roaming and can’t look up its username.

You can download 1.5.3 from the AutoDMG releases page. If you have any questions join us in ##osx-server (but please check the documentation and especially the FAQ first).
