"The issue is limited though since the default custom conf is a template and has no useful value so keeping the user version works fine"
That may be so - but how is a normal user going to know that? The "do you want to use the old file or the new file" prompt is scary, because neither option is guaranteed safe. "Old file" might break the app (because it's missing essential config) and "New file" loses your customisations. You say that in this case, "old file" is safe - but how is a user to know that? They aren't told so by the UI. We need to stop gdm.conf-custom being a conffile. Surely its name implies the user can customise it, anyway? -- Custom settings should not be a conffile https://launchpad.net/bugs/53527 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
