Or maybe you can suggest something else? I'd prefer simple text dump of gpart configuration, but not as commands. I find myself often configure systems with more than one disk and would really like to just do the following: # gpart backup ada0 | gpart restore ada1 ada2 ada3 This also means we either not dump labels or not restore them or we have additional option which will/won't restore them. BTW. I noticed that configuring label with 'gpart modify' for existing partition doesn't trigger taste, so new label doesn't appear in /dev/gpt/. -- Pawel Jakub Dawidek http://www.wheelsystems.com pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
