Re: [etch-users] <dependcommand></dependcommand>

Whoops, good catch on the etchserver-{demo,samples} DTD files being out of date.  The copies within test/testrepo/ in the distribution tarball are correct and I've updated the others in subversion for future releases.

Etch uses cpio extensively to move files around while preserving permissions, ownership, etc.  In order to use etch you'll need cpio installed on your clients before etch can do much of anything.

Typically this would be done by having it as a dependency of the etch package (rpm, deb, etc.)  However your question led me to notice that it wasn't listed as a dependency in the packaging files included in the distribution.  On all of our Red Hat and Debian boxes cpio was installed as part of the base installation and I hadn't thought about cases where folks excluded it.  I've added cpio as an explicit dependency for the RPM spec and Debian control files.
