This requires calling dpkg-deb directly and pass it -z0. It reduces the time to run the mkdeb script from 14 seconds to 3 seconds on my workstation with SSD, from 87s to 15s on a machine with HDD. The deb file grows from 49M to 58M. Signed-off-by: Wei Liu <wei.liu2@citrix.com> Acked-by: Ian Jackson <ian.jackson@eu.citrix.com>

Description: Xen upstream testing build snapshot
|
|
Warning: This is a custom testing build of Xen; it is not an
|
|
officially supported Debian package. Please not distribute.
|
|
It is just the output of a xen "make dist" wrapped in a .deb
|
|
to make it easy to update and uninstall.
