Hmm, this is also not what dpkg will generate when creating md5sums itself, when the packages does not ship one. Also debsums does not seem like it handles this weird GNU-specific escaping extension. I've checked around and other md5sum implementations do not support this, for example FreeBSD, NetBSD nor Mac OS X. In addition the GNU md5sum --tag option generates BSD-style output with escaped content which is not understood by the BSD implementations! The upcoming dpkg-gendigests command will also not generate those escaped entries, so IMO debhelper should be fixed to either strip them, switch to a pure perl implementation, or wait a bit and use the upcoming dpkg-gendigests command. Meanwhile you could strip them in the open-vm-tools package debian/rules file. Thanks, Guillem
