Hi, I missed procfs, which has to be told the new kernel pid.
Also, I realize that these changes are a pita to build Debian packages from. You can grab the packaging bits from git://darnassus.sceen.net/teythoon/packaging/hurd.git and binary packages from deb http://darnassus.sceen.net/~teythoon/hurd-ci unstable main that include these changes. Justus
