deb install aborts if membase server start fails

I am using debootstrap to create a root filesystem, the command fails on installing membase. It appears to be due to debian/postinst trying to start membase and failing.

Command used, "sudo debootstrap -arch=i386 --components=main --include=ubuntu-standard,plymouth-x11,linux-image-generic-pae,xorg,ubiquity-frontend-gtk,ubiquity-ubuntu-artwork,grub pc,dmraid,casper,tinywm,patch,monit,heartbeat,ifplugd,iftop,ntp,unzip,dialog,openssh-server,nginx,mysql-server,mysql-client,libmysqlclient16,chromium-browser,membase-server,avahi-daemon lucid lucid-rootfs http://url/to/some/repo/that/includes/membase"

http://url/to/some/repo/that/includes/membase is an custom apt repository that contains all the required debs including membase-server.

Attached is a patch that solves the problem by ignoring the startup failure, which is the approach taken by the mysql package. I haven't found where the sources for the debian package are, so my patch was created by recovering the postinst via dpkg -e.
