@ -3,6 +3,8 @@ livecd-rootfs (2.843) UNRELEASED; urgency=medium
* Unconditionally enable i386 in the chroot for Ubuntu Desktop; the new
installer doesn't handle enabling this at install time, and late
enablement also misses us some recommends.
* Restore losetup code, the necessary launchpad-buildd changes were being
deployed just as this revert landed.
