debian-installer is now using the 2.6.26 kernel (the version the kernel team wants to release lenny with) and 2.6.26 has moved to testing a few days ago. As such, it's a great time to test the daily installer images to make sure our installer for lenny is in a good state. There's still time to fix bugs in the installer, but we need your feedback.
Daily images can be obtained from the debian-installer web site which also contains instructions about how to submit installation reports. I'm particularly interested in reports about installations on ARM and MIPS. If you want to test debian-installer on these architectures, please read my messages on debian-arm and debian-mips.
