When the Debian Alpha ABI becomes stale,
Q: "the netboot installer now gives the error: "No kernel
modules were found. This probably is due to a mismatch between the
kernel used by this version of the installer and the kernel version
available in the archive."
Please could the netboot images be rebuilt to be based on the new kernel?"
A: 'That will happen for the next release. In the meanwhile, as usual, you
can use daily builds:'
