Yes, since all you need to get a preexisting bcache volume up and running is: modprobe bcache echo /dev/sdb > /sys/fs/bcache/register echo /dev/sdc > /sys/fs/bcache/register Once you do this, the bcache volume shows up in the partitioner and you can install a new Debian system pretty much as usual. Right now, even performing that first step involves unpacking the kernel image .deb, fishing out the .ko, and insmod. See also here: [1] http://atlas.evilpiepirate.org/git/linux-bcache.git/tree/Documentation/bcache.txt?h=bcache-dev This is not to say that more comprehensive bcache support in d-i wouldn't be lovely, but this is a already a very useful (and, by my estimation, easy) step. FWIW, many newer Thinkpads ship with a storage configuration where bcache is really the only sensible thing to do: A 16 GB SSD plus a large spinny disk. Andreas
