I am not sure if checking for / being ZFS is good enough then. Wouldn't we need to check for any file system being on ZFS to create a zpool.cache file? Aside, your triaging sounds like a good explanation and like an easy fix. Thing is, my d-i fu is non-existing. Would anyone care to help? I've prepared a _completely untested_ patch which may fix the issue but I have no idea how to test it. Note, if you are right, this bug is filed against the wrong package, we may clone and reassign it to grub-installer then. -- with kind regards, Arno Töll IRC: daemonkeeper on Freenode/OFTC GnuPG Key-ID: 0x9D80F36D
