Subject: initramfs-tools: breaks building initramfs for zfs over (mirrored) LUKS - "can't find root device"

Date: Sun, 28 Jun 2015 20:58:42 +0200

Package: initramfs-tools
Version: 0.120
Severity: important

Dear Maintainer,

My first bug report - hope it's comprehensible / useful.

Trying to convert my workstation to ZFS; (kind of) following John
Goerzen's recipe. At the critical point, creating the initramfs, it
bombs out with the messages attached at the end. Have been at this for
a week now, tweaking what I can - but with no success. Please feel
free to ask for more or whatever info might be necessary. Thanks.

So far as I know, booting from zfs has never been supported in
initramfs-tools.  It would in any case require some support from one of
the zfs packages.

As zfs-linux finally entered unstable yesterday, I guess it is
time to look at this issue again.  Is this still a problem with
the packages in unstable?  What exactly is needed to reproduce it?
Should booting from zfs work, or is there something out of reach
on Linux at the moment?

I'm pretty sure it's fixed in one of my PRs that haven't been
accepted. I've seen this issue on the ZoL trackers, but I can't
remember if we got confirmation.

I include a patch for that in my ZoL packages.

https://github.com/zfsonlinux/pkg-zfs/tree/master/debian/wheezy/debian/patches

Now that ZFS have finally been accepted, we need to find
a way to merge my packages with the official Debian GNU/Linux
ones. And the Ubuntu ones.

My suggestion have been to include the debian directory into
upstream spl/zfs directly. With a little glue, we should be
able to provide ONE directory that works on everything.

My packages all work on Wheezy, Jessie, Sid as well as a
few Ubuntu versions.

This is fixed long ago, closing.
