[PATCH 1/1] Dockerfile: provide kernel for libguestfs-tools
The libguestfs-tools use QEMU to mount an image file. This requires a Linux kernel.
Install a kernel and make vmlinuz readable.

I'm not super happy with having to work-around Ubuntu's breakage here. I assume we can't just write the tools to do sudo ... in the case of this silliness?
At least we need to reference the Ubuntu bug I posted about the other day in the commit message.

I do not want any sudo in scripts I run on my personal machine. The very idea of libguestfs-tools is to work in user space.
The kernel is used to run QEMU.
At least we need to reference the Ubuntu bug I posted about the other day in the commit message.
It is not a bug, it is a (questionable) feature of Ubuntu. I described the reason for chmod in the code. What are you missing there?
Best regards
Heinrich

I want a link to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/759725 because yes, it's a WONTFIX bug in Ubuntu, but it's also Wrong, in the commit message. Thanks!
