bcache-tools should be added by installer if system is installed onto bcache device

Thank you for taking the time to report this bug and helping to make Ubuntu better.

I think what you're really saying here is that there is no installer support for bcache. I'd say that this would be primarily a wishlist bug in the installer that you are using, even if bcache-tools needs modifying to add a udeb. Can you please specify which install you are using, and then we can reassign the bug there?

Thanks racb. I'd asked in #ubuntu on IRC, and no-one could tell me against which package to file the bug.

The problem is with the standard graphical installer from the Ubuntu live disk image. If it is installing onto a bcache'd drive, it should install bcache-tools. I think the installer already handles LVM, encrypted and RAID setups gracefully, and it would be nice if it did the same for bcache.

Thanks for reassigning this appropriately.

Let's try ubiquity. I don't know if that's right, but I think it's closer.

Status changed to 'Confirmed' because the bug affects multiple users.

I think as mentioned in Question #246592 it would be really good to add bcache to the system partitioning part of the installer.

On my desktop I have a small 60GB SSD and a large 2TB HDD

I have my fstab set up roughly like so:

    /dev/sda SSD
        sda1 20GB /
        sda2 32GB {bcache cache device}
        sda3 8GB {swap}

    /dev/sdb HDD
        sdb1 4GB /var
        sdb2 ~2TB {bcache backing device}

   RAM
        tempfs /tmp

   bcache
        bcache0 {sda2->sdb2} /home

I feel it would be very useful if the installer could recognise bcache devices and offer to use them like other devices during install.

Extending from this, it would be great to be able to setup cache devices and backing devices and then choose where to mount the resulting bcache device.
