How to get Fedora21 minimal runing on the RaspberryPi 2.0

Raw

README.md

Fedora21 minimal on RPi-2

This guide assumes that your SD slot is available at /dev/sdb. Make sure to substitute the correct value for your own SD device (or you might wipe out one of your hard disks)!! USE AT YOUR OWN RISK

Download the experimental Fedora spin:

curl -O http://www.digitaldreamtime.co.uk/Fedora/Pi2B-Minimal-armhfp-21-5-20150211-1.img.xz

Extract the image

xz -d Pi2B-Minimal-armhfp-21-5-20150211-1.img.xz

Write the image to an SD card:

sudo dd if=Pi2B-Minimal-armhfp-21-5-20150211-1.img of=/dev/sdb bs=1M

Resize the target partition

sudo sync
sudo gparted /dev/sdb # use it to resize the partition
sudo resize2fs /dev/sdb3 # to expand the fs
sudo sync

Put that disk in your Pi

Plug it in and turn it on!

Ethernet, HDMI, and keyboard should all be working. Login with root:fedora and run initial-setup to change the root password, add user accounts, and set your timezone. Your hostname can be set with hostnamectl set-hostname --static mypi.localdomain.

Next steps? Help me figure out how to install Docker and Go!

I installed the F22 docker packages from koji http://koji.fedoraproject.org/koji/buildinfo?buildID=610075

Updated Go packages are also available: http://koji.fedoraproject.org/koji/buildinfo?buildID=612641

The packages seem to install cleanly, but SELinux isn't available, and when I try to start Docker it fails with FATA[0000] Error running DeviceCreate (CreatePool) dm_task_run failed, as described here : moby/moby#6325

I checked to see if my kernel has support for DM_THIN_PROVISIONING and found the following:

info: reading kernel config from /proc/config.gz ...

Generally Necessary:
- cgroup hierarchy: properly mounted [/sys/fs/cgroup]
- CONFIG_NAMESPACES: enabled
- CONFIG_NET_NS: enabled
- CONFIG_PID_NS: enabled
- CONFIG_IPC_NS: enabled
- CONFIG_UTS_NS: enabled
- CONFIG_DEVPTS_MULTIPLE_INSTANCES: enabled
- CONFIG_CGROUPS: enabled
- CONFIG_CGROUP_CPUACCT: enabled
- CONFIG_CGROUP_DEVICE: enabled
- CONFIG_CGROUP_FREEZER: enabled
- CONFIG_CGROUP_SCHED: enabled
- CONFIG_MACVLAN: enabled
- CONFIG_VETH: enabled
- CONFIG_BRIDGE: enabled
- CONFIG_NF_NAT_IPV4: enabled
- CONFIG_IP_NF_FILTER: enabled
- CONFIG_IP_NF_TARGET_MASQUERADE: enabled
- CONFIG_NETFILTER_XT_MATCH_ADDRTYPE: enabled
- CONFIG_NETFILTER_XT_MATCH_CONNTRACK: enabled
- CONFIG_NF_NAT: enabled
- CONFIG_NF_NAT_NEEDED: enabled
- CONFIG_POSIX_MQUEUE: enabled

Optional Features:
- CONFIG_MEMCG_SWAP: missing
- CONFIG_RESOURCE_COUNTERS: enabled
- CONFIG_CGROUP_PERF: missing
- Storage Drivers:
  - "aufs":
    - CONFIG_AUFS_FS: missing
    - CONFIG_EXT4_FS_POSIX_ACL: enabled
    - CONFIG_EXT4_FS_SECURITY: enabled
  - "btrfs":
    - CONFIG_BTRFS_FS: enabled
  - "devicemapper":
    - CONFIG_BLK_DEV_DM: enabled
    - CONFIG_DM_THIN_PROVISIONING: missing
    - CONFIG_EXT4_FS: enabled
    - CONFIG_EXT4_FS_POSIX_ACL: enabled
    - CONFIG_EXT4_FS_SECURITY: enabled
  - "overlay":
    - CONFIG_OVERLAY_FS: missing

It sounds like I may need to find an updated kernel (or find updated modules to match my current kernel), or rebuild my kernel to include CONFIG_DM_THIN_PROVISIONING (and possibly CONFIG_OVERLAY_FS as well).

STATUS UPDATE:
A partial fix for Docker support is available:
You'l need to upgrade to a newer kernel that includes modules for CONFIG_OVERLAY_FS and CONFIG_DM_THIN_PROVISIONING by running sc-cleanUpdate-testing-pi from your Pi2B:

sudo sc-cleanUpdate-testing-pi
sudo reboot

After the reboot, I was able to start the Docker daemon, and docker pull an image. But I hit another error when I attempt to docker run the container:

I'm not sure, but mountpoint for cpuset not found sounds like an issue with cgroups.

To be continued...
