changes to partition structure from #305

[dustymabe]

In #305 we switched to using reqpart --add-boot in our kickstart files.

This notably gives us an extra partition that we didn't have before and also gives us an ext4 formatted /boot partition. Before people start hardcoding in these assumptions (i.e. some early installer work POC assumes 1st partition is boot partition) we should strive to get closer to what we have laid out in the design document: https://github.com/coreos/fedora-coreos-tracker/blob/master/Design.md#summary-1

cc @ajeddeloh since you have been looking at combined bios/uefi images since that might have some implications on our final partition layout.

Please find the filesystem with LABEL=boot instead.

Please find the filesystem with LABEL=boot instead.

yeah I switched to that last night, need to add some extra logic in there just in case there is another disk attached to the system with a FS with that label, but it should work.

[ajeddeloh]

Please label both the partitions and filesystems so they can be accessed as /dev/disk/by-partlabel/foo and /dev/disk/by-label/foo.

I don't know if we every consensus on the /boot and ESP split, but it's looking more like we'll need it. Basically we're going to need:

1. /boot
2. bios-boot
3. ESP (probably to be mounted under /boot/efi or similar
4. the rootfs
5. (eventuall) /var

I don't think anaconda sets partlabels. I only see the by-partuuid directory.

[root@coreos ~]# ls -d /dev/disk/by-part*
/dev/disk/by-partuuid

This issue was mostly an FYI in case anyone noticed anything alarming that needed to be addressed. I'll close it out since there isn't really any work to be done and we can follow up on the partition structure in #334
