x86: fix sysupgrades on disks with 4k block size

2017-01-25T07:14:59+00:00

Even when the disk uses 4k blocks, the partition table still uses units
of 512 byte sectors. Always use ibs=512 for the offsets

x86: move sysupgrade.tgz only if it exists

2017-01-05T10:09:13+00:00

To squash error messages at boot time

    mv: can't rename '/mnt/sysupgrade.tgz': No such file or directory

x86: use sysfs DMI information to populate sysinfo

2016-06-06T13:18:11+00:00

Use the DMI data available in sysfs to extract manufacturer and model info
and write it to /tmp/sysinfo/.

The data will be picked up by board_detect and can be used by e.g. LuCI to
display a more appropriate model description.

On an APU board the files will contain the following values:

    # cat /tmp/sysinfo/model
    PC Engines APU

    # cat /tmp/sysinfo/board_name
    pc-engines-apu

x86: generalize partition discovery for sysupgrade

2016-05-24T11:30:58+00:00

Generalize the partition discovery in sysupgrade in order to fix sysupgrade
and config backup/recovery on MMC block devices which use a different naming
scheme compared to mtdblock or sd* devices.

The change also adds the find applet to the ramdisk utilities so that upgrade
code can rely on it.

The commit is based on the initial submission by Russell Senior at
http://patchwork.ozlabs.org/patch/625440/ .

x86: fix platform_export_bootpart() for Xen virtual disks

2016-04-17T13:24:30+00:00

Virtual disk devices in a Xen virtual machine (DomU) can be /dev/xvda,
/dev/xvdb and so on with partitions like /dev/xdva1. Devices named like
this where not considered before. This resulted in a non working
sysupgrade, because the boot partition could not be found.

x86: preserve partition table on sysupgrade

2016-02-09T12:33:17+00:00

With this patch sysupgrade will write directly to the partitions
instead of to the main disk.  The UUID is copied from the image
to the MBR as well.  This prevents the mbr from being completely
overwritten and losing the partition table.  The -p option has
been added to maintain the original behavior and overwite the
entire disk with the new image.  Tests have been added to ensure
that the image partitions match up with the active partitions.

x86: use PARTUUID instead explicitly specifying the device by default

2015-03-24T10:08:12+00:00

This changes the x86 image generation to match x86_64, using the PARTUUID for
the rootfs instead of explicitly configuring the device.

It unbreaks KVM with VirtIO, which uses /dev/vda2 instead of /dev/sda2.

Tested in QEMU/KVM with VirtIO, VirtualBox and VMware.
