[fedora-arm] More storage for vexpress (QEMU)

[Sean Omalley]

Seems like you should be able to dd an empty file and cat the image over a loopback interface, or maybe simply dd it. then boot and do an fdisk/resize2fs once it is booted. sort of like how you dd the image files to an sd card but to a loopback device instead. Not sure it works. :)

I do not know of an easy way to enlarge the shipped image, but it should not be difficult to make a larger image.  You would need a 'build' system (ARM platform with at least 1GB memory and sufficient external storage, i.e., disk) running F17 with anaconda and lorax installed from my xpfa repo.  The instructions are available on the wiki:

  http://fedoraproject.org/wiki/Architectures/ARM/Installer

The exact command I used for the Beta TC3 image was:

  livemedia-creator \
    --make-disk --no-virt --image-only --keep-image \
    --armplatform=None \
    --ks=./F18-ges-beta-kickstarts/F18-vexpress-xfce.ks

The kickstart file is in my git repo:

  http://fedorapeople.org/cgit/dmarlin/public_git/arm-kickstarts.git/

You would only need to change the partition layout to make the root of the image as large as necessary:

   part /boot --size 200 --fstype ext3 --label=boot
   part swap --size 500 --asprimary --label=swap
  -part / --size 2200 --fstype ext4 --label=rootfs
  +part / --size <DesiredSize> --fstype ext4 --label=rootfs


The only other option I can think of would be to manually create a disk image with the partitions sized to meet your needs, loop-mount both the shipped and new images, and then copy (rsync) the contents of the shipped image partitions to the new image partitions.

Please let me know if you have any questions.
