@sam lee, if I understand properly
you are talking about a custom Ubuntu image you created? IIRC all Ubuntu
provided default images for OpenStack/AWS after 10.04 LTS have this package
installed (or was it starting at 12.04 LTS? Scott Moser the maintainer of
the packahe might know more).
Also, from your side, I would strongly reconsider and question why you are
deploying 11.10 Ubuntu, it is not an LTS release (Long Term Support) an it
is already End of Life (a.k.a not supported anymore, see here:
you will not get
updated software not mentioning potential security issues.
A quick tip, the Ubuntu releases numbers have a meaning: 11 -> Year of
release, 10 -> Month of release. So Ubuntu 11.10 was released in October
2011, nearly 2 years ago, in the Linux word, it is legacy and the
equivalent of deploying an old Windows release. If an ISV or an specific
application forces you to do deploy this version, you should simply push
back or give further details on the use case to see if the community can
help you further.
The exact package you need installed in the instance is called "
", here is its description from the '
apt-cache show cloud-initramfs-growroot
Maintainer: Scott Moser <smoser at ubuntu.com>
Depends: cloud-utils (>= 0.21ubuntu1), initramfs-tools, util-linux (>=
Description-en: automatically resize the root partition on first boot
This package adds functionality to an initramfs built by initramfs-tools.
When installed, the initramfs will repartition a disk to make the
root volume consume all space that follows it.
You most likely do not want this package unless you know what you are
doing. It is primarily interesting in a virtualized environment when
a disk can provisioned with a size larger than its original size.
In this case, with this package installed, you can automatically use
the new space without requiring a reboot to re-read the partition table.
Hope this helps.
