[atomic-devel] Proposal for default qcow2 image virtual size 10G instead of 6G

[Vivek Goyal <vgoyal redhat com>]

Hi,

Virtual size of qcow2 f22 atomic size is 6G. I am wondering if there is
a reason behind such small size. Will 10G be a better default.

Right now out of 6G, 3G is consumed by rootfs. We also setup thin pool
for docker which will consume 40% of free space (or 2G minimum). Some
people are finding that out of box, there is not enough space for thin
pool and 3G free space gets exhausted pretty fast.

Is it a good idea to bump up default virtual size to 10G?

Thanks
Vivek
