[root at f20 ~]# df -h | grep vda
/dev/vda1       9.9G  574M  9.3G   6% /
[root at f20 ~]# yum update -y &> /dev/null
[root at f20 ~]# df -h | grep vda
/dev/vda1       9.9G  922M  8.9G  10% /
[root at f20 ~]# yum clean all &> /dev/null
[root at f20 ~]# df -h | grep vda
/dev/vda1       9.9G  767M  9.1G   8% /

Okay, I guess that's valid concerns. The 1GB limit is within reach
during an update. Still, for quick testing purposes, etc. 1GB
instances are often spun up and for cases where that's not enough
people can still start the instance with a bigger root disk and have
it auto-resized.

Also, an install size of nearly 600MB feels kinda huge. I mean the
LiveCDs are (or used to be) <=700MB and had full desktop environments
running.
