Comment 2 for bug 1554529

hm.. now i see. so in addition to having the 'snappy-ubuntu' package installed, you're wanting the cloud image and server installed image to have 'snappy install ubuntu-core' already run inside them.

Just for reference, from a cloud image today
apt-get install snappy-ubuntu: adds about 25M of usage to /

snappy install ubuntu-core: adds about 75M

a 'df -h /' on a fresh instance before versus after
/dev/vda1 20G 870M 19G 5% /
to
/dev/vda1 20G 976M 19G 5% /
