"Linode Images allows you to take snapshots of your disks, and then deploy them to any Linode under your account… There is no additional charge to store #Images for Linode users. Images are limited to 6GB per Image and 5 Images per account. Additionally, images can only be created on disks with ext3 or ext4 filesystems with a single partition."
Unlike Google Compute Engine (GCE) image templates / snapshots https://cloud.google.com/sdk/gcloud/reference/compute/snapshots ,
#Linode does not support #reiser4 images
