💖 DESCRIPTION 💖

so xen-update-image is a simple script — and I mean genuinely simple, no drama — that lets you update a Xen image of Debian which has been created with xen-create-image. 🌈

how does she do it? she mounts the image inside a temporary directory and then runs:

apt-get update

apt-get upgrade

that's the whole ritual. mount, update, upgrade, done. periodt. 💅

⚠️ NOTE — if the image is already running within Xen, this will cause corruption. like, actually. no cap. otherwise it will allow you to update your image without booting it. so do the vibe check first and make sure it's not running, okay? 🙈

✨ EXAMPLES ✨

the following assumes there are two images which are not currently running. the images are called test.my.flat, and x11.my.flat. (cute names, honestly, slay. 🍓)

updating both images can be accomplished by executing:

xen-update-images --dir=/home/xen test.my.flat x11.my.flat

boom. two images, one command, main character energy. 👑
