A big advantage of Snap compared to other systems for distribution-independent/sandboxed/containerized packaging of applications is that one cannot only package user applications but also system daemons and utilities.

This does not only give us all the known advantages of distributing software as Snaps also for this kind of applications but also allows things like all-Snap Linux distributions or an easy and safe way for hardware manufacturers to make Linux drivers available.

In the Snap Store we see already several of such Snaps: CUPS, Network Manager, ipp-usb, Docker, LXD, avahi-daemon, Printer Applications, ...

In this workshop Till Kamppeter, leader of the [OpenPrinting](http://ww.openprinting.org/) project and with this experienced daemon snapper (CUPS, ipp-usb, Printer Applications), will show how to make Snaps of system software, especially:

- Daemons
- System users and groups
- Workaround for UDEV rules
- Patching the upstream code
- 2 daemons in 1 Snap
- ...

Needed knowledge: Basic snapping skills, or having attended the first unit, "Your app everywhere - Just in a Snap!", on this conference.
