Our general thinking is that we will maintain a standard list of those,

Hey Till,
That is (as far as I know) not possible today. Those groups and users
have to exist beforehand. A similar problem also exists for LXD. There
is a bug at https://bugs.launchpad.net/snappy/+bug/1606510 which has a

OK, I have
Hi,
I want to snap CUPS and for that also to snap avahi-daemon.
A problem I am running into is that these services use special system
users and groups. avahi-daemon uses the user "avahi" and CUPS uses the
user "lp", and the groups "lp" and "lpadmin".
How can I make my snap create such users

snapweb uses a small mdns implementation written in go; avahi is much more than

Well there's a difference between using avahi and just broadcasting mDNS

CUPS is not able to broadcast shared printers by itself. It registers
them at avahi-daemon and avahi-daemon broadcasts
Hi,
I am currently snapping CUPS (both for server and for desktop/phone
printing needs) and testing it on Ubuntu Core.
Another reason to put CUPS into a snap is that one could also snap
printer drivers to have them in a distribution-independent package
format (so that manufacturers need to

Here I have found out that there is no "lpadmin" system group. Now I

Hi,
I am making a snap containing both cupsd and cups-browsed, cupsd has to
be started first, then cups-browsed, and on shutdown cups-browsed has to
stop before cupsd. cups-browsed needs a running cupsd all the time.
How do I define the correct startup/shutdown sequence?

Hi,
I have snapped cups (listening on port 10631 to not interfere with the
system's CUPS) and cups-filters into one single snap. The CUPS web
interface (http://localhost:10631/) works, one can set up print queues,
kill jobs, ...
Printing jobs also works, at least when there is no need to
