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 publish only one driver package,
not one per distro) and couple the driver snap to the CUPS snap as a
kind of plug-in.
As there can be any arbitrary number of different printers connected to
one machine running CUPS, it must be possible to connect any combination
of driver snaps to the installed CUPS snap, also the CUPS snap should
not be required to know which driver snaps exist. Manufacturers should
be able to publish a new driver snap at any time and every CUPS snap
user should be immediately able to use the new driver snap.
Each driver snap should provide files to CUPS, PPDs in some form (PPDs
themselves, PPD generator executable, or *.drv file), if needed, driver
executable/CUPS filter, and auxiliary files. These files are the plug of
each driver snap.
So CUPS needs to provide a slot to take these files somehow and this
slot needs to accept any printer driver snap and any number of printer
driver snaps.
Can one do this with the "content" interface? And if yes, how?
