[12:20] <juliank> I actually don't understand why snapd writes to /etc/systemd when it could be a generator, writing to /run/systemd
[16:43] <ogra> juliank, for what exacly ? if you mean for all the snaps, that might become a very long boot if the generator has to create all mount units and service units for all snaps installed ...
[16:45] <juliank> ogra: I don't know if it would really take a long time, one could cache them in /var/cache and copy them over too
[16:45] <juliank> Basically /etc should not be written to IMO, that's for the system administrator to touch only
[16:46] <juliank> Thinking about empty /etc, shared /usr tree for os images basically 
[16:48] <ogra> well, the /etc dir originally stems from UbuntuCore where we explicitly only make /etc/systemd writable, not sure how complex it would become to move to a generator ... (and given a boot on a single core/low ram armhf can actually already take minutes i'D be worried adding potential extra I/O time) ... but you can surely file a whishlist bug
