Don't worry about them.

If you don't want your users always to accept the warning when 
connecting to a printer, you should configure it. :-)

It was planned, that 4.0.17 and 4.1.7 would be released last week. 
That's why I already put that versions into to the HowTo. But are 
delayed for a few days now.

The reason for at least this versions are, that they will include two 
patches for bugs I found:
1. In previous versions you have to configure the endpoint mapper, too. 
Otherwise spoolssd wouldn't start. Even if it's not a dependency. (Bug 
#10474)
2. But more serious was a bug that prevents uploading and assigning 
drivers, when spoolssd was enabled (Bug #10481).

So if you want to use spoolssd, you should wait for the next release or 
use the git version.

If you have a large number of printers, spoolssd should be an 
improvement. But before the HowTo, there was no documentation, so I 
guess nobody used it, even if it's included since 4.0. That's why it may 
still contain bugs. But it's easy to disable in the config and then you 
are back at the traditional stuff.

It would be nice if more people would try spoolssd and report their 
experiences (and possible bugs to get them fixed soon).
