However it's incredibly rare and there really isn't any general procedure to do it: each country does it (or not) it's own way. This tends to be used for people caught sleeping or begging on the streets.

Further, for countries in the Schengen Area, they don't even know you're there unless you register, since you haven't passed any border controls and thus aren't in any database as having arrived but not departed.

We are in complete agreement. Like I said if you get a job in another EU country there's nothing stopping you from getting permanent residency there as well. The discussion was about moving with kids, which is the parents responsibility to figure out when it comes to cost and feasibility, but the EU will not stop them and does not impose additional barriers just because one has kids.
