Which also means that for boot-strap you need to create a correct fully
populated binary dump of all the file system in the system.
A dump which is sane which regards to capabilities and user
capabilities ....

It is a little like kick-starting a database system ie writing the
system database (pg_system) into such a state that is it possible to
correctly run for example:
---
create tablespace 'stefan';
create schema 'pg';
---
and so on...
