clear zfs properties

Default zfs properties can be read with zfs get.

root@sol11aa ~# zfs get -r quota rpool/mita
NAME              PROPERTY  VALUE  SOURCE
rpool/mita        quota     none   default
rpool/mita/jenna  quota     none   default
rpool/mita/josep  quota     none   default

These properties can be changed with zfs set.

root@sol11aa ~# zfs set quota=2gb rpool/mita/jenna
root@sol11aa ~# zfs get -r quota rpool/mita
NAME              PROPERTY  VALUE  SOURCE
rpool/mita        quota     none   default
rpool/mita/jenna  quota     2G     local
rpool/mita/josep  quota     none   default

And they can be cleared by setting the property to none, but the source is now set to local instead of default.

root@sol11aa ~# zfs set quota=none rpool/mita/jenna
root@sol11aa ~# zfs get -r quota rpool/mita
NAME              PROPERTY  VALUE  SOURCE
rpool/mita        quota     none   default
rpool/mita/jenna  quota     none   local
rpool/mita/josep  quota     none   default

This local can be restored to default using zfs inherit.

root@sol11aa ~# zfs inherit -Sr quota rpool/mita/jenna
root@sol11aa ~# zfs get -r quota rpool/mita
NAME              PROPERTY  VALUE  SOURCE
rpool/mita        quota     none   default
rpool/mita/jenna  quota     none   default
rpool/mita/josep  quota     none   default

nine provinces in Flanders ?

Radio 1 this morning discussed a proposal to split Flanders into nine provinces. Disregarding the fact that I oppose the eight layered governance of a random street(*) in my city, I would like to redraw the current map of Flanders.



One of the main issues that prevents this country from having a government resolves around (imho ridiculous) language problems in and around Brussels (the brown area). Brussels is surrounded by (officially) Dutch speaking communities, but is itself mainly French-speaking.
Bad governance between 1970 and 2010 resulted in discrepancies (for instance: French-speaking people in Dutch-speaking territory BHV can vote for French-speaking politicians, but Dutch-speaking inhabitants of the French-speaking part of Belgium cannot vote for Dutch-speaking politicians).

Also, Brussels is structurally way too small to make decisions that it should be capable of making (about its airport/highways/public transport/industry/...), since those are mainly in Dutch speaking parts outside Brussels (falling under another government).

The new map:


This new map enlarges Brussels so that it can manage the areas that currently surround Brussels but that economically and structurally belong to Brussels. Another advantage is that adding more Dutch-speaking people to Brussels makes it more balanced linguistically.
The red part is the new province of Leuven. Some municipalities from the former province of Vlaams Brabant migrated to neighboring provinces.

(*) Depending on what happens in a random Antwerp street, one or more of the following eight 'governments' is responsible:
- district (part of the city)
- gemeente (the city council)
- kanton (district, smaller than a province)
- provincie (province)
- gemeenschap (the Flemish Community)
- gewest (the Flemish Region)
- land (Belgium)
- Europese Unie (European Union)
What happened to the KISS strategy ?!
