Looks like a sledge hammer approach. I mean, implementations that are ok as a sysadmin for its own computer are not necessarily advisable to be applied by default in a Linux distribution.
Does this change survive package re-installation?
It certainly takes no effect for newly installed packages.
How to reverse this?
What kind of feature breakage is to be expected?
Are there any alternative ways to implement this?
Are there any other linux distributions implementing this so we can look at their implementation for comparison?
