[arch-general] btrfs/snapper hook for pacman 5.0?

[Elmar Stellnberger]

   However you may implement this feature please make sure that it takes 
care of the availabel disk space! Most people do only have limited space 
on their root partition and by making numerous snapshots your hard drive 
will be clobbered soon. Besides this the feature should stop 
automatically or ask for elder snapshots to be deleted before the max. 
drive fill reaches a certain percentage (f.i. 80%). As soon as your root 
partition gets filled by 100% you may not even be able to boot from it.
   Honestly thinking I can imagine there being an automatic restoration 
point for the last update only many consecutive updates being condensed 
for the same auto-restoration point on a single day, only. Anyway please 
do not leave many automatic restoration points hanging around.
