[Planetlab-devel] Minimum disk size per MyPLC node

[Brett Lane]

  Is there an easy way to roll back to an older stable version, or do 
you have to re-initialize a new vserver and start from scratch? Though 
it's a not a huge deal to do this again, it'd be quite a convenience to 
be able to do so.

IIRC we came across somebody with a 16 Gb memory stick (yeah...) and made this change in a rush...
