[Fedora-livecd-list] overlay exhaustion solution ???

[John.Florian at dart.biz]

I just had interesting (or incredibly stupid) idea concerning the critical 
limitation of the live overlays where the host crashes with bus errors 
when the temporary space for the COW is exhausted.  Is it possible to use 
trim/discard support to mitigate some of the unidirectional growth for 
when files are deleted and/or overwritten?  Conceptually it seems like it 
is a good fit, but I've not investigated the practicality.  Just curious 
if this has been explored or if there are easily known reasons why this 
wouldn't work.
