source: MondoRescue/branches/stable/mondo/src/common/libmondo-filelist.c@ 1224

Last change on this file since 1224 was 1224, checked in by Bruno Cornec, 17 years ago

Fix temporarily a bug when a biggiefile > 32MB was compressed below the size of a slice (16MB)
Mondo seems to not deal well when having less than a slice.
So biggiefile limit is now 64 MB to avoid that.
A better solution is to fix mondo so that it works with only one slice.
All these parameters are candidate for mondo configuration file of course.
