I can reliably crash a system by doing an rsync to an ntfs-3g mounted
FS. I have simply stopped doing it an have spent no time trying to
track down the problem, but maybe anyone (gnn?) working on fusefs
might want to try it.
FWIW, I can to "rsync -avn local-path/ remote-system:ntfs-3g/path"
always works. Remove the 'n' and actually move the data and it dies.
