Whilst subsequent repairs yielded a file system that was marked clean, the base system remained essentially unusable.=20 Please: should I open a separate bug for this? Or is breakage a (rare but explicable) possibility with the combination of those two criteria? ---- man 8 mount > =E2=80=A6 > noasync > Metadata I/O should be done synchronously, while data I/O > should be done asynchronously.
