I meant "any more today, now that I've looked at it to make sure the information in this posting is mostly accurate". I'll get back to them eventually, or someone else will. > Umm.

I thought I did: o Don't turn them on on the same file for different file system o Turn them off manually before you shutdown instead of having the system do it for you. o Turn them only only after you've mounted everything (again, this pretty much spells "manually"). o Put the quota file somewhere on the filesystem it applies to instead of putting them all in one handy location to guard against dev_t mixups in the code. o If all this fails, arrange it so you can live with just one file system with its quota on. > If not, who should they turn to for guidance in the lands of shadow? That would be Gandalf the puke-green. He's in an entirely different department.
