Yeah, same here. Bit a learning experience into the guts of handling filesystems. I've tended to use 'wipe' or 'dd' to scrub hard drives between systems so wouldn't have meet this bug. > I guess a more robust system would be to determine if there is ever a > need to have two different fs signatures on a single partition, and if > the answer is no, udev should print a friendly log message that it > found more than one, and please use wipefs to delete the unneeded one. Isn't udev run by the systemd mob now (with all the kludge, NIH, and "works-for-me" that brings)? Having said that, I think udev is generally pretty robust this days and this is first serious non-systemd problem I've seen in it for a long time so does look like a edge-case (although one that has occured at least twice before looking at the Debian and github bug reports). > Is there a use case to have more than one? A polymorphic filesystem which offers up the same contents as different filesystem types to different OS?
