[Message part 1 (text/plain, inline)]

Dear tail developers,

I get this message when doing tail -f on a file which is stored on ZFS.

tail: unrecognized file system type 0x2fc12fc1 for `messages'. please
report this to bug-coreutils <at> gnu.org. reverting to polling

[I normally wouldn't report this as it's an unusual filesystem and tail
-f still works fine, but I'll do it as it asked me to :]

Best wishes,
Marius  Bjørnstad

Thank you for reporting that.  That was addressed not long ago.
Those changes will be in the upcoming coreutils-8.20 release:
[so I've marked the your auto-created issue as "done"]

  ** Improvements
    ...

    stat and tail know about ZFS, VZFS and VMHGFS.  stat -f --format=%T now
    reports the file system type, and tail -f now uses inotify for files on
    ZFS and VZFS file systems, rather than the default (for unknown file
    system types) of issuing a warning and reverting to polling.  tail -f
    still uses polling for files on VMHGFS file systems.

And I am merging the bug tickets to make tracking the history easier.
