Hasn't mount_union been dead for ~forever (+/- a few years)?

Last I checked, union mounts work just fine, thank you very much. unionfs (which should have been called `translucentfs') is what doesn't work. -GAWollman -- Garrett A.

Nonono. The union filesystem ('mount -t union') is broken. Union
mounts ('mount -o union') are not.

I had /var/mail mounted with -o union from another host. My own, local, mailbox would get corrupted every once in a while -- lots of \0, some other strings. 16K in size. This is on 3.0-RELEASE, with NFSv3. The server is Solaris. -mi To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-current" in the body of the message
