Ok, thank you for the information. I did not notice this in my tests.
I'm not sure what the "local" pseudo fs-type is meant to be used for.
Currently it appears to be identical to "not-remote" (which is what
the locate db update tries to avoid, due to high network load and
I plan to fix this within the next 24 hours (if anybody thinks it needs
to be backed-out immediately, I'm willing to do this, but I'd rather
put in the correct fix instead.
Two possibilities: We could have another pseudo fs-type in find, which
selects "real" file systems (and skips devfs, procfs, fdescfs, nullfs
and probably more). Scanning of removable devices is dubious, too,
independently of their file system. By selecting "local" and "disk
based" file systems (which would omit not only the pseudo file-systems
and nullfs, but also cd9660 and udf), no specific file systems needed
to be put into the script (and find would have the knowledge).
The second possibility is to extend the list in the update script. It
needs to contain at least:
ufs ext2fs zfs
and probably also:
xfs msdosfs ntfs ntfs-3g (?)
Did I forget any?
In fact, I'd rather enter "ufs ext2fs zfs xfs msdosfs ntfs" right now,
instead of relying on the pseudo-fs definition in find, now that I think
Any opinions or comments?

I'll fix this at the same time, but want to wait a few hours for some
