Bug Description
df appears to ignore the filesystem type "none" when specifying options on the command line. Some example output:
gecko@magina ~> df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda2 16018264 5669900 9534672 38% /
none 2020908 652 2020256 1% /dev
none 2028632 68 2028564 1% /dev/shm
none 2028632 440 2028192 1% /var/run
none 2028632 0 2028632 0% /var/lock
/dev/sdb6 457072296 42896024 390958336 10% /home
[four different "none" systems]
gecko@magina ~> df -x none
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda2 16018264 5669900 9534672 38% /
none 2020908 652 2020256 1% /dev
none 2028632 68 2028564 1% /dev/shm
none 2028632 440 2028192 1% /var/run
none 2028632 0 2028632 0% /var/lock
/dev/sdb6 457072296 42896032 390958328 10% /home
[would expect "none" systems not to appear]
gecko@magina ~> df -t none
df: no file systems processed
[would expect only "none" systems to appear]
I have no idea on whether this behaviour is intentional, however I do know that it causes a minor bug to appear in the munin package - the df plugin is unable to ignore a bunch of filesystems even though it is configured to do so by default.

Modern df lists the actual fs types for those 'none' devices. E.g. udev, tmpfs, et al. I'm guessing the reason that '-x none' was not excluding them in this old df version was because the type wasn't literally 'none' but perhaps \0 or else was just not being displayed.
In any case, I no longer am reproducing this very old bug, so am closing it out as fixed.
