Still the same issue, using df from a non-root account always results
in permission denied warning which messes with scripts that use df.
strace shows that even with -x debugfs or -x sysfs that df is still
probing /sys
Also, TYPE's used with -x are not listed in the man page nor shown with
--help. It seems -T should show the TYPE's acceptable to df?
> df -T /sys
Filesystem Type 1K-blocks Used Available Use% Mounted on
sysfs sysfs 0 0 0 - /sys
The above shows that the TYPE for /sys is sysfs but -x sysfs does not
ignore that tree
it seems it only suppresses printing of the results. You can see this in
the strace
