20.04's coreutils still has the behavior described in this bug. /dev is listed as type 'udev' by df but df -x udev does not exclude it; df -x devtmpfs does.
I wonder if one way to at least resolve the confusion might be to make the code that prints the table display devtmpfs devices as 'devtmpfs'. An obvious alternative would be to make '-x udev' be handled like '-x udev -x devtmpfs'. Another alternative would be to overload '-x tmpfs' to exclude also udev and devtmpfs. It's not clear what the best solution would be. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to coreutils in Ubuntu. https://bugs.launchpad.net/bugs/1219529 Title: df -x tmpfs fails to exclude udev (/dev) Status in coreutils: New Status in coreutils package in Ubuntu: Triaged Bug description: The command: $ /bin/df -x tmpfs should exclude all filesystems of type tmpfs.
