Public bug reported:
The command:
$ /bin/df -x tmpfs
should exclude all filesystems of type tmpfs. The udev filesystem
mounted at /dev is of this type:
$ stat -f /dev
File: "/dev"
ID: 0 Namelen: 255 Type: tmpfs
Block size: 4096 Fundamental block size: 4096
Blocks: Total: 4109101 Free: 4109098 Available: 4109098
Inodes: Total: 4109101 Free: 4108501
However, df still displays this filesystem:
$ df -l -x tmpfs
Filesystem 1K-blocks Used Available Use% Mounted on
...
udev 16436404 12 16436392 1% /dev
