invalid information will be printed if the -t flag is specified. $ df -t ufs Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/ad0s1a 495726 139944 316124 31% / /dev/ad0s1e 253678 6438 226946 3% /tmp /dev/ad0s1f 56206340 13594248 38115586 26% /usr /dev/ad0s1d 694126 19812 618784 3% /var /dev/ad0s1d 694126 19812 618784 3% /var $ Note that the mount point which is not accessible shows up as the previous file system that was printed. The reason for this is that df -t will call statfs(2) on the pathname supplied by getfsstat(2). This is done to refresh the file system statistics in the event that a previous file system had a long delay in providing its stats. This change affects the df utility in the following ways: o Teach df has to deal with statfs(2) failing. If statfs(2) fails, fall back on the possibly stale stats provided by the initial call to getfsstat(2). o Print a warning that the fs stats could possibly be stale o Modify the man page and document this new behavior as a bug.
