However, attempting to rename a file residing on a FAT file system will result in rendering that file system not unmountable. How to reproduce on a TMPFS root file system: {{{ / # cd /tmp /tmp # mkfile -s 2m image /tmp # file_bd image fbd0 /tmp # mkfat fbd0 /tmp # fat /tmp # mount fat /data fbd0 /tmp # cp /readme /data/r /tmp # mv /data/r /data/r1 /tmp # unmount /data }}} `unmount` will report EBUSY (-15)." defect closed major 0.4.3 helenos/srv/vfs fixed
