Bind mounts may cross file system boundaries and span chroot(2) jails. The filesystemtype and data arguments are ignored. Up until Linux 2.6.26, mountflags was also ignored (the bind mount has the same mount options as the underlying mount point). Since Linux 2.6.26, the MS_RDONLY flag is honored when making a bind mount. /mnt/data/home /home none bind /mnt/data/.yum-cache /var/cache/yum none bind /mnt/data/.tmp /tmp none bind /mnt/data/www/thelounge.net /Volumes/dune/www-servers none bind /mnt/data/www/phpincludes /Volumes/dune/www-servers/phpincludes none bind [root@rh:~]$ /bin/df -hT Dateisystem Typ Größe Benut Verf Ben%% Eingehängt auf rootfs rootfs 29G 8,0G 21G 28% / udev devtmpfs 7,8G 4,0K 7,8G 1% /dev tmpfs tmpfs 1,0G 196K 1,0G 1% /dev/shm tmpfs tmpfs 7,9G 572K 7,9G 1% /run /dev/md1 ext4 29G 8,0G 21G 28% / tmpfs tmpfs 7,9G 0 7,9G 0% /sys/fs/cgroup tmpfs tmpfs 7,9G 572K 7,9G 1% /var/lock tmpfs tmpfs 7,9G 572K 7,9G 1% /var/run tmpfs tmpfs 7,9G 0 7,9G 0% /media tmpfs tmpfs 150M 64K 150M 1% /var/www/sessiondata tmpfs tmpfs 5,0G 186M 4,9G 4% /var/tmp /dev/md0 ext4 485M 52M 429M 11% /boot /dev/md2 ext4 3,6T 627G 3,0T 18% /mnt/data /dev/md2 ext4 3,6T 627G 3,0T 18% /home /dev/md2 ext4 3,6T 627G 3,0T 18% /var/cache/yum /dev/md2 ext4 3,6T 627G 3,0T 18% /tmp /dev/md2 ext4 3,6T 627G 3,0T 18% /Volumes/dune/www-servers /dev/md2 ext4 3,6T 627G 3,0T 18% /Volumes/dune/www-servers/phpincludes
