When using bind mounts, particularly when they are specified in /etc/fstab, 'mount -a' does not recognise that a mount is already mounted and will rebind another copy over the top with each mount -a. Is this the expected behaviour? I'm not sure so I thought I'd ask. I'm using v2.20.1. Example: user@localhost ~ $ cat /etc/fstab #FILESYSTEM MOUNTPOINT TYPE OPTIONS BACKUP FSCK-PASS /root/etc /etc none bind 0 0 /root/home /home none bind 0 0 /root/local /local none bind 0 0 /root/mnt /mnt none bind 0 0 /root/tmp /tmp none bind 0 0 /root/var /var none bind 0 0 /root/swap none swap sw 0 0 user@localhost ~ $ mount rootfs on / type rootfs (rw,size=0k,nr_inodes=0) none on /dev type devtmpfs (rw,relatime,size=7202028k,nr_inodes=1800507,mode=755) none on /proc type proc (rw,relatime) none on /sys type sysfs (rw,relatime) none on /dev/pts type devpts (rw,relatime,gid=3,mode=620) none on /dev/shm type tmpfs (rw,relatime) /dev/vda on /root type ext4 (rw,relatime,user_xattr,acl,barrier=1,data=ordered) /dev/vda on /etc type ext4 (rw,relatime,user_xattr,acl,barrier=1,data=ordered) /dev/vda on /home type ext4 (rw,relatime,user_xattr,acl,barrier=1,data=ordered) /dev/vda on /local type ext4 (rw,relatime,user_xattr,acl,barrier=1,data=ordered) /dev/vda on /mnt type ext4 (rw,relatime,user_xattr,acl,barrier=1,data=ordered) /dev/vda on /tmp type ext4 (rw,relatime,user_xattr,acl,barrier=1,data=ordered) /dev/vda on /var type ext4 (rw,relatime,user_xattr,acl,barrier=1,data=ordered) user@localhost ~ $ sudo mount -a user@localhost ~ $ mount rootfs on / type rootfs (rw,size=0k,nr_inodes=0) none on /dev type devtmpfs (rw,relatime,size=7202028k,nr_inodes=1800507,mode=755) none on /proc type proc (rw,relatime) none on /sys type sysfs (rw,relatime) none on /dev/pts type devpts (rw,relatime,gid=3,mode=620) none on /dev/shm type tmpfs (rw,relatime) /dev/vda on /root type ext4 (rw,relatime,user_xattr,acl,barrier=1,data=ordered) /dev/vda on /etc type ext4 (rw,relatime,user_xattr,acl,barrier=1,data=ordered) /dev/vda on /home type ext4 (rw,relatime,user_xattr,acl,barrier=1,data=ordered) /dev/vda on /local type ext4 (rw,relatime,user_xattr,acl,barrier=1,data=ordered) /dev/vda on /mnt type ext4 (rw,relatime,user_xattr,acl,barrier=1,data=ordered) /dev/vda on /tmp type ext4 (rw,relatime,user_xattr,acl,barrier=1,data=ordered) /dev/vda on /var type ext4 (rw,relatime,user_xattr,acl,barrier=1,data=ordered) /dev/vda on /etc type ext4 (rw,relatime,user_xattr,acl,barrier=1,data=ordered) /dev/vda on /home type ext4 (rw,relatime,user_xattr,acl,barrier=1,data=ordered) /dev/vda on /local type ext4 (rw,relatime,user_xattr,acl,barrier=1,data=ordered) /dev/vda on /mnt type ext4 (rw,relatime,user_xattr,acl,barrier=1,data=ordered) /dev/vda on /tmp type ext4 (rw,relatime,user_xattr,acl,barrier=1,data=ordered) /dev/vda on /var type ext4 (rw,relatime,user_xattr,acl,barrier=1,data=ordered) -- To unsubscribe from this list: send the line "unsubscribe util-linux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
