Detailed Explanation
In Linux systems, we can mount a device in a directory using the mount command. This allows us to access the device’s filesystem
$ findmnt --real
TARGET SOURCE FSTYPE OPTIONS
/ /dev/sda5 ext4 rw,relatime,errors=remount-ro
├─/sys/kernel/tracing tracefs tracefs rw,nosuid,nodev,noexec,relatime
└─/boot/efi /dev/sda1 vfat rw,relatime,fmask=0077,dmask=0077,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro
However, we can also mount a directory on another directory by using the mount command with the --bind parameter.[1]
bind mount source can be any directory,
- If the source directory is a device’s mount point, then the whole device is bind-mounted on the destination directory.
- If instead, the source is a device’s subdirectory, then the device is bind-mounted starting from that subdirectory.
When we use the --bind parameter, mount points inside the source directory aren’t remounted. So, if we want to bind mount a directory and all submounts inside that directory, we have to use the --rbind parameter instead. After doing a bind mount, we won’t have access to the original content in the target directory. bind mount enable to access files hidden by a mount point and allows us to access files outside of chroot environment. This article shows the usage of bind mount
