Question 8

What is fstab?

Answer 8

File System Table. If we have a file system that will be regularly mounted, we can use /etc/fstab to “register” that file system and abbreviate the mount command. If information is missing for a mount command, the system can look to /etc/fstab to “fill in the blanks”. This is most usually done with persistent file systems (like those mounted when the system is booted).

Question 9

Explain Userspace Mounting?

Answer 9

Userspace mounting on most Linux systems is handled by the udisks package. There are two versions of this: udisks and udisks2 (the newer version). For the sake of simplification, we’ll say that if your system is using udisks (version 1), it will normally mount to /media. If your system is using udisks2, it will normally mount to /run/media/USER. As we’ve seen, this userspace mounting can be done via the desktop using the mouse.
