1. What is an inode?

A way to address a group of blocks on disk, each inode contains some metadata, but does not include the name.

Each name can either be a hard link or a symlink. The inode keeps track of how many hard links there are to it. If there are 0 hard links, the inode is slated to be overwritten in the future.

blocks [1,2,3,4] <- inode <- hardlink <- symlink

This can be examined in ext4 with debugfs
