fstab controls the read/write access of the root and media partitions. A barebones jailbreak can be put in place simply by modifying this file to grant full read/write access to the user.
Contents
Modification
The original fstab file, before a jailbreak, looks something like this:
/dev/disk0s1 / hfs ro 0 1
/dev/disk0s2 /private/var hfs rw,nosuid,nodev 0 2
Notice /dev/disk0s2 has /private/var mounted as read/write. This directory is generally where music/photos/videos/etc are stored. This directory can easily be accessed (without FULL access) with a program like PhoneDisk or DiskAid. iTunes has full and complete access to this directory, for obvious reasons. This is proven with the afc service, which iTunes uses to transfer music/videos/etc.
Summary
This file lists the partitions on all UNIX-based systems.
File Contents
- Before jailbreak:
/dev/disk0s1 / hfs ro 0 1 - After jailbreak:
/dev/disk0s1 / hfs rw 0 1
