here acts as root directory, i.e. “/” on iOS), enhancing the functionality of deb packages lot.

Let’s take an example to see the magic of “layout”.

Go back to iOSREProject, input “make clean” and “rm *.deb” in Terminal to restore the

project to the original state:

snakeninnysiMac:iosreproject snakeninny$ make clean

rm - rf ./obj

rm - rf "/Users/snakeninny/Code/iosreproject/_"

snakeninnysiMac:iosreproject snakeninny$ rm *.deb

snakeninnysiMac:iosreproject snakeninny$ ls - l

total 32

• rw-r--r-- 1 snakeninny staff 0 Dec 3 11:28 Tweak.xm


• rw-r--r-- 1 snakeninny staff 223 Dec 3 09:05 control


• rw-r--r--@ 1 snakeninny staff 175 Dec 3 09:48 iOSREProject.plist
  lrwxr-xr-x 1 snakeninny staff 11 Dec 3 09:05 theos - > /opt/theos

Then create a new “layout” folder:

snakeninnysiMac:iosreproject snakeninny$ mkdir layout

And put some random empty files under “layout”:

snakeninnysiMac:iosreproject snakeninny$ touch ./layout/1.test

snakeninnysiMac:iosreproject snakeninny$ mkdir ./layout/Developer

snakeninnysiMac:iosreproject snakeninny$ touch ./layout/Developer/2.test

snakeninnysiMac:iosreproject snakeninny$ mkdir -

p ./layout/var/mobile/Library/Preferences

snakeninnysiMac:iosreproject

snakeninny$ touch ./layout/var/mobile/Library/Preferences/3.test

At last, run “make package” to pack, then copy the deb package to iOS, and install it via

iFile. Now you can inspect files of iOSREProject in Cydia, as shown in figure 3-13.
