OK looks like someone else also rooted the 7 G2. I did today. Not sure what the changes lonerider23 did but here are the changes I made just like for the 10 G2:
1) Converted system.img from cramfs to ext3. /system CAN be written to!
2) Gave an extra 100mb space to /system so rooted apps that need it can use it.
3) Gave system memory a boost up from 225mb to 450mb. This give more room for apps!
4) Integrated the changes Admin asked me to do to help support Arctools Market install.
