This application can install Linux Version (Actualy Debian or Ubuntu) on your phone.
The Linux is installed separetly of android, the application doesn't delete any android files.
For that the application need some preriquieres :
- Rooted phone with id 0.
- Ext2, Ext3 or Ext4 support.
- If you install into loop, LOOP is needed into kernel.
- It is recommanded to reboot your phone before lunch this app to freed your memory.
This application hold some binaries tof install Linux, for exemple, mk2fs is embarqued into my app.
If you wan't to use Ext3 or Ext4 you must format befor use my app.
I tested on my G1 this application with my custom ROM and cynogen ROM.
Debian Lenny : Works.
Debian Squeeze : In test
Ubuntu Jaunty : Works
Ubuntu Karmic can't work on G1 (CPU is not compatible).
You have 2 choices :
- Loop file
This method is easier of SD Partition, but is slower that SD Partition.
The loop file can be in 1st SD Partition (/sdcard) formatted in FAT32.
The loop file is a "hard disk" for Linux, totaly independent. You can acces to Android data, with bind mounts
Now, my recovery image can boot into a loop file
- SD partition
This is the better solution if you can partition your SD card in 2 or 3 partitions, but the 1st partition must be an FAT32 for Android data on /sdcard.
The destination partition for Linux must be moubnted before lunch my app.
My recovery image, can boot into SD partition, as root, or directory, if you can, please dedicated one partition for Linux as root.
Two tutoriel are found, and tested with default settings : Debian Lenny with ftp.debian.org download server.
For informatitions, the Debian Lenny Install Download 50M of data.

- The loop file must be in 1st SD partition.
- The 1st SD partition must do not have init file in root.
