system.ext2
is a file containing an ext2 filesystem that XDAndroid mounts at /system
. In Android, the /system
directory generally contains files specific to a particular Android release (Eclair, Froyo, Gingerbread), including:
- the Dalvik virtual machine
- APK package files for standard apps (
Phone.apk
,Contacts.apk
,Calendar.apk
,Gmail.apk
, etc.)
system.ext2
is generated by the process described in Building and Packaging.
system.ext2
is generally stored in the /andboot/
directory of the SD card.
system.ext2
does not contain:
- the Linux kernel (
zImage
) and associated kernel modules (modules-*.tar.gz
) — those are maintained and released separately ashtc-msm-linux-date_time-package.tar.bz2
- essential UNIX utilities such as
ls
andmount
— those are provided by rootfs.img
