ROM ramdisk modifications

For example CM11 ramdisk.

when you unpack cm11 boot.img, when you unpack ramdisk you will notice 2 ramdisks, one is rom ramdisk and one is recovery ramdisk (ramdisk.cpio and ramdisk.recovery.cpio). Look into previous post for CWM ramdisk modification.
Modification for ROM ramdisk (ramdisk.cpio):

init.rc file:
look for line "mkdir /system", added one line before these line: "mkdir /sde"

fstab.qcom:
the same like you done on CWM ramdisk!

init.qcom.rc:

look for lines:
Quote:
on fs
mount_all ./fstab.qcom
setprop ro.crypto.fuse_sdcard true
add:
Quote:
on fs

wait /dev/block/platform/msm_sdcc.1/by-name/userdata
mkdir /sde
mount ext4 /dev/block/platform/msm_sdcc.1/by-name/userdata /sde rw wait
exec /sbin/losetup /dev/block/loop1 /sde/media/0/bootmenu/cm11/system.ext4
exec /sbin/losetup /dev/block/loop2 /sde/media/0/bootmenu/cm11/data.ext4
exec /sbin/losetup /dev/block/loop3 /sde/media/0/bootmenu/cm11/cache.ext4
exec /sbin/e2fsck -y /dev/block/loop2
exec /sbin/e2fsck -y /dev/block/loop3

mount_all ./fstab.qcom
setprop ro.crypto.fuse_sdcard true
red line "cm11" mean that you have created cm11 folder in boot menu and use these folder for example for booting into cm11! On these "cm11" folder you have created partitons, ramdisks, kernel...etc!
