Which partition is equal to /recovery in other android devices?

---

I am new to Android, want to customize the system follow the tutorials, but found the Note is different to other Android phones:
for other phone, there will be a /proc/mtd and list all the partitions with mount point, but on Note I can only found /proc/fs, with 3 folders: ext4 jbd2 nfsd
and the mount table is like this:

rootfs on / type rootfs (ro,relatime)
...
/dev/block/mmcblk0p9 on /system type ext4
/dev/block/mmcblk0p7 on /cache type ext4
/dev/block/mmcblk0p1 on /efs type ext4

for other devices, e.g., HTC Wildfire, the partition will like below:
mtd1: recovery
mtd3: system"
...

I downloaded the CF-Root flasher, by Chainfire, found basiclly it's flashing a zImage into /dev/block/mmcblk0p5. I mount the partition before flash and seems there is only some picture files there. how can we know the machine will boot to this partition in recovery mode?

nobody knows? so far what I get seems that the phone do not use the /recovery partition, but use same kernel to handle the recovery state. during boot it will search for /system/etc/install-recovery.sh, maybe that will trigger the recovery process?

The Note, like many other Samsung phones, does not use or follow the mtd layout - at all.

Indeed there is a single kernel for both normal boot and recovery. Normal boot uses init.rc script, recovery boot uses recovery.rc script.

There is a "spare" partition that is both called recovery and available, but it isn't used.
