I think there's a bit of confusion about the terminology.
We have:
- small first stage loader ("kboot-stage1")
- the full Linux system(s) we normally boot
- a reduced Linux system that implements extended boot loader
functionality (selection of other kernels, user input, etc.)
What I'm talking about is the latter. Petitboot is just a Linux
program that implements a good-looking GUI already designed for
this kind of boot loader. Using it just means one DIY item less
for us.

read some mails that make me not sure the kboot work process.so i
write down my think
tell me is it wrong.
--------------------------------------------------------------------------
boot process
1. update mode (i mean update normal kernel and rootfs)
(kboot-stage1)------->(kboot's kernel + kboot's
rootfs)-------->(normal kernel + normal rootfs)
^
|
then we can update normal kernel and rootfs or do some other things at here
2. phone mode (i mean normal boot the phone)
(kboot-stage1)-----|--->(normal kernel + normal rootfs (NAND)
or|--->(boot from SD
card) this is most time we use the phone.

Oh, since we're searching for names anyway, how about calling the
first-stage loader ("kboot-stage1") "figleaf" for it's the one that
hides all the bits of the system that may disturb the sensitive ?
Then we only need a new name for "kboot".
then the first-stage have a name "figleaf" ?
