[Solved] USB pen drive install

Hi,
I was looking for the possibility of installing a full arch on an USB pen drive, but for lifetime with before boot these 4 possibilities:
1. Boot in read only mode, ALL changes just would be in ram, in this mode there is no possibility to write on this pendrive (except one partition created after install)
2. Boot in read/write mode, for updating the system or do some permanent configurations
3. Bootloader shell
4. Reboot
Thank you for incoming answers

Did you look at the wiki? [1]

Also, what is your question? I don't see one here (and the one I might be able to infer is answered with "it depends on your use case").

Re: [Solved] USB pen drive install

So, you want to create both a read only and a read/write boot entry in the bootloader? Then take a look at [1]. It lists the most used kernel parameters you can use. The rest of the article describes how to change the boot entries in your bootloader.

Re: [Solved] USB pen drive install

Yes that's exactly what I want to do, but I saw, standard is ro but it will be remount,rw after boot it seems... Secondly does that concern everything? I want that If I choose that, I don't  want ANY write accesses, no journal, no logs, nothing written to the pendrive, everything should be written in ram...

EDIT: I want it like if I would install it to an image and burn that image to a dvd...
EDIT: I saw this boot options article, but I want to know, how to boot once like if I would say to the controller of my USB drive not to allow write access. / save that in ram...  And once just normal as if I boot any system.
EDIT: is there any documentation about how to use Liveroot?

EDIT: got it thx.
