Hi! Yesterday while doing research about UBI and MTD I found the nandsim module. This is a kernel module which emulates a MTD flash device. Of course this would be great to have when developing software that uses MTD.
My first question is if it is possible to run d-i without having to boot it. Use case would be to use the nandsim module (maybe from inside a chroot) "live" on my normal installation instead of having to boot the installer in, say, QEMU. Second question: If that is not possible, how do I emulate MTD with QEMU. AFAIK it is not possible with -M versatilepb, which Debian provides kernels for. This would mean that I would need a custom kernel, how does that work together with d-i? (Maybe not a problem if I don't finish the install but just quit after partition step?) Third question: What do you think about the scope of the MTD Partitioning and Installation project? Would it fill 3 months? (I think it would.) So far I propose creating partman modules: * partman-ubi * partman-auto-ubi * partman-ubifs Of course also documentation of how everything works. Suggestions on scope and/or additional tasks (that I might have missed)? As an exercise I give a draft of an implementation proposal below. Please comment wildely. For the modules scripts would be built for init.d, display.d, check.d, commit.d, finish.d etc. Example partman-ubi: * init.d -> script that recognizes MTD device(s) and loads appropriate kernel modules. * display.d -> partitioning the MTD, create data structures based on user input. (Exit code set properly, 100 for success, 255 for failure and 0 for no action performed.) * check.d -> check that partitioning scheme is ok. * commit.d -> clean MTD flash and use ubimkvol for creating UBI volume. * finish.d -> write partition scheme to fstab etc. As a ball park figure I expect that this would 3 weeks to finish. Opinions? Lastly, is there someone willing to mentor this? Best regards, Per -- To UNSUBSCRIBE, email to debian-boot-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
