Gentoo on a Nexus One?

Does anyone have any idea how to install Gentoo on a Nexus One? It boots off kernel 2.6.29. There is a way to run commands on it remotely using adb, so it might be possible to just follow the handbook to some extent, but maybe someone here has some insight into its bootloader, or how to make it go from the kernel into Gentoo Linux?

If you are able to do so, post how you did it

Here is a guide on installing Debian: http://forum.xda-developers.com/showthread.php?t=622474&highlight=Debian.
I imagine that one could install Gentoo from Debian in qemu, and, assuming that everything was configured correctly, it would work on the Nexus One.
I think that the first step, though, would be to make sure that the Debian installation works before trying anything else.

You could get Gentoo on a chroot...

Any idea what filesystems Android supports? I unsucessfully unpacked a stage 3 onto my fat32 SD card and it wouln't chroot because of missing the ability to set RWX permissions.

I've thought about partitioning the card but I don't know if android natively supports ext2/3/4.

You can get a kernel with ext3/4 or build your own with whatever fs you want.

Has anyone gotten this to work yet? I'm in the middle of it, and just need to get a 2.6.33 or 2.6.34 kernel working... a .config would be wonderful

I have a nexus one and I would be willing to put some time into helping. Just about any custom kernel out there has a /proc/config.gz for review.

http://droidbasement.com/db-blog/ for example

Yes, but it is for 2.6.29. I need .33 or .34 (802.11s). I'm not picking something right, 'cause "make oldconfig" doesn't seem to work.

Kernel 2.6.33.3 is the first thing listed on the page.

I'm currently running the Modaco ROM with:

Linux localhost 2.6.33-msm-teknologist-0.8 #1 PREEMPT Sun Mar 28 14:29:21 CEST 2010 armv7l GNU/Linux

I would be using "fastboot" to make things happen, loading this kernel into memory, then having it use /dev/mmcblk0p3 as root (which has a standard gentoo filesystem in ext2)...would this kernel be able to load and run it?

Or are there specialized choices in your kernel config for use only with the Modaco ROM?

Also, is this a standard linux config, or is this an android .config?

I'm really after the mesh networking capabilities, which is in the standardized non-android 2.6.32 kernel or beyond.

Ok, so, I compiled 2.6.32 from android.git.kernel.org/kernel/msm.git added the android-msm-2.6.32 branch, used the mahimahi_defconfig with the exception of the ext3 (not using it), ipv6 (also not using it), and vfp (was erroring out when trying to cross-compile).

It *will* boot, however, it reboots after ~60 seconds, and does not load the sdcard as a root partition.

This is the command I use to load it into memory:

./fastboot-linux -c "root=/dev/block/mmcblk0p3 rw rootfs=ext2 init=/sbin/init rootwait noinitrd" boot gentoo/msm/arch/arm/boot/zImage

(my root partition is on the 3rd partition on the sdcard)

Here are some choice quotes from /proc/last_kmsg:

[ 0.000000] Kernel command line: board_mahimahi.disable_uart3=0 board_mahimahi.usb_h2w_sw=0 board_mahimahi.disable_sdcard=0 diag.enabled=0 board_mahimahi.debug_uart=0 smisize=0 androidboot.baseband=4.02.02.14 androidboot.cid=GOOGL001 androidboot.carrier=GOOGLE androidboot.mid=PB9910000 androidboot.keycaps=qwerty androidboot.mode=normal androidboot.serialno=HT9CXP809540 androidboot.bootloader=0.33.0012 root=/dev/block/mmcblk0p3 rw rootfs=ext2 init=/sbin/init rootwait noinitrd

So it *is* getting the command line options, it is just choosing to ignore them for some reason, and loads a ramdisk anyway.

At the end, here is what happens right before it reboots:

Any help?
