Using a normal chroot instead of a file system image #3

Closed depau closed 9 years ago

depau commented 10 years ago

I was wondering, why use an image when we can directly write stuff in /data? data is an ext4 file system, just like Arch's image, we can just chroot into it and that would do it, wouldn't it? That would solve a lot of problems, like too much allocated storage for arch or not enough space in the image...

@willcast what do you think?

I like to have it in an image because it keeps it separate from android which is the whole point of this project. My next plan is to partition /data in half and have arch on one half. I dont like the idea of mixing os together. I was also thinking of putting arch on a usb stick and boot from that. On Jul 30, 2014 7:39 AM, "Davide Depau" notifications@github.com wrote:

It's not like they are mixed together: it's still a chroot, Android's not gonna touch Arch because it's hidden by multirom (unless you're root and you mess in /data/media/0/multirom). I don't know however how to make that work with MultiROM, I guess I'll figure it out...

I created a fork of the arch install scripts that solve some issues and install arch's image into multirom by default. It does not install a kernel nor the rom_info.txt, so it needs configuration before being bootable, but chroot works out of the box. Other changes include:

hostname is now "arch-flo"
DNS is now OpenDNS
SELinux is set to permissive before chrooting into Arch and reset afterwards, as it's a pain in the ass when you build stuff from aur or try to use fakeroot.

This issue can be closed too as I added instuctions to the readme on how to do it.
