[MultiROM] [LINUX] [How-to] Rom installers for sdcard - Nexus 7 Original Development

This is an (hopefully) updated collection of all roms (not android based, but other linux OS, like ubuntu, archlinux, fedora...) for nexus 7 (grouper and tilapia) available using the MultiROM system.
MultiROM is an amazing hack (I want to thank again its author, Tasssadar) that permits to boot different OS (multiboot) and different android roms. It starts between kernel and rom init, showing a sort of bootloader dialog to choose which system to boot.
It supports installing (and booting, of course) roms to USB drives.
To use MultiROM you need multirom installation zip , a modified TWRP recovery and kernels with kexec support. Relax, is not hard or long to do this.
More information and installation (of MultiROM, recovery and kernels) --> [ MULTIROM ]
PS: I need to specify I coded nothing, my only work was helping with issues, repacking roms, make them work. I want to say thank you to all devs are developing for Nexus 7, I'm doing this because I appreciate their work and I want MultiROM to rise. It deserves to.
HOW TO INSTALL A ROM.
Tasssadar provided also a zip template (see the [ WIKI ] for more info) that is incredibly easy to use.
To install a linux os to sdcard, you just need to download the zip and flash it like a normal update.zip.
It won't replace your internal rom, because it is going to install in /sdcard, not in /system or /data. And it WON'T wipe anything.
Remember that flashing ubuntu or android rom is DIFFERENT from flashing those zips. To flash ubuntu or another android rom you need to use MultiROM menu under ADVANCED voice in recovery (again, see wiki or multirom thread if you need more information).
ROM PACKS.
In the next post I'll share links for rom zips. If you have other zips or if you have built other zips, please share them. They will be (hopefully) added to the list. If not, please pm me. I can't read all posts.
If you want to share a zip, please try it first. I don't know if I'll be able to test everything real-time, and I don't want anyone to see his sdcard erased or strange things like this. MultiROM has a percent of risk, but nobody has lost his data till now. So please share zips consciously.

PAY ATTENTION: NEW MULTIROM CHANGED THE ROM ZIP STRUCTURE!
NEW STRUCTURE HERE.
I GUESS YOU CAN USE OLD ZIPS, BUT I CAN'T TRY AND IT'S BETTER TO USE NEW METHOD (REPACK NEEDED)
STEPS TO CREATE A NEW ROM ZIP (EASY-WAY):
* first, download the template (reworked by me)
* then, unzip the template, put the root.tar.gz and rom_info.txt inside rom folder (if you don't know what I'm talking about, read again the wiki - link above)
* edit rom name inside of scripts/extract.sh script (it's the only thing you have to edit, unless you want it to do something else, but be careful in that case)
* select the 3 folders (META-INF, rom, scripts) and zip them in a zip called <DISTRONAME>-MultiROM-Installer-<VERSION>.zip (I think it's a good standard, if you don't like simply name it another way, but I reckon that using a standard would be a very good thing)
*when the zip is finished, upload your zip somewhere (I use google drive now, but I hope I'll have my storage sometime in the future) and share the link here. I will add it to the list.
If I don't, pm me.
[EDIT] new packing method for webos available https://github.com/Tasssadar/webos_multirom_packer [/EDIT]

infos: needs an OTG keyboard or to use "sudo screen /dev/ttyACM0 115200" to connect via usb.
While you are connected you need to configure wifi. I use a script that simply uses iwconfig, wpa_supplicant.conf and dhcpcd to get a wifi connection.
The rest is up to you.
Enlightenment is preinstalled in build 20130113-2.
UBUNTU TOUCH.
infos: use MultiROM Manager app to install it.

Same thing for Bodhi. But I dont know the detales about it since I don't use it.
PS as it is now this thread feels as a start to a redundant thread to what is written in Tassadars first 3 posts in the MultiRom thread. Better if you focus on the current distros that don't have any "real" maintener here on xda.

I will add those categories later

Hi xela,
I understand the process except for creating the 'root.tar.gz' file from a compressed image (.img or .raw) file. Do you need to extract the image file to the /root folder and then recompress with a command similar to:
sudo tar --numeric-owner -zpcf root.tar.gz ./*

---

Nice Topic, i've tried your first Bodhi Zip and it seems very fast and stable to me. A few bugs, but nothing major.
I'm waiting for the new Version to finish uploading

I couldn't find out how to mount those IMG files. I thought they were ext4 fs but they aren't. I tried to use dd to flash them on a drive but failure again. So to extract rootfs I install them with standard procedure (Ubuntu) and the repack roofs to tar.gz. It could be useful to find out how to directly extract rootfs, because it's the same method used by Ubuntu. With the difference that Ubuntu uses zsync to permit fast upgrade...!

I could never get it mounted as well.... Is this why your having a delay in uploading the new bodhi release?

If you can get the files from the .img files, you really dont need the zip to install it, just creat a dir with the name for the OS, then inside create a dir called root, then inside extract the .img
For the rom_info.txt file, just make the changes needed and put them on the same dir that ../root is and restart and you should be able to boot form it.

Unfortunately we have been unable to mount/extract anything from the image although it appears it may install via the multirom/ubuntu method

I think zip solution is the best and most "standard". When I make a zip I know it will work, because it's the final, multiROM surely compatible, version. And I can test it immediately, fix it, reflash, and try without messing the world up. I think update zips are the most user-friendly way too. But that's only MHO.
