ISO build system for Rolling Rhino Remix
How to install
you need to have
cd-boot-images-amd64xorrisoaxel(optional, for faster downloads)- GNU Coreutils
next chmod +x ./fetch_build && ./fetch_build to build the entire iso.
After do sudo make clean to clean empty files.
to build a different spin of Rolling Rhino Remix, switch branches.
In detail
First fetch_build downloads a file from fetch_build.conf and names it ubuntu.iso which
is the base for all operations. Next it runs sudo make this defaults to bulding iso.
Next the stuff from makefile begins
where it firsts starts by uncompressing the iso/cd image
(ubuntu.iso from fetch_build and fetch_build.conf) to extract-cd then
uncompresses the the actual stuff you install inside of it to ./edit.
then the it prepares to go inside of that with chroot and executes
./build/build.sh inside the chroot/filesystem which prepares a bit
then executes ./build/switch.sh which changes the actual os from generic Ubuntu
After switch.sh is finished build.sh ends soon after and the makefile still
goes on. Next we move on to editing the cd image not the filesystem stuff
where the grub.cfg and loopback.cfg is copied to extract-cd and
also the filesystem is compressed to save space. Next after the disk stuff has been
defined, it is given md5 checksum to every file inside. And finally with that it is
compressed to a iso with setttings from build.conf. and last thing is a md5 of it.
How to create your own spin
the files you'll need to edit are build.conf, grub.cfg, loopback.cfg, files in ./build,
./.github/make_release.yml and maybe fetch_build.conf.
This may look intimidating but don't worry.
for loopback.cfg and grub.cfg all you have to do is edit the names from
Rolling Rhino to whatever the name of os is. Currently this will be automated in future
the fetch_build.conf is where the base iso is from and generally it uses ubiquity,
and is apt-based but doesn't have to be and generally it can be untouched most of time.
Next build.conf I think this is self explaintory but this is name of os, disk info
and the name if outputting .iso.
next the files in ./build, the build.sh is used for startup generally this is used
in the middle to remove gnome packages and stuff but it is okay if you do it in the
switch.sh which converts your install to the os. For .github/make_release.yml this
is if you want to use github runners but if not then this file isn't needed. Change
the branch your cloning and at the end for uploading artifacts section you may want to
change the name from rolling-rhino-generic.
Suggestions
If you want to create a unnoficial spin, you can create a pr and create a new branch for the spin. If you don't know how but have suggestions create a issue for your idea but know that most ideas I'd probably not want to do and maintain and thus close issue.
