--- SIDE NOTE ---
|
||||
Ubuntu Mini Remix contains:
|
||||
- ubuntu-minimal (this is a metapackage, details at https://packages.ubuntu.com/cgi-bin/search_packages.pl?keywords=ubuntu-minimal&searchon=names&subword=1&version=all&release=all)
|
||||
- ubuntu-standard (this is a metapackage, details at https://packages.ubuntu.com/cgi-bin/search_packages.pl?keywords=ubuntu-standard&searchon=names&subword=1&version=all&release=all)
|
||||
- casper
|
||||
- lupin-casper
|
||||
|
||||
## SETUP DIR STRUCTURE
|
||||
*** buildDir is where you are maintaining the squashfs and iso bits
|
||||
|
||||
mkdir -p buildDir/iso/{casper,isolinux,install}
|
||||
## holds where squshfs goes after modding.
|
||||
## HAS ALL UNCOMPRESSED ISO BITS EXCLUDING SQUASHFS
|
||||
## OR CONTAINS DEBOOTSTRAP GENERATED DIR STRUCTURE
|
||||
mkdir buildDir/squashfs-root/
|
||||
## this is where we can extract a squashfs
|
||||
## from an iso OR generate our own from debootstrap.
|
||||
** EXTRACTING A SQUASHFS CREATES THIS
|
||||
** ONLY DO WHEN DEBOOTSTRAPING
|
||||
|
||||
## PACKAGES NEEDED PRIOR TO DOING ANYTHING
|
||||
sudo apt-get install xnest xserver-xephyr syslinux squashfs-tools genisoimage debootstrap
|
||||
## debootstrap needs to be the version you're building
|
||||
## ie, building vivid then need vivid's debootstrap
|
||||
## link above has versions to dl
|
||||
|
||||
## FOR GUI CHROOT LIKE ENVIRONMENT
|
||||
**** In a seperate terminal from build terminal
|
||||
Xnest -ac :10 -geometry 1920x1080 ## Monitor resolution
|
||||
OR
|
||||
Xephyr -resizeable -screen 1920x1080 :10

#### BUILD METHODS ####

############################
|
||||
|
||||
## BUILDING FROM AN Ubuntu-Mini-Remix
|
||||
-- DL Ubuntu-Mini-Remix [link above] and mount it
|
||||
-- copy out its contents to the iso/ dir
|
||||
GET THE HIDDEN .disk/ dir! ISO WILL FAIL OTHERWISE!!
|
||||
-- from that, copy the iso/casper/filesystem.squashfs to the same dir
|
||||
as iso/ dir
|
||||
-- unsquashfs filesystem.squashfs
|
||||
|
||||
|
||||
## BUILDING FROM AN DEBOOTSTRAP
|
||||
## same location as iso/
|
||||
sudo debootstrap --components=main,contrib,nonfree --variant=minbase --include=linux-generic,grub-pc,nano,ssh \
|
||||
--arch=amd64 bionic ./<local dir> http://archive.ubuntu.com/ubuntu/ ## URL is optional or userd for non host target types
|
||||
OR
|
||||
sudo debootstrap --arch=amd64 vivid squashfs-root/ ## For 32bit use --arch=i386

#### MAKE SQUASHFS ####
|

############################
|
||||
|
||||
If this Customised Remix is to potentially be installed on some systems then
|
||||
the /boot folder will be needed. To allow the Customised Cd to be an
|
||||
installer Cd, compress the entire chroot folder with this command:
|
||||
|
||||
## avg compression
|
||||
sudo mksquashfs squashfs-root/ iso/casper/filesystem.squashfs
|
||||
|
||||
## best compression
|
||||
sudo mksquashfs squashfs-root/ iso/casper/filesystem.squashfs -comp xz -e squashfs-root/boot
|
||||
|
||||
|
||||
Then write the filesystem.size file, which is needed by the installer:
|
||||
|
||||
sudo chmod 644 iso/casper/filesystem.size
|
||||
printf $(sudo du -sx --block-size=1 squashfs-root/ | cut -f1) > iso/casper/filesystem.size
|
||||
sudo chmod 444 iso/casper/filesystem.size
|
||||

#### Calculate MD5 ####
|
||||
############################
|
||||
|
||||
This calculates the md5sum of everything in the image folder,
|
||||
except the file named md5sum.txt.
|
||||
|
||||
sudo -s
|
||||
(cd iso && find . -type f -print0 | xargs -0 md5sum | grep -v "\./md5sum.txt" > SHA256SUMS)
|
||||
exit
