Produce a customised ISO
![[NOTE IMPORTANT]](../graphics/note.gif)
All the commands should be entered as root
Installation of a NuTyX system
The "LFS" variable MUST be defined
In this demonstration the chroot will be in the "/ISO-NuTyX" directory, but you may choose a different name.
export LFS=/ISO-NuTyX
Make sure you have all the tools installed
If you are running a NuTyX system you can use:
cards install git cdrtools syslinux libisoburn grub-efi dosfstools
Clone the "NuTyX" git repository
Change to the directory where you want to download a temporary NuTyX repository: e.g. `cd /mnt`
git clone https://github.com/NuTyX/packages-x86_64
Install the NuTyX base system
install-nutyx
Copy necessary files for the iso
cp -av packages-x86_64/iso $LFS/ISO
Enter the chroot
install-nutyx -ec
Put the kernel and the initrd in the right place
mkinitramfs $(basename /lib/modules/*) -nf
Create a NuTyX according to your needs
About the locales
There is no need to install your own locale,
indeed the command cards upgrade will automatically install them during post-configuration.
Install DHCP service
If you not plan to install network-manager package and not want to use a static IP adress.
You want to connect to a DHCP server, you then need a dhcpcd package:
get dhcpcd
Install the EFI's installation packages
If your machine supports UEFI, it's a good idea to add the packages for the management of this one:
get efibootmgr dosfstools
Install wifi
If your machine is able to connect to a wireless network,
install at least the following packages to be able to benefit from it:
get wireless-tools wpa-supplicant
Mouse support
If you want to use the mouse in the console, install the packages:
get gpm gpm.service
Install all of the extra packages you want
get mate lightdm firefox ...
Flush the binary archives
cards purge
Generate the ISO
Generate the squashfs files
for dir in opt bin etc lib lib64 root run sbin usr var home
do
[ -f /ISO/boot/$dir.squashfs ] && rm /ISO/boot/$dir.squashfs
mksquashfs /$dir /ISO/boot/$dir.squashfs
done
Quit the NuTyX chroot
exit
Generate the ISO
bash packages-x86_64/scripts/mkiso $(basename $LFS) $(basename $LFS/lib/modules/*)
Create a bootable USB-Stick
Insert your USB-Stick and check the disk. Run:
fdisk -l
........
Disk /dev/sdb: 960.8 MiB ......
Disk model: ...
Create a bootable USB-Stick specifying the correct filename and disk (replace sdX with your USB disk)
![[Important]](../graphics/caution.gif)
Following command will remove all existing data on the USB key.
dd if=$LFS/NuTyX_x86_64-ISO-MINI.iso of=/dev/sdX status=progress
sync
Conclusion
The size should not be greater than 500 MB if you didn't add any optional packages.
You will find the iso image in the $LFS directory.
ls $LFS
bin dev home lib NuTyX_x86_64-20190626.iso proc run srv tmp var
boot etc ISO mnt NuTyX_x86_64-20190626.md5sum root sbin sys usr
