Custom Fedora Installer

This set of scripts allows one to generate an ISO image with a custom set of RPMs and an automated installation script.

The generated ISO can then be restored to a USB key and perform a tailored installation of Fedora, without having to disable Secure Boot.

As a downloader

If you just want to download Fedora official ISOs, this makefile can be of use:

  • it will place the official ISO in your download folder
  • verify the ISO's integrity using the official checksum
  • verify the checksum was signed by Fedora
# To download the Workstation ISO for x86_64:
make download

# You can choose the edition and architecture:
FedoraEdition=Server Architecture=aarch64 make download

# You can even choose the installation method for the server edition:
FedoraEdition=Server Architecture=ppc64le make download FedoraMethod=dvd

# And you can choose between wget and curl
Downloader=curl make download

Downloadable status as of Fedora 40 :

Workstation Server
x86_64
aarch64
ppc64le
s390x

Generating an ISO

For conveniance, you can place all values you want to customize in a local file values.sh:

# Latest Fedora release
FedoraVersion=40-1.14

# Workstation | Server
FedoraEdition=Workstation

# x86_64 | aarch64 | ppc64le | s390x
Architecture=x86_64

# wget | curl (defaults to the first available)
# Downloader=wget

# Used to create the initial user of the OS
UserName=mname
Password=`read -s -p 'Password: ' password && openssl passwd -6 -salt SomeRandomSalt $password`
RootPassword=`read -s -p 'Root Password: ' password && openssl passwd -6 -salt SomeRandomSalt $password`

# Used to sign the bootloader (except WorldRegion that is used with City to specify the timezone)
FullName="My NAME"
[email protected]
WorldRegion=America
CountryCode=US
City=New_York

# Used during installation and on the target system
KeyboardLayouts="us,'cz (qwerty)'"
Languages=en_US
# Languages="--addsupport=en_GB en_US.utf8"
NtpPool=3.fedora.pool.ntp.org

# It is possible to override the timezone (if the City you want mentionned in the certificate is not in https://vpodzime.fedorapeople.org/timezones_list.txt)
# TimeZone=America/Toronto

Then source the file before calling make:

( set -a && source ./values.sh && make iso )

Adding a custom entry

You want an ISO that install a specific set of packages, with a tailored partitioning scheme ? You don't have to write a GRUB configuration file !

Just create a .cfg file with a name starting with entry_ in the kickstart folder, like kickstart/entry_myinstaller.cfg:

# Entry name : "Install things my way" <- Set the name of your entry as it will appear in the GRUB menu

# Include other kickstart files with this special syntax:
%shard common
# It will include kickstart/common.cfg

# And use any official kickstart command:

%packages
	@Headless-Management
	@Container-Management --optional
%end

skipx

selinux --enforcing

clearpart --all --drives=sda
partition /boot/efi           --ondisk=sda 1024
partition /     --fstype=ext4 --ondisk=sda --grow
partition /home --fstype=ext4 --ondisk=sdb --noformat --usepart=LABEL=MY_HOME

If you want this entry to be the default in GRUB, add DefaultEntry=myinstaller to values.sh.
