How to customize the Linux installation screen

For changing the name “Welcome to Centos”

In the following example we are going to change “Welcome to Red Hat Enterprise Linux “

From .img to change the text:

1) copy the images folder from original dvd/cd

2) go to images folder as

cd images

3) make a directory name as :images1

4) mount the stage2.img image on images1 as

mount -o ro,loop -t squashfs stage2.img /mnt/images1

5) cd images1/usr/lib/anaconda/test.py and images1/usr/lib/anaconda/textw/1 and
images1/usr/lib/anaconda/textw/welcome_text.py change the “Centos” as your name.

6) Also change in images1/usr/lib/anaconda/textw/complete_text.py

7) make sure the permission of all the files remains same

-r--r--r-- 1 root root 19650 Jan 1 1970 text.py

[root@localhost textw]# pwd

/root/stage1/usr/lib/anaconda/textw

[root@localhost textw]# ll welcome_text.py

-r-xr-xr-x 1 root root 836 Jan 1 1970 welcome_text.py

[root@localhost textw]#

[root@localhost textw]# ll 1

-r-xr-xr-x 1 root root 836 Jan 1 1970 1

[root@localhost textw]#

-r-xr-xr-x 1 root root 836 Jan 1 1970 1

[root@localhost textw]# ll complete_text.py

-r-xr-xr-x 1 root root 1649 Jan 1 1970 complete_text.py

[root@localhost textw]#
