<p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-family:"Arial","sans-serif";color:#274E13">Here are the steps which I follow to modify my ISO for adding Kickstart, you might want to give it a try. One can run these steps on RHEL7/CentOS7
machine.<br>
<br>
1. Mount the DVD iso at some location:<br>
<br>
</span><span style="font-family:"Tahoma","sans-serif";color:#274E13"> # mount -o loop /path/to/rhel-server-7.2-x86_64-dvd.iso /mnt</span><span style="font-family:"Arial","sans-serif";color:#274E13"><br>
<br>
2. Then create a directory and copy all the contents of the ISO into the same.<br>
<br>
</span><span style="font-family:"Tahoma","sans-serif";color:#274E13"> # mkdir /tmp/rhel7<br>
# shopt -s dotglob<br>
# cp -avRf /mnt/* /tmp/rhel7</span><span style="font-family:"Arial","sans-serif";color:#274E13"><br>
<br>
3. Verify that all hidden files like .treeinfo are there in /tmp/rhel7<br>
<br>
</span><span style="font-family:"Tahoma","sans-serif";color:#274E13"> # cd /tmp/rhel7<br>
# ls -a</span><span style="font-family:"Arial","sans-serif";color:#274E13"><br>
<br>
4. Get the kickstart file and rename it to ks.cfg<br>
<br>
</span><span style="font-family:"Tahoma","sans-serif";color:#274E13"> # cd /tmp/rhel7<br>
# wget <a href="ftp://192.168.122.254/rhel7/ks.cfg">ftp://192.168.122.254/rhel7/ks.cfg</a>
</span><span style="font-family:"Arial","sans-serif";color:#274E13"><========== or simply copy your kickstart file<br>
<br>
5. Confirm the LABEL of the DVD iso.<br>
<br>
</span><span style="font-family:"Tahoma","sans-serif";color:#274E13"> # blkid /path/to/rhel-server-7.2-x86_64-dvd.iso
</span><span style="font-family:"Arial","sans-serif";color:#274E13"><br>
<br>
6. Add the stanza in /tmp/rhel7/isolinux/isolinux.cfg file as follows.<br>
<br>
</span><span style="font-family:"Tahoma","sans-serif";color:#274E13">#######################################<br>
label kickstart<br>
menu label ^Kickstart Installation of RHEL7.2<br>
kernel vmlinuz<br>
append initrd=initrd.img inst.stage2=hd:LABEL=RHEL-7.2\x20Server.x86_64 inst.ks=cdrom:/ks.cfg<br>
#######################################</span><span style="font-family:"Arial","sans-serif";color:#274E13"><br>
<br>
Make sure that the stanza has inst.stage2 and the correct label.<br>
<br>
7. Now, save the file and create the ISO as follows.<br>
<br>
</span><span style="font-family:"Tahoma","sans-serif";color:#274E13"> # mkisofs -J -T -o /tmp/rhel7test.iso -b isolinux/isolinux.bin -c isolinux/<a href="http://secure-web.cisco.com/1UMmCKqlVs5S02IVStJ2oWf5O2EAILD6pDZSIRHEYfHnX1NT0NI0br2PNX4vXs4STSwWWTwhuAANnKzx2UK3KCuZIFO4KNRwSnfrdkVhxA_i-zlra-ffDUBuKkdidpZest4x1YnWOuItfMbvoXPN6UDyGYl-hRMoCwGIuWUW39FL8x8jRlaLfyUuywEXebUncWYc_4f8qAi3_whsHnUh5pT-zL4kMrp18NTNHs4uqd3OSW2LUShL2htSsA7bva4zr/http%3A%2F%2Fboot.cat">boot.cat</a>
-no-emul-boot -boot-load-size 4 -boot-info-table -R -m TRANS.TBL -graft-points -V "RHEL-7.2 Server.x86_64" /tmp/rhel7/</span><span style="font-family:"Arial","sans-serif";color:#274E13"><br>
<br>
The ISO /tmp/rhel7test.iso will be bootable. This will be for Legacy Boot only, for UEFI boot, the procedure will be a little bit different. Just few more steps added/replaced.<o:p></o:p></span></p>
