I'm working on building updated ISOs for Red hat 7.1. I thought I had done everything correctly, but the install blew up in my face when anaconda didn't like something it saw. I've seen this before, and it is usually indicative of a bad build or burn. I wanted to review what I did, and see if someone could point out any glaring errors they might see.

I started by downloading the first 2 CDs of the installation, and put each in its own folder.
I downloaded all of the patches and carefully replaced the existing packages, making sure I placed the appropriate ones in each folder and removed the old ones.
I made sure that the hidden files were in each directory specifying disc 1 and disc 2, and I then ran:
```
/usr/lib/anaconda-runtime/genhdlist -withnumbers /home/temp/cd-1 /home/temp/cd-2
```
I looked, and saw that hdlist timestamp had been updated, indicating something happened.

I used mkisofs to create the images. I used the following commands for each from within the root directory of each CD staging area:

   CD 1: mkisofs -b images/boot.img -c boot.cat -d -J -L -N -o
/home/image-1.iso -r -T -v ./
   CD 2: mkisofs -d -J -L -N -o /home/image-2.iso -r -T -v ./

The images were created, and then I used EZ CD Creator to burn out the images. I've not had a problem doing this before, so I believe the steps I've followed are accurate. It's been a while since I last did this, so I may have missed something.

Questions:

Someone on this list mentioned about downloading the latest images to address the SCSI adapters I use. I looked on both ftp.redhat.com and updates.redhat.com and could not find any new images other than the ones first released. Are these hidden somewhere, or is this the only image currently available?

Red Hat released respin ISOs for Red Hat 7.0. Has Red hat done the same with 7.1 or are they planning on doing this? If released, where would I download these from please?

Make sure nothing but rpms is in the RPMS directories, each rpm passes with rpm -K —nopgp —nogpg.

From the anaconda errors, you can often figure out what was wrong. What did it say?

>    /usr/lib/anaconda-runtime/genhdlist -withnumbers /home/temp/cd-1
> /home/temp/cd-2

Probably just an email typo, but you need 2 dashes in —withnumbers.

The -T option helps only old DOS systems, so I leave it out to save the space, and I remove the TRANS.TBL files to save space.

Instead of going into the directory and doing ./, I use the full pathname of the directory.

Red Hat's policy seems to be to stick to the original iso, and provide updated rpms separately, but not a new iso. This makes support easier evidently. The 7.0 respin is the only exception I know of.

Red Hat provides updated rpms, but not updated isos.
