When attempting an NFS installation, the installer reports No Redhat installation directory tree found. However, the installation proceeds properly when using the FTP install method.
Say your NFS server has the Red Hat tree like this: /mnt/dist/pinstripe/i386 where i386 contains all of pinstripe. Then in the installer you need to specify /mnt/dist/pinstripe/i386 as the NFS path. I know this works because its how I do all my testing - its most likely an issue like the above.
Let me elaborate a bit more. I burned the CD's, Put the CD in the drive of another Linux box, exported it (/mnt/cdrom), and tried the install. The paths I provided dirring the install was /mnt/cdrom, /mnt/cdrom/RedHat, /mnt/cdrom/RedHat/RPMS. None of them worked. This is the same way I installed RH6.2 on the same box, and it worked fine (entering /mnt/cdrom in the path). I will leave it up to you to determine if this should be reopened or not.
I have the same problem. Trying to do a NFS install on a CD-less machine. Put the CD into a RH6.2 box, mounted CD, exported CD. I can mount this cd fine via nfs on another RH box. Go to install Pinstripe and it says that it doesn't have a installation directory.
