I have a similar issue, possibly related.

My PXE syslinux menu:

LABEL 5
MENU LABEL ^Fedora 15 - x86_64 nfs-iso (interactive)
IPAPPEND 2
KERNEL FC/15/x86_64/vmlinuz
APPEND initrd=FC/15/x86_64/initrd.img ramdisk_size=5939 text repo=nfsiso:192.168.1.234:/mnt/DroboFS/Shares/build/ISO/FC/Fedora-15-x86_64-DVD.iso ksdevice=bootif ipv6=auto mtu=9000 lang=en_US.UTF-8

I get an error:

"Could't Mount ISO Source"
An Error occurred mounting the source device 192.168.1.234/mnt/DroboFS/Shares/build/ISO/Fedora-5-x86_64-DVD.iso. This may happen if your ISO images are located on an advanced storage device like LVM or RAID, or if there was a problem mounting a partition. Click exit to abort the installation.

When I press ALT+F3 I see another error msg:

INFO anaconda: moving (1) to step reposetup
ERR anaconda: couldn't mount ISO source directory: (32, 'mount.nfs: mount point /mnt/isodir is not a directory')

~~~~
When I press ALT+F2 I see a root prompt:

I'm able to see that the dir exists by typing:

  [anaconda root@localhost /]# ls -ld /mnt/isodir
  drwxr--xr-x. 2 root root - Jun 23 22:20 /mnt/isodir


When I manually attempt to NFS mount the remote ISODIR to the local /mnt/isodir

  [anaconda root@localhost /]# mount -o nolock 192.168.1.234:/mnt/DroboFS/Shares/build/ISO/FC/ /mnt/isodir

The command succeeds
  [anaconda root@localhost /]# echo $?
  0

I can see the ISO file.
  [anaconda root@localhost /]# ls -lh /mnt/isodir/Fedora-15-x86_64-DVD.iso
  -rrwxrwxrwx. 1 root root 3.4G Jun 21 23:40 /mnt/isodir/Fedora-15-x86_64-DVD.iso

When I switch into /tmp and read the /tmp/anaconda.log, here is what I see:

This seems to imply to me that specifying the DVD.iso too much information, or perhaps anaconda should be separating the dirname and basename, especially if the path ends in .iso. Anyhow, I digress... to test this implication, I then altered my syslinux PXE boot menu to remove the DVD.iso. Fully expecting an error because no DVD.iso was specified.

I got to the Same spot where the error had previously occured, time went, and went.... expecting an error any moment now. Note, I'm on the ALT+F3 screen tailling the logs.... nothing ever came for abotu a minute, AND THEN CAME:

INFO anaconda: Preparing to install packages

WTF! It worked?!?!




So here is the deal, I have a bunch of ISO images in the location I specify, so it made sense to explicitly append the FC15 dvd iso. When I flip over into ALT+F2 to examine the /tmp/anaconda.log, I see stuff about trying to download some iso files, check it out:

INFO loader transferring nfsiso:192.168.1.234:/mnt/DroboFS/Shares/build/ISO/FC//images/updates.img

and 

INFO loader transferring nfsiso:192.168.1.234:/mnt/DroboFS/Shares/build/ISO/FC//images/product.img


Both ERR.

Now the funny part is that I was attempting to install Fedora 15, but this NFSISO location contained man ISO, including my previous Fedora 14 iso.

You see where I'm going with this?

When I rebooted the login showed me Fedora release 14 (Laughlin)

I guess there is some magic to pick up the first iso, usling lexical scope rules?

I would have liked to have picked from a dialog menu which files to install from, but that is a feature request. 

The bottom line: TL;DR: is it works if we omit the file name.
