I can't really answer that, sorry. It's been a *long* time since I've 
been that deep in PXE booting/TFTP, and I haven't done cobbler with 
TFTP, and I haven't used either for ESX.

I suspect that something in the ESX process is looking for the boot.cfg. 
My best guess is something in menu.

This might help:

Note these bits in particular:

# cat /mnt/boot.cfg | sed -e "s#/##g" -e "3s#^#prefix=esxi-5.1.0u1-1065491\n#" > /tftpboot/pxe/esxi-5.1.0u1-1065491/boot.cfg

and

# vi /tftpboot/pxe/pxelinux.cfg/default
default  menu.c32
prompt0
timeout300

menu title PXEBoot  Menu

labellocal
   menu label^0  -  Boot  from  first hard drive
   com32 chain.c32
   append hd0

label1
   menu label^1  -  Install  VMware  ESXi  5.1.0u1

> Why would the cobbler templates not generate the boot.cfg in the proper location if it is infact in the tftpboot directory and not in the distro directory?  I would imagine if you had more than one ESX distro you would then have collisions on the boot.cfg.  I think something else is at play here.

What happens right now when you run cobbler sync?

The top few lines of my output are:

task started: 2014-02-25_132124_sync
task started (id=Sync, time=Tue Feb 25 13:21:24 2014)
running pre-sync triggers
cleaning trees
removing: /var/lib/tftpboot/pxelinux.cfg/default
removing: /var/lib/tftpboot/grub/efidefault
removing: /var/lib/tftpboot/grub/images
removing: /var/lib/tftpboot/s390x/profile_list
copying bootloaders
copying: /usr/share/syslinux/pxelinux.0 -> /var/lib/tftpboot/pxelinux.0
copying: /usr/share/syslinux/menu.c32 -> /var/lib/tftpboot/menu.c32
copying: /usr/share/syslinux/memdisk -> /var/lib/tftpboot/memdisk
copying distros
copying images


But this is a non-production "I'm just playing with it" environment that 
I started setting up last week, so I haven't really dug into it yet, and 
since my soon to be future employer doesn't use it, it might get blown 
away.

Regards,
Petro.
