You can't.  startrom will look for a file in the TFTP root; unless you 
rewrite the location with tftpd.rules (or the like), it needs to be in 
the TFTP root.

That said, when going down the rewrite road to have Windows pick up the 
appropriate file(s), it needs to ask for different files to begin with 
or the rewrite will cause it to pick up the same file after all.

That said, you can sed -i -e 's/winnt.sif/12345.sif/g' NTLDR to specify 
an alternative to "winnt.sif". As such, you can have profiles based on 
these three files:

startrom.n12 which points to NTDLR,
NTLDR which points to winnt.sif,
and winnt.sif

Note how the latter two contain 5 chars (excluding the .sif suffix), and 
the name of startrom.n12 really doesn't matter.

You could create a:

xp321.0 from startrom.n12,

sed -i -e 's/NTLDR/xp321/g' xp321.0

xp321 from NTLDR,

sed -i -e 's/winnt.sif/xp321.sif/g' xp321

create a xp321.sif file

Note that in this case I use Windows _XP_ _32_-bit Profile #_1_ as the 
five chars to use, but those are up to you.

bootfont.bin, ntdetwxp.x86 can just live in the TFTP root since they can 
be shared and do not refer to other files.

Now, creating a Cobbler profile or system can grab the originals, copy 
them anywhere, replace whatever they want to replace, and as such create 
"a unique" unattended installation. With unique filenames per profile 
however, you would not necessarily need to create a subdirectory in the 
TFTP root however it gets messy fast, so creating one subdirectory 
entirely managed by Cobbler probably makes the most sense, provided a 
rewrite rule for TFTP.

I'm working on some more documentation about this and more different 
Windows unattended installations over the network / using PXE on 
http://www.kanarip.com/courses/ClassRoomManual-WindowsInstallationsOverTheNetwork-WindowsXP-Steps.html

re-writing "/winnt.sif" to anything else will always cause you to 
eventually end up with the same file, just from a different location.

Modifying binaries is all you can do when all you get is binaries.

For systems (and profiles), referring to one or the other startrom.n12 
file would suffice to differentiate. The NTLDR and .sif used from that 
point can be set with a simple sed command like the few in my examples. 
This of course could also be done on-the-fly, possibly by Cobbler.

Note that for Windows XP, using the startrom.n12 from Windows 2003 is 
basically your only option or it won't ever find txtsetup.sif although 
the error message will be garbled beyond recognition.

in.tftpd does not handle links very well.
