For the record the files (&deb packages) are available at:
http://www.computemode.org/dl/cmtftp-hpa/
(patch)
http://www.computemode.org/dl/cmtftpd-hpa-buildchroot/
(the chroot builder for our environment - you might have to do a bit of
tuning though)
The script bin/gen.sh is tuned for our needs but you may just replace it
by any application handling your needs.
The etc/remap files contains the rewriting rules:
8<---
xe /PXEClient/pxelinux.cfg/01-* /bin/gen.sh
--->8
This means when a client requests something matching
'/PXEClient/pxelinux.cfg/01-foobarwhatever' then the tftpd will call
'/bin/gen.sh foobarwhatever'
Now the script/application has to follow a few straightforward rules:
- get the matched part of the file path as a first argument
- output the result file on stdout
- do an 'exit 0' if no error occured
