[Spacewalk-list] Cobbler / PXE / tftp

[Waldirio Manhães Pinheiro]

Friends

I found a BZ about this case (
https://bugzilla.redhat.com/show_bug.cgi?id=872951). I really appreciate
your comments about what is the best to do, for example

- Open a BZ to change a default chroot from tftp-server to /tftpboot ?!
- Do a copy from these files (pxelinux.0 and menu.c32) to /var/lib/tftpboot
- Anything else ?!?! :-)
