Db defaults are ok.

Write mode is not implemented (see man dnsmasq).
Read mode works: all files inside the tftp directory must be owned by nobody user.

Also successfully tested pxe boot, follow below instructions to reproduce.

Before release, please add:
  • developer manual page
  • administrator manual page (also add instructions about pxe boot)

PXE boot server

The following instructions will create a PXE server to boot a CentOS.

yum install syslinux
cp /usr/share/syslinux/{pxelinux.0,menu.c32,memdisk,mboot.c32,chain.c32} /var/lib/tftpboot/
config setprop tftp dhcp-boot pxelinux.0
signal-event nethserver-tftp-save
mkdir /var/lib/tftpboot/pxelinux.cfg

Create the file /var/lib/tftpboot/pxelinux.cfg/default with the following content:

default menu.c32
prompt 0
timeout 300

MENU TITLE PXE Menu

LABEL CentOS
  kernel CentOS/vmlinuz
  append initrd=CentOS/initrd.img

Create a CentOS directory:

mkdir -p /var/lib/tftpboot/CentOS

Copy inside the directory vmlinuz and initrd.img files.
These files can be found inside the ISO or browsing the yum os mirror.
