From d20007ce91e25385d792faedc3146cbfdc34a8c5 Mon Sep 17 00:00:00 2001 From: "W. Michael Petullo" Date: Wed, 23 Sep 2020 21:42:00 -0500 Subject: [PATCH] dnsmasq: support tftp_unique_root in /etc/config/dhcp The TFTP server provided by dnsmasq supports serving a select boot image based on the client's MAC or IP address. This allows an administrator to activate this feature in /etc/config/dhcp. Here is an example /etc/config/dhcp that configures dnsmasq with --tftp-unique-root=mac: ... config dnsmasq option enable_tftp 1 option tftp_root /usr/libexec/tftpboot option tftp_unique_root mac config boot router option serveraddress 192.168.1.1 option servername tftp.example.com option filename openwrt-initramfs-kernel.bin ... With this configuration, dnsmasq will serve /usr/libexec/tftpboot/00-11-22-33-44-55/openwrt-initramfs-kernel.bin to the client with MAC address 00:11:22:33:44:55. Signed-off-by: W.
