首先，找到显示Firmware Version的代码，在/usr/lib/lua/luci/version.lua中：

BusyBox v1.36.0 (2024-04-15 02:10:29 UTC) built-in shell (ash)

root@ZWFM650:~#
root@ZWFM650:~# cat /usr/lib/lua/luci/version.lua
local pcall, dofile, _G = pcall, dofile, _G

module "luci.version"

if pcall(dofile, "/etc/openwrt_release") and _G.DISTRIB_DESCRIPTION then
distname = ""
distversion = _G.DISTRIB_DESCRIPTION
if _G.DISTRIB_REVISION then
distrevision = _G.DISTRIB_REVISION
if not distversion:find(distrevision,1,true) then
distversion = distversion .. " " .. distrevision
end
end
else
distname = "OpenWrt"
distversion = "Development Snapshot"
end

luciname = "LuCI Master"
luciversion = "git-24.102.51807-8c6da73"

root@ZWFM650:~# cat /etc/openwrt_release
DISTRIB_ID='OpenWrt'
DISTRIB_RELEASE='SNAPSHOT'
DISTRIB_TARGET='ramips/mt7621'
DISTRIB_ARCH='mipsel_24kc'
DISTRIB_TAINTS='no-all busybox'
DISTRIB_REVISION='R24.4.4'
DISTRIB_DESCRIPTION='OpenWrt '

故需要修改/etc/openwrt_release文件，查看其原本内容，可以直接在package/base-files这个package中修改此文件。

但是这样就是每次都需要重新编译base-files这个package。

最好应该是在打包文件系统时修改，这样每次打包rootfs都会重新编译。

根据打包的日志，找到执行打包的地方，在include/image.mk中，做如下修改：

diff --git a/include/image.mk b/include/image.mk
index 096ccb5..83b6ce6 100644
--- a/include/image.mk
+++ b/include/image.mk
@@ -237,6 +237,7 @@ $(eval $(foreach S,$(JFFS2_BLOCKSIZE),$(call Image/mkfs/jffs2/template,$(S))))
$(eval $(foreach S,$(NAND_BLOCKSIZE),$(call Image/mkfs/jffs2-nand/template,$(S))))

define Image/mkfs/squashfs-common
+ $(STAGING_DIR_HOST)/bin/version_maker.sh $(call mkfs_target_dir,$(1))
$(STAGING_DIR_HOST)/bin/mksquashfs4 $(call mkfs_target_dir,$(1)) $@ \
-nopad -noappend -root-owned \
-comp $(SQUASHFSCOMP) $(SQUASHFSOPT)

同时，在staging/host/bin目录下，新增脚本version_maker.sh，具体如下：

#!/bin/sh
main() {
local file=`find $1 -name openwrt_release`
# echo "file:$file"
[ ! -f $file ] && return

local D=$(TZ=UTC-8 date +%Y%m%d)
local T=$(TZ=UTC-8 date +%H%M%S)
sed -i "s/^DISTRIB_RELEASE=.*/DISTRIB_RELEASE='Adam Build $D Rel\. $T'/g" $file
sed -i "s/^DISTRIB_DESCRIPTION=.*/DISTRIB_DESCRIPTION=\'Adam Build $D Rel\. $T\'/g" $file
}

main $1

注意给文件添加可执行权限：

chmod +x version_maker.sh
然后替换对应的行即可。
