OpenWrt detection is faulty for custom builds

[adworacz]

I just ran into this bug using a custom build from Divested, which is effectively running OpenWRT HEAD with a few patches.

Looking at the AdguardHome code, it's checking for "OpenWrt" in /etc/*release.

However /etc/openwrt_release DOES exist, and contains the following:

DISTRIB_ID='Divested-WRT'
DISTRIB_RELEASE='SNAPSHOT'
DISTRIB_REVISION='r17276+9-b1bff5cb57'
DISTRIB_TARGET='mvebu/cortexa9'
DISTRIB_ARCH='arm_cortex-a9_vfpv3-d16'
DISTRIB_DESCRIPTION='Divested-WRT SNAPSHOT r17276+9-b1bff5cb57'
DISTRIB_TAINTS='no-all'

Edit: Actually /etc/os-release exists as well, and contains:

NAME="Divested-WRT"
VERSION="SNAPSHOT"
ID="divested-wrt"
ID_LIKE="lede openwrt"
PRETTY_NAME="Divested-WRT SNAPSHOT"
VERSION_ID="snapshot"
HOME_URL="https://divested.dev/unofficial-openwrt-builds/mvebu-linksys"
BUG_URL="https://github.com/divestedcg/Divested-WRT/issues"
SUPPORT_URL="xmpp:[email protected]?join"
BUILD_ID="r17276+9-b1bff5cb57"
OPENWRT_BOARD="mvebu/cortexa9"
OPENWRT_ARCH="arm_cortex-a9_vfpv3-d16"
OPENWRT_TAINTS="no-all"
OPENWRT_DEVICE_MANUFACTURER="Divested Computing Group"
OPENWRT_DEVICE_MANUFACTURER_URL="https://divested.dev"
OPENWRT_DEVICE_PRODUCT="Generic"
OPENWRT_DEVICE_REVISION="v0"
OPENWRT_RELEASE="Divested-WRT SNAPSHOT r17276+9-b1bff5cb57"

In short - the detection is looking for the "OpenWrt" string (case sensitive), while there are *release files with lowercase "openwrt" strings.

@adworacz, latest build in the edge channel should fix the issue. Could you please install it and check OpenWrt detection?

[adworacz]

Yup I’ll give it a shot this weekend!

Works like a champ!

The correct init script is installed, and the service starts correctly on reboot. Thank you for the fix!

Glad to hear that. We'll close the issue for now.
