Route10: /cfg/post-cfg.sh does not run after a software update

Routers

Twice now a software update has been installed, and the /cfg/post-cfg.sh file has not run after the reboot. Following the reboot I have to log in to the router and manually run /cfg/post-cfg.sh.

root@GBHNKRT002:~# ls -l /cfg/post-cfg.sh
-rwxr-xr-x    1 root     root           241 Sep  5 22:14 /cfg/post-cfg.sh

root@GBHNKRT002:~# cat /cfg/post-cfg.sh
uci add network route6
uci set network.@route6[-1].interface='lan_17'
uci set network.@route6[-1].target='64:ff9b::/96'
uci set network.@route6[-1].gateway='2a02:390:5e9a:10:a6bb:6dff:fe9e:686e'
uci commit network
/etc/init.d/network reload

I think you have a timing issue. Route10 might still be setting up the network and your script tries to reload it.
