Upload 'post-mount' file

[MatteoPV]

I have a DSL AC 68 U with GNUton firmware on board. Lately I've been using the VPN Failover script to handle a possible VPN drop. Everything works fine but to make everything work I added a cronjob to the post-mount file. I noticed that the post-mount file loads correctly if I do a hard restart of the modem, disconnecting the power. If I reboot from web or app, sometimes the post-mount file is not loaded in all its options ?? Why? Is it a question of timing?
