Relying on bash in latest update breaks compatibility with udm-pro

[philjohn]

The latest updates which move to using bash for the check mtu script fails to run on the udm-pro as the base debian image doesn't have bash installed, only the unifi-os container does.

Ok thanks. I was testing on an SE. Will investigate tomorrow when I can get near a Pro

No worries! I've rolled back to 0.2 for now :) And small correction to my original report, the base system is Alpine, it's Unifi-OS container that's Debian based.

I believe this is now resolved and I am testing on a UDM-SE and a UDM-Pro with no adverse effects to report so far
