automount not working after macOS Catalina updates

I’ve recently upgraded to macOS catalina. My automount mount for music media was broken. I fixed it and today it is again not working.

The last change I did was to install the supplemental update for 10.15.7 which seems to overwrite the /etc/auto_master so my /etc/auto_smb wasn’t loaded anymore. Here’s my current working content:

# Automounter master map
+auto_master		# Use directory service
#/net			-hosts		-nobrowse,hidefromfinder,nosuid
/home			auto_home	-nobrowse,hidefromfinder
/Network/Servers	-fstab
/-			-static
/-			auto_smb	-nosuid,noowners

Don’t forget to run

sudo automount -vc

after it you’ve changed the file. Your automount should now work again.
