macOS Startup script not working anymore in Yosemite: Need help!

[telemakos]

Hello!

I had this commands in the rc.local file (OS X Mavericks) that I need to execute in order to run my bootcamp installation (Win7) from within Virtualbox. They change the permissions and unmount bootcamp as a partition:

sudo chmod 777 /dev/disk0s4
diskutil unmount /dev/disk0s4

It seems that rc.local does not work anymore in Yosemite and now I cannot start Win7 within Virtualbox without first manually executing the above commands via terminal.
How can I automate this task at startup? I understood that "launchd" might be of help but I'm not an expert here.

Thank you!

There's more than one way of doing this. Added a few links to get you going.

Thank you!
I could finally solve the issue by using Lingon and creating 2 different plist-files.
