Hi !
I didn’t know exactly where to post this so I post it here.
I had an issue installing Houdini in Garuda. I saw that I wasn’t the only one so I post here to help people that could encounter the same problem.
After installing Houdini, SideFX checks the license key with a server launching on our PC in the background. But when we install it in Garuda, the server does not launch. It is because the installer want to create the file sesinetd in the folder /etc/init.d
But by default, the folder init.d does not exist and the installer won’t create it. All you have to do is to create the folder init.d and then run the installer, then it will work !
I hope this will help some people 
PS: For people that want the command to create the folder:
sudo mkdir /etc/init.d
And the command to launch the server:
cd /etc/init.d/ && sudo ./sesinetd start
