Install script does not check for write access to /proc

[Somebodyisnobody]

Describe the bug
Install script will fail on systemctl restart freeradius.service in the function freeradius_enable_restart() if wirte access to /proc is denied.

To Reproduce

• Deny write access to procfs
• Run install script

Expected behavior
The script should check wirte access before to make it more resilient. Just executing the script again after giving write access to /proc will fail because the directory /var/www/daloradius already exists and the first execution of the script leavs the installation in an unfinished state.

Additional context
Add any other context about the problem here.

I am using a Proxmox Virtual Environment server (PVE) with this script running in a container where the nested feature was turned off which denied access to /proc and /sys.

@Somebodyisnobody at the moment, the installation script is not supported on Debian LXC containers that do not have the nesting feature enable on a Proxmox virtualization environment.

That's no problem. My intention was only to give you feedback to have the chance improving the installation script. I fixed it for me and hopefully my problem description and solution will help others that have the same issue until you had time to enhance the script if you want.

Thank you for your feedback. If you want to push your fixes to this repository, it is actually quite simple. Have a look at the first contributions how to 😄
