The /proc filesystem is a virtual filesystem in Linux that provides access to information about the system's processes and kernel parameters. It is generally not a good idea to make permanent changes to the /proc filesystem, as these changes will not be persisted across system reboots.
If you need to make changes to the /proc filesystem that will persist across reboots, you will need to modify the appropriate configuration file or system parameter. For example, if you want to change the kernel's maximum open file descriptor limit, you can do this by modifying the value of the "fs.file-max" parameter in the /etc/sysctl.conf file.
It's also important to note that making changes to the /proc filesystem can have unintended consequences and may cause problems with your system. It's always a good idea to be careful when making changes to the /proc filesystem, and to make sure you understand the potential impacts of your changes.
