After the kernel has been loaded during the boot process, udev will handle hardware detection. Udev is a device manager that creates device nodes and symlinks in /dev based on rules and events. It also loads kernel modules and applies persistent device names and permissions. References:

The three permissions available on posix file systems are read, write, and execute. The read permission allows the user to view the contents of a file or directory. The write permission allows the user to modify or delete a file or directory. The execute permission allows the user to run a file as a program or change into a directory. References:

The command that you would run to create an updated initial file system, if your server hardware requires additional drivers to be available for the kernel at boot up, is mkinitrd. This command will create or update the initrd file in /boot based on the current kernel and configuration files. The initrd file is an initial ramdisk image that contains the necessary drivers and tools to mount the root file system and start the boot process. References:
