Udev Detecting Partition like APFS FileSystem, Extracting Meta INFO

Previously, I made that CentOS 8 is not auto mounting my APFS partition I want to discover the partition info detecting functionality, in this operative system (*I made a new CentOS installation*) I have not installed ExFAT, neither NTFS nor APFS File Systems. The Linux kernel through daemons has managed to detect relevant information from ExFAT and NTFS without having a driver installed for it, but it has not detected the same information for APFS. I was reading. - Dynamic device management with Udev, HAL, and D-Bus - understanding-mount-option-nodev-and-its-use-with-usb-flash-drives - Mounting USB disks automatically (How it works) and read Some About of: - udev 1 , 2 , 3 - udisks 1 , 2 , 3 - dbus 1 , 2 , 3 I have a USB External SSD with 4 disk partitions. The file system of partitions are - APFS - ExFAT - ext4 - NTFS I'm using kernel version $ uname -r 4.18.0-193.6.3.el8_2.x86_64 I executed commands before and after my SSD. **BEFORE plug the USB External SSD** ls -alR /dev/ | grep -E "/dev/block:|sda|/by-|/dev/:" [joseluisbz@centos dev]$ ls -alR /dev/ | grep -E "/dev/block:|sda|/by-|/dev/:" /dev/: /dev/block: /dev/disk/by-id:
