Are newer options such as UUID's supposed to make life easier or harder?

Moving to cloudlinux 9 from cloudlinux 6 and reading https://docs.cloudlinux.com/cloudlin...-compatibility, I noticed:

Replacing the server hardware affects specifications and support for such hardware from CloudLinux OS end. It is most likely that the CloudLinux OS will stop working if you replace any hardware component on the server.

Example: the same HDD/SSD/NVMe model will have a new UUID and CloudLinux OS is mapped to old UUID which break the boot procedure.

Are newer concepts such as UUIDs instead of just /dev/sda /dev/sda1/ /dev/sda2/ etc. making life easier, or more difficult? The above sounds like a huge disadvantage (not being able to replace a hard drive or any hardware if a component should need replacing or upgrading.)

Hi,

The challenges associated with hardware replacement and UUID changes are not unique to CloudLinux, they apply to most modern Linux distributions that utilize UUIDs for device identification. However, the disks UUID is just an example here and can be easily solved switching back to /dev/XYZ from within fstab or even switching the UUID with tune2fs.


There are few advantages of Using UUIDs you would need to know:

Consistency: UUIDs remain constant regardless of the order in which devices are detected by the system. This means that even if you change the hardware configuration, the UUIDs will still point to the correct partitions.

Avoiding Conflicts: When using traditional device names, the system may assign different names based on the boot order or hardware changes, which can lead to confusion and boot failures. UUIDs eliminate this issue.
