Exercise 23.1: Logical Volumes

Working through the above exercise, I encountered the response shown below; obviously this has worked so does it mean 8e is an OS implementation-dependent option (I'm using CentOS 8)?
Command (m for help): t
Partition number (1,2, default 2):
Partition type (type L to list all types): 8e
Type of partition 2 is unchanged: Linux filesystem.
Also, if you do a list, there's no 8e:
...

Thank you for brining this up, can you please post "disk -l /dev/(disk). Mine shows:
[[email protected] ~]# fdisk -l /dev/sdc
Disk /dev/sdc: 931.5 GiB, 1000204886016 bytes, 1953525168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x2376fd81Device Boot Start End Sectors Size Id Type
/dev/sdc1 2048 1953523119 1953521072 931.5G 7 HPFS/NTFS/exFAT
[[email protected] ~]#_I suspect your Disklabel type is GPT.

On GPT partition tables LinuxLVM is type 31.
Thank you for the input,The LinuxFoundation provided Virtual Machines do not currently use GPT for partitioning.

Thank you Lee; you are correct -- here's my listing:
Disk /dev/sda: 931.5 GiB, 1000204886016 bytes, 1953525168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: gpt
Disk identifier: 863796EB-8E28-4E72-8BA1-0390AB3CBAB3Device Start End Sectors Size Type
/dev/sda1 2048 390627327 390625280 186.3G Linux filesystemErnest

on my system the "L" type subcommand clearly shows 8e as Linux LVM. Please note that in my experience I have never seen any utiltity on the system care what type you put in with fdisk. I have often forgotten to change it from the default when doing something else and the mount command does not care as it examines the beginning of the partition before doing anything with it . As far as I can see, the "type" is a historic relic of not much importance except in printouts
