Sure thing. I'm just curious though, would you mind explaining what
"some conditions" since I don't believe I know? I can clone this bug so
the docs team is aware of the changes, but actually, even going through
them right now, it says /boot on LVM is not actually supported:
"Warning
Placing the /boot partition on an LVM volume is not supported." 
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Installation_Guide/sect-disk-partitioning-setup-s390.html#sect-create-lvm-s390

and here:
"For each new mount point you create manually, you can set its
partitioning scheme from the drop-down menu located in the left pane.
The available options are Standard Partition, BTRFS, LVM, and LVM Thin
Provisioning. Note that the /boot partition will always be located on a
standard partition, regardless on the value selected in this menu."
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Installation_Guide/sect-disk-partitioning-setup-s390.html#sect-partition-configuration-s390

So I'm not actually sure that docs needs to make any changes here.
