I am running Fedora22 Workstation. The current partitioning scheme is /boot and an encrypted LVM containing /, swap and /home.

I am installing Fedora22 KDE Spin on some free space on the same disk. swap and /home will be shared between the two installations. Is it possible to also share /boot?

Instead why don't you just install KDE desktop environment alone to your existing Fedora 22? You will run into lot of issues if you go by your plan!

Issues like kernel overwrite, low space in /boot and senseless package duplication. The problems you may have if you install the environment is configuring the display manager and session bugs. Much easier to fix than the former problems. For instance, KDM to GDM issue.

@anishjp and @NuuN I am aware of the difficulties/ duplication, etc. But I wanted to try a different file system for the OS element (btrfs) to see if it makes any difference in performance.

Presently, I have a separate /boot partition and I am yet to see any sizeable difference in speed

Based on the replies I got, I chose not to share /boot partition.

My current partitioning scheme is: /boot for OS1, an encrypted LVM partition containing /, /home and swap. This is a ext4 partition. Of these, /home and swap are shared with OS2.

OS2 has its own /boot and its own / that is on btrfs.

You could also use LVM as the block device for BtrFS. Would then avoid using LVM management tools on BtrFS volumes.
