I tried using /boot on btrfs a couple of times some days ago, and it kept failing each time until I used ext4.

This is bad UX. If I need to "fiddle with enough" on a problem that wasn't supposed to be a problem, it should be addressed.

By default, when using the automatic install process, /boot uses ext4 when it should be using btrfs instead, and when using the custom partitioning tool, it should allow me to use btrfs without it being a reason to failure.

Hi,

`/boot` can be used on btrfs. However, Anaconda forces me to use ext4 in that specific, when it shouldn't if you use btrfs.

I'd like to request allowing `/boot` to be used on btrfs.

You can do this in Custom partitioning, if you fiddle with it enough.
However... I recommend you create a 1-2G Btrfs boot outside of the
installer. The installer will let you assign it to the /boot mount
point without reformatting it.

The reason is it's better to use the 'mkfs.btrfs --mixed' option for
file systems of this size.
