Help to choose partition root

I am Root partition in Ext4 format and Luks mode
I wanted to know to format BTRFS better because I see new that all installed on BTRFS

See the section How-To Convert an ext2/3/4 filesystem in a BTRFS system in [HowTo] Btrfs and Snapper

My boot partition is in the root. Is it better to be separately in the correct format ext4

I have no idea - I use only ext4.

Btrfs have features ext4 doesn’t, though depending on your use case, they may not be needed.

AFAIK the file system of the root partition has negligible incidence.

Thanks for the reply
I decided to convert ext4 to btrfs

Will the next mount be converted to btrfs with this command?

mount /dev/sdXN /mnt
btrfs subvolume list /mnt

I didn’t realize that did you create or convert partitions?

For me all in an Ext4 partition luks (boot/home,…)
Do I need to make a separate Home and such a separate partition for boot

Also,I am not familiar with mount options at all, please someone write the mount option for root and swap file.
Meanwhile, I don’t want to use snapshot

He created a backup like copying his important data to another partition or hard drive, then removed old Ext4 partitions and created new Btrfs partitions, then copied the data back.

I recommend you create a new VM with snapshot capability and learn how to setup and test Btrfs.
