gnome boxes image folder should be marked nodatacow?

[Richard Shaw]

Before I submit a BZ I figured maybe some discussion was in order.

As the default fs is now btrfs and it's well known to be bad for VMs, I'm
surprised this wasn't already implemented.

Since the folder is created on the fly in the user's home directory this
can't be easily fixed through packaging. In fact the only way I can think
of is to create a bash script wrapper for the gnome-boxes executable and
check for the directory, create it if needed and chattr +C the directory.

Is there a better solution?

Thanks,
Richard
