Have fixed size boot partition by default, make it user-overridable
Right now we are guessing what would be the smallest possible size for the boot partition. Every now and then, this causes issues, because it is too small (as the guessing failed for example, it's not trivial to get the size right because the host running pmbootstrap may have a different file system etc.) and then users need to reflash.
Let's set the default boot partition size to 100 MB and allow users to override it as argument to pmbootstrap install
. If we end up having a device, that really needs a very small boot partition, we could also add a deviceinfo option in the future. In my experience, it does not really matter with most devices.
