I am fine with shipping GRUB up to some commit in Slint, but not all
distributions accept to do that, or to carry a zillion patches as does
Debian.
As result, end users complain "GRUB is broken" whereas a patch that fix the
issue of which they suffer of has been committed upstream a long time ago.
An example that comes to mind is:
6643507ce30f775008e093580f0c9499dfb2c485
Folks running Slackware-current also suffer of it:
