Pkg xen devel - Aug 2021 - [PATCH 0/4] More ideas on Debian packaging of Xen

Sorting is a maintainance task which is helpful for easier reading.

.gitignore files don't actually behave in an intuitive way.  *All* lines
are wildcards, unless care is taken patterns can catch files in
subdirectories.  Ensuring all names start with a slash ensures they
exclude filenames in subdirectories.

Several entries are expected to be directories, not ordinary files.
Ensure these get reported if a file replaces the directory (suffix
slashes).

Hopefully the settings with patch formatting are more to the maintainer's
taste (I prefer the other way).  Two of these had already been suggested,
but I'm sending them again since they still seem to have value.

This batch are mostly independent and can readily be reordered.  The
first and last interact some, but reordering them should be
straightforward if you desire to do so.

I still like the idea of creating the "xen-domu-bootloader" virtual
package for PvGRUB to fill.  Perhaps this should be "xen-domu-loader"
or
maybe there should also be "xen-domu-bootloader-X.Y".


I've gotten interesting results during my experiments with Xen on ARM
hardware.  PyGRUB is pretty well version-independent.  PyGRUB from
Xen 4.11 worked perfectly for loading kernel/initial ramdisk on a
Xen 4.14 hypervisor.  This suggests PyGRUB should be a package separate
from the Xen utils.  This would also allow completely removing PyGRUB
from a system.

The currently visible alternative is wishlist bug #978595.  On arm64
the resultant XEN_EFI.fd is pretty well ideal.  It has higher overhead
than PvGRUB, but it can load things besides Linux.  Presently it is the
only loader known to function for the WIP FreeBSD port.

The packaging job is incomplete.  I make no claims of being a full Debian
developer, simply someone with some interest who wants things to work.
Notably I suspect this would result in an incorrect 4.11 => 4.14 upgrade.
During the 4.11 => 4.14 upgrade, the xen-pygrub package should be
installed if xen-utils-4.11 was installed.  I suspect both xen-utils-4.14
and xen-pygrub need to be marked as replacing xen-utils-4.11 (possibly
xen-utils-4.4 and xen-utils-4.8 too).

Now to learn a bit about xenstored and stubdomains...
