Pkg xen devel - Jan 2019 - Bug#919758: xen-hypervisor-4.8-amd64: Wrong examples provided in GRUB config file

Package: src:xen
Version: 4.8.5+shim4.10.2+xsa282-1+deb9u11
Severity: minor

Dear Maintainer,

the GRUB configuration file /etc/defaults/grub.d/xen.cfg contains incorrect
examples:

1. Bad syntax for dom0 memory allocation settings:

   https://xenbits.xen.org/docs/unstable/misc/xen-command-line.html#list

   Bad syntax (max value is ignored this way):
dom0_mem=<size>[M]:max=<size>[M]
   Correct syntax: dom0_mem=<size>[M],max:<size>[M]

2. Bad syntax for earlyprintk usage:

  
https://github.com/torvalds/linux/blob/master/Documentation/admin-guide/kernel-parameters.txt

   Bad syntax: earlyprintk=xenboot
   Correct syntax: earlyprintk=xen

Please correct the examples to avoid confusion for users new to Xen (like
myself).

Thanks,
Gergely

Thanks for the report. You are completely right.

I took some time today to update the examples in this file a bit.

Here's the result:
