How about this ?  Adjust to taste, correcting any
lies/misunderstandings, maybe adding references, etc.


Steps to reproduce:

  Follow instructions in xen-create-image, including suggestion to
  re-use host's initrd, to make a guest running stretch.  Try to boot
  it.

Expected behaviour:

  Guest boots promptly.

Observed behaviour:

  Guest pauses for a long time during boot waiting for the "resume
  device" to become available.

Analysis:

  This is because the initrd has the host's swap device configured.

  With stretch, and systemd, the delay is longer; earler Debian
  releases had a similar issue but the shorter timeout meant it was a
  less serious problem.

Suggested remedy:

  It is unfortunate that the initrd has the resume device baked into
  it.  Normally this kind of thing (eg root=) comes via the command
  line.  So maybe the bug is in the initrd generation.

  Alternatively, maybe xen-create-image should write a setting "extra"
  into the domain config file "resume=<swap device>".


Ian.
