[PATCH initramfs-tools 0/9] Fix resume device configuration

Show all headers | View raw

[Multipart message — attachments visible in raw view] - view raw

The change in version 0.128 to wait for the resume device to appear
uncovered a number of systems for which the resume device is not
properly configured.  In fact, systems with swap partitions that
are never available at boot could not be configured correctly,
other than by adding 'noresume' to the kernel command line!

While working on that, I found and fixed a couple of other
longstanding bugs in resume device selection.

This patch series:

- Fixes the sorting of swap partitions
- Makes the RESUME variable work like every other configuration
  variable, and documents it
- Adds support for RESUME=none (disable resume) and RESUME=auto
  (explicitly request automatic selection)
- Adds warning and informational messages where the resume device
  configuration is automatically fixed-up

I'm stil not entirely happy with the automatic resume device
selection.  I would prefer to read the kernel's selection from
/sys/power/resume, but I found experimentally that this isn't set on a
fresh boot under older kernel versions.  Secondly I would like to
automatically filter out device types that we know won't be
available at boot (e.g. zram).  But I think this may have to do.

If no-one finds issues with this these changes then I'm hoping
to make one more release for "stretch" with just these.

Ben.

  hooks/resume: Use correct sort options to select the biggest swap
    partition
  initramfs.conf(5): Clean up split between general and NFS variables
  Support setting of RESUME in initramfs.conf or anywhere in conf.d/
  initramfs.conf(5): Document the RESUME variable
  hooks/resume: Check for chroot earlier
  Allow disabling resume from disk at build time by setting RESUME=none
  Support requesting automatic selection of resume device with
    RESUME=auto
  hooks/resume: Report when we might be doing something surprising
  NEWS: Add entry explaining the need for RESUME=none on some systems
