[Bug 983805] Re: Resume boot script fix makes /bin/resume unnecessary (kernel's internal swsusp)

[A Dasgupta]

Further Update:  Not a bug fix, but more code cleanup (the diff is
shorter) making the checking logic identical to that of the original
resumelib.c.

This post contains the diff, and the full script in the following post.
This version should be preferred over the one in post #4/#5.

Title:
  Resume boot script fix makes /bin/resume unnecessary (kernel's
  internal swsusp)

Status in “initramfs-tools” package in Ubuntu:
  New

Bug description:
  This patch to scripts/local-premount/resume makes the C program
  /bin/resume unnecessary (from klibc-utils, source resumelib.c).

  The source shows that C program /bin/resume is simply echoing
  major:minor[:offset] onto /sys/power/resume, which is exactly
  what is done in this patch, but using shell commands.

  This patch is against initramfs-tools_0.99ubuntu12, but
  the file scripts/local-premount/resume has stayed the
  same for quite a while (at least since maverick).

  I will also post the full script file.
