Reviewing the patch from bug 554009, I have the following comments:
- as the patch sets SWAPTYPE, no need to set it in line 24 of the
original script immediately before the patch: just run wait-for-root (if
that is actually needed);
- the test for $resume_offset would be safer if it looked for a number, eg:
[ "${resume_offset}" -ge 0] 2>/dev/null
- lines 63-67 of the original script can be replaced by line 64 only: no
need for a separate resume_offset case.
I confirm that the patch enables hibernation and hybrid-sleep to a
/swapfile using uswsusp with LXLE 16.04 identifying as "4.4.0-96-generic
#119-Ubuntu SMP Tue Sep 12 14:58:51 UTC 2017 i686 i686 i686 GNU/Linux",
and also with the above changes.
Why is no-one picking this up? Still 3.5 years of support for Ubuntu
16.04 LTS.
