Description Yaniv Lavi 2018-01-10 12:51:56 UTC

Description of problem:
Scan alignment is a feature that is only relevant to OSes that are no longer supported.
Therefore we no longer want to support it and remove it.

Comment 1 Nir Soffer 2018-02-19 14:23:55 UTC

Richard, can you confirm that scan alignment is not needed any more?

Comment 2 Allon Mureinik 2018-02-19 14:30:54 UTC

Let's wait for Richard to weigh in here, but according to [1] this relates to "Operating systems older than Windows 2008 and Linux before ca.2010".

Comment 3 Richard W.M. Jones 2018-02-19 14:41:07 UTC

Right, exactly as Allon says.  I don't know if you're supporting
those still.

Comment 4 Allon Mureinik 2018-02-21 07:41:19 UTC

Derek, we are going to remove the Scan Alignment feature in the upcoming 4.3 release.
I went over the current (4.2 beta) administration guide and could not find any reference to it, but asking just to on the safe side - is there anything we need to do preemptively in 4.2 from a documentation standpoint before removing this feature in 4.3? Do we need a separate BZ for it?

Comment 6 Derek 2018-08-14 17:41:02 UTC

Allon, it was deprecated in 4.2 and will be removed in 4.3?  Is that correct?

Comment 7 Nir Soffer 2018-08-14 18:25:03 UTC
