#206937 — Has anybody run into problems setting noatime for the executable files on a Wheezy system (or any newer system)?

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

I'd like to set noatime (instead of relatime) for all of the partitions on my 
SSD, which basically includes all the executables (except for a few I've 
written myself and keep in a separate top level directory on my HDD).  

I've seen a statement some where that one needs to be careful about setting 
noatime for executables because -- well I don't remember the reason well 
enough to repeat it correctly here, something to do with some executables 
checking the atime (I guess) on their files (or files they use).

If anybody is still running Wheezy and has tried setting noatime for most of 
the exectables, did you run into any problems?

How about anybody running Jessie or anything newer?

It is my understanding that the warning pertains to data files of 
programs that look at atime -- mutt(1) is the often-cited example.  STFW 
some people also warn about tmpwatch(8) and (unnamed) backup programs:

I'm running Debian/Devuan on SSD since June 2018 with all partitions
flagged 'noatime' but /boot (ext2).  No problems so far that I have
noticed.
