Fwd: [openwrt/packages] coreutils-who: not returning any useful output (Issue #21548)

[Peter Smode]

   (resending because I got some odd message from your mail server
   indicating this may not have gotten through due to a dkim issue)

   I was referred to you in this thread from the OpenWRT project. The who
   utility is not returning any useful information. Follow up by Georgi
   Valkov is in the email below, as is the link the the thread on GitHub.
   Georgi confirmed the fault is present in several versions, going back
   to 8.32-6. My original report follows:

   Environment: (x86, 64, OpenWrt v 22.03.05)

   Description:
   coreutils-who v9.0-2 appears to be non-functional in my environment.
   Executing the command who by itself or with "-a" returns no output at
   all. Adding -H or -Hl will return the column headings, but no data
   beyond that. -q returns a blank line, then "# users=0"

   I reproduced the behaviour you described on the following versions of
   coreutils-who: 9.3-1 9.2-1 9.1-1 9.0-2 9.0-1 8.32-6. I am not able to
   go back in time before version 8.32-6 using simple git revert.
   Platforms tested: x64 and WRT3200ACM. OpenWrt SNAPSHOT
   r22888-86adc89390.

   coreutils-who-9.3 on macOS Ventura 13.4.1 (c) (22F770820d) works fine,
   except for -Hl which prints only the title row.
   coreutils-who-8.32 on Ubuntu 22.04.2 LTS kernel 5.15.0-76 works fine.

   Did any previous version of coreutils-who work in the past on OpenWRT?
