dmidecode executed for all commands but not in non-privileged path

[justindthomas]

Description

All commands executed as non-privileged generate an error related to dmidecode. This does not seem to affect the function of the device, but is an annoyance. I started working with a different manufacturer's device at work (a Ragile unit) and noticed that it does not have this peculiarity, so decided to raise an issue here for my Dell unit.

Steps to reproduce the issue:

Here is some example output (summarized) from my Dell N3248TE-ON:

jdt@sonic:~$ show system-health
failed to import plugin show.plugins.cisco-8000: [Errno 2] No such file or directory: 'dmidecode'
Usage: show system-health [OPTIONS] COMMAND [ARGS]...

  Show system-health information

. . .
jdt@sonic:~$ sudo show system-health
Usage: show system-health [OPTIONS] COMMAND [ARGS]...

  Show system-health information
. . .
jdt@sonic:~$ show platform
failed to import plugin show.plugins.cisco-8000: [Errno 2] No such file or directory: 'dmidecode'
Usage: show platform [OPTIONS] COMMAND [ARGS]...

  Show platform-specific hardware info

. . .
jdt@sonic:~$ sudo show platform
Usage: show platform [OPTIONS] COMMAND [ARGS]...

  Show platform-specific hardware info

. . .
jdt@sonic:~$

Describe the results you received:

The expected output, but with a warning about a missing dmidecode command.

Describe the results you expected:

No warning about the dmidecode command (which does exist, but is only in the path for the root user).

Hi,

This happened to me as well (https://github.com/sonic-net/SONiC/issues/1494)

It seems to only affect the Dell N3248 for some reason. I have not had this issue on Celestica or Edgecore switches
