NO-ISSUE: images/tools/Dockerfile: Install iotop, if that fails fall back to iotop-c

[sdodson]

… iotop-c

Summary by CodeRabbit

• Chores
  • Docker image build updated to ensure the iotop monitoring tool is reliably included during image creation.
  • Installation logic simplified for more predictable and maintainable image builds, reducing conditional checks and variability.

Walkthrough

Replaces conditional iotop detection and variable assignment with a static inclusion of /usr/sbin/iotop in the Dockerfile package list and removes the yum list iotop check and IOTOP_PKG variable.

Changes

Cohort / File(s)	Summary
Docker Build Configuration images/tools/Dockerfile	Removed conditional yum list iotop check and IOTOP_PKG variable; added explicit /usr/sbin/iotop entry into INSTALL_PKGS, simplifying package selection logic and eliminating dynamic fallback handling.

Check name	Status	Explanation	Resolution
Title check	⚠️ Warning	The PR title does not match the actual implementation in the changeset. The title promises a fallback mechanism (install iotop, if that fails fall back to iotop-c), but the changes only install the static path /usr/sbin/iotop without any fallback logic.	Update the PR title to accurately reflect the changeset, such as 'images/tools/Dockerfile: Replace conditional iotop installation with static path' or implement the fallback logic described in the title.

Stable And Deterministic Test Names	✅ Passed	Pull request only modifies Dockerfile; no test code with dynamic test titles is introduced.
Test Structure And Quality	✅ Passed	The PR modifies only images/tools/Dockerfile, a Docker build configuration file with no test code changes, making this test quality check not applicable.

The way we've dealt with problems like this in the past where binaries shift from one package to another is to just name the path to the binary in the installspec.

i.e. something like /usr/bin/iotop and then the resolver will find the package that provides it.

please test this suggestion, it's just a suggestion.

10-51: ⚠️ Potential issue | 🟠 Major

Avoid reusing install specs as rpm -V verify targets.

/usr/sbin/iotop is a valid installspec for yum, but rpm -V treats arguments as package names by default, not file paths. Passing /usr/sbin/iotop to rpm -V ... $INSTALL_PKGS will fail verification because /usr/sbin/iotop is not a valid package name. Split install specs from verify targets, and resolve the iotop owner package before rpm -V.
