30-31: Ensure consistent yum flag placement and tighten script invocation
The current command is:

curl -1sLf 'https://dl.redpanda.com/nzc4ZYQK3WRGd9sy/redpanda/cfg/setup/bash.rpm.sh' | \
sudo -E bash && sudo yum install redpanda -y

Recommendations:

• Move the -y flag directly after install for consistency and readability:

  - sudo yum install redpanda -y
  + sudo yum install -y redpanda

• Consider dropping -E on the sudo bash invocation to avoid unintentionally preserving user environment variables in a FIPS-sensitive context.

34-34: Alternative install note is clear and correct
The note:

NOTE: Alternatively, you could run `sudo yum install -y redpanda-fips`, which also picks up and includes the `redpanda` install package.

is accurate and follows the non-interactive install pattern. No changes required.

Walkthrough

The installation instructions for Redpanda on RHEL-based Linux systems were updated. The previous use of apt commands was replaced with steps appropriate for RPM-based distributions, specifically using a setup script and the yum package manager. The documentation now clearly distinguishes between installation steps for RHEL-based and Debian/Ubuntu systems. Notes were updated to reference the correct package manager for each system type. No changes were made to the Debian/Ubuntu instructions or to any exported or public code entities.

Poem

In the land of Linux, a change takes root,
RHEL now gets a yum-filled reboot.
No more apt for Redpanda’s quest,
A curl and a script now handle the rest.
Debian stays steady, instructions unchanged,
While RPMs and yum are neatly arranged.

• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.

34-34: Nitpick: streamline the note for conciseness
Consider rephrasing to remove unnecessary words and clarify that redpanda is installed as a dependency:

- NOTE: Alternatively, you could run `sudo yum install -y redpanda-fips`, which also picks up and includes the `redpanda` install package.
+ NOTE: Alternatively, run `sudo yum install -y redpanda-fips`, which also installs the `redpanda` package as a dependency.

30-31: Correct use of RHEL installation command
The updated instructions now properly use the Redpanda RPM setup script followed by yum install to enable FIPS mode on RHEL systems. This aligns with RHEL’s package management.
