Add bcc tools to PATH

[rustyrazorblade]

When using sudo we have to supply the full path to the tools, like this:

sudo /usr/share/bcc/tools/xfsslower 0 -p $(cassandra-pid) | awk '$4 == "R" { print $0 }'

Add /usr/share/bcc/tools/ to the system PATH.

Proposal: add-bcc-tools-to-path

• Gather context: find where PATH is configured in the codebase
• Create openspec change at openspec/changes/add-bcc-tools-to-path/
• Generate proposal.md
• Generate design.md
• Generate tasks.md
• Commit and push

Change: openspec/changes/add-bcc-tools-to-path/

Root cause: Two separate PATH sources exist on database nodes:

• /etc/profile.d/aliases.sh (login shells) — already includes /usr/share/bcc/tools
• /etc/environment (sudo sessions, via PAM) — does not include /usr/share/bcc/tools

When you run sudo xfsslower ..., sudo uses the PATH from /etc/environment, so the tool can't be found without a full path.

Fix: Add /usr/share/bcc/tools to packer/cassandra/environment (which is installed to /etc/environment). This is a one-line change.

Tasks:

1. Add /usr/share/bcc/tools to PATH in packer/cassandra/environment
2. Run packer tests to verify

Ready for implementation — run /opsx:apply to start.

Applied: add-bcc-tools-to-path

• Read OpenSpec tasks (inferred from approved proposal on previous branch)
• Add /usr/share/bcc/tools to PATH in packer/cassandra/environment
• Commit and push

Change made: Added /usr/share/bcc/tools to the end of the PATH in packer/cassandra/environment (installed to /etc/environment on db nodes). This allows bcc tools like xfsslower to be invoked via sudo without specifying the full path.

Note: Packer tests require Docker/AWS and can't be run in this environment — please verify locally with ./gradlew testPackerCassandra before merging.
