Draft Notes:

• Travis CI uses LXD containers, which prevents the used of the --privileged flag. Re: http://db2indocker.blogspot.com/2015/04/db2-do-not-start-in-un-privileged.html, but it doesn't seem relevant as all current Ubuntu versions use Kernel v4+
• In the ppcle64 arch, there seems to be a problem with one of the layers:

  failed to register layer: Error processing tar file(exit status 1): lchown /tmp/LicenseAgreement.pdf: invalid argument
  
  Unable to find image 'ibmcom/db2:latest' locally
  

• In GitHub Actions, the DB2 service never seems to start. Do we need establish a connection with the db2 CLI first? (Probably not.)
