Should probably also ask JSV and RRHB. (If they're on this list, they're primarily in lurk mode. I know they both have full plates.) The book describes the popular recipe of that time in excruciating detail. Coulda, woulda, shoulda been simpler. (But I do not fault those whose names are on the Redbook for the complexity. It's almost impossible to draw in such a wide and varied audience and accommodate all of their reqs.) I'll cobble-up a blog post with the details rather than clutter mailboxes. > I look back and now reflect - are Containers and Docker the new "read-only > root"?

Read-only ROOT turned out to be unpopular (at Nationwide). Read-only SYSTEM would have been better, and can be demonstrated to work well. But there's so little tolerance for anything foreign in mainstream system/package/container management that few bother. I know one group in Ohio that got serious about shared root (not R/O in their case, so they used NFS for it). > IBM Sales Rep > Hello! My name is Taylor. Welcome to IBM Live Chat – Sales.

Doesn't *sound* like a synth. But you were chatting with the company which owns Watson.
