Thank you for the tweak, Greg. That's a biggie because along the way, we've seen how things change and fail for that very reason. One of my partitions' terminal root now calls itself by a package name. NO CLUE how it happened because I wasn't root while the associated package was being extracted. Confirming placement of quotation marks, if used, would be one checkpoint for a massive fail like that. There's also that thing about how terminals will interpret the different types of quotes (dumb/typewriter/ASCII versus typographic/curly/smart) very literally. I experienced THAT fail firsthand and now try to remember to plug anything I copy into a plain text editor before then recopying over to a terminal. Am wondering if, am more like hoping that this quotation marks part of it would have stood out when I research how to further customize my own setup. This will be a priceless personalization if I can eventually coerce it to say "(debootstrap) chroot" in place of some of the characters there. Shh, don't tell me how.
