    For some reason I found it difficult and confusing to write out the procedure for this before starting. (Yes, I make a written procedure for every session.) Google AI Mode got involved.

    Section 2.5, creating a file system on the partition. According to Google AI Mode, I don’t need to create a file system on the LFS partition, because GParted is a partition editor and has already made the file system using the same tools (mkfs) that someone would use doing it manually.

Be sure to install those if your distribution provides them.” I googled and then checked with AI Mode each of the essential programs, looking for software headers, -dev, and -devel.
