For example: cross-build? self-hosted only? system version starting from on the machine doing the build? gcc 4.2.1 based starting point? single boot media vs. able to have an old context produce separate/new boot media? the amount of RAM and swap/page space? (You may be able to come up with more things to identify that might contribute to how to progress.) I'm working towards updating, but I'll likely be cross building and producing new media from a bootable backup of the old media. (Helps avoid potential live-update issues.) So what I end up doing may well not match what you would do. =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
