Niltze Ed- Regarding reiser4, software framework release number (SFRN) 5.1.3, version of reiser4progs-2.0.0 utilities, is mkfs.reiser4 -yo "create=reg40" still appropriate to formatting a rootfs (/) media and/or a partition prior to installation of a GNU/Linux distribution, i.e., Debian Buster for AMD64? I have already built/embedded the SFRN5 kernel into preliminary metztli-reiser4-sfrn5.iso, minimal netboot installation media < https://metztli.it/buster-reiser5/metztli-reiser4-sfrn5.iso > < https://metztli.it/buster-reiser5/metztli-reiser4-sfrn5.iso.SHA256SUM > and, using the formatting command above, installed onto ~2TB and ~200GB VirtualBox instances with Reiser5 rootfs, i.e., < https://metztli.systems/system/media_attachments/files/000/000/161/original/ca7acd7030d7565b.png?1583319334 > < https://metztli.systems/system/media_attachments/files/000/000/162/original/e3e043e640d5ee97.png?1583319358 > as well as into a ~100GB physical partition with Reise5 rootfs. But I wanted to ascertain the default format command for the hacked SFRN5 Debian installer (d-i) for Buster (stable) distribution prior to making the image public.
