My own trend would be to
Because the minimal live uses a squashfs, which is mounted and union-ed before init is called, AFAIK. The disk controllers are not necessary (and in fact I have stripped them off from the microscopic version of the initramfs), but might be useful if you want to use the live image as a rescue cd, and boot into an existing / on your drive. Not necessary. Maybe useful. > rebuild the kernel with those drivers statically linked and boot > directly to the cdrom without and initramfs. > Oh, sure we could. But my point is to use standard packages from the Devuan repo, without too much of customising/recompiling. Otherwise we could also recompile everything with uclibc, as done in other minimal distro, and have a truly microscopic userland, but that would be *another* distribution, not a Devuan ;) Thanks KatolaZ -- [ Enzo Nicosia aka KatolaZ --- GLUG Catania -- Freaknet Medialab ] [ me [at] katolaz.homeunix.net -- http://katolaz.homeunix.net -- ] [ GNU/Linux User:#325780/ICQ UIN: #258332181/GPG key ID 0B5F062F ] [ Fingerprint: 8E59 D6AA 445E FDB4 A153 3D5A 5F20 B3AE 0B5F 062F ] _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
