I have walked all over Paul Richards code again, and severely lobotomized some of his stuff, in order to cut some corners for the 2.0-Alpha release. I belive that we can now manipulate fdisk and disklabel-stuff sufficiently for the release to actually be produced. It's not that I don't like Paul and his code, I just need something I can kick out of the door RSN. Sysinstall is now under absolute code-freeze, only Jordan has my permission to commit to this code (stage0 & 5). I would appreciate if everybody else would finds problems in sysinstall send patches to me, and I will commit them. THANKYOU. The fdisk/disklabel editors are made in pure ncurses, and follow a model "a`la spreadsheet". There are some important functions which are missing still, and I would appreciate if somebody would look at them. The FDISK part needs a "whole-disk" option, and it needs a "rewrite MBR-boot code" option. The DISKLABEL part needs to be able to "import DOS-partition". Both need a "HELP" function, (display a file "/HELP" using dialog is OK). It seems to me like the wd.c and sd.c should reread the physical record when a DIOCGDINFO is made, so that they can pick up changes in the MBR-data. Otherwise there will be a couple of weird cases where we cannot avoid replicating code from the kernel. If you want to play with this, look at src/release/Makefile. You may need to step back to version 1.38 of sys/i386/isa/fd.c to make "rootable" floppies, it is not clear at this time if that indeed is the problem I have been having. Sleep well, my friends, and expect the real Alpha in 24H, if the tree is still solid.
