Új FreeBSD bootloader

Címkék

Scott Long a FreeBSD Release Engineering Team egyik tagja írt egy bootloader front-end scriptet, amelynek segítségével a felhasználók engedélyezni/tiltani tudják az ACPI-t, single user módba tudják bootolni a gépet, stb. A motiváció az volt, hogy mostanában egyre több gond volt az ACPI-vel több gépen is, és ezzel a megoldással a felhasználók könnyen ki tudják kapcsolni boot időben az ACPI funkciót. Scott reméli, hogy a szkript már rajta lesz a FreeBSD 5.1 i386-os bootCD-n. Visszajelzéseket vár a fejlesztő a dologgal kapcsolatban.

Subject: New bootloader!

All,

I've written a nice little bootloader front-end script that allows one to enable/disable acpi, boot single users, etc. My primary motivation was to allow users to easily disable ACPI, since so many problems are popping up these days with it. Making the disabling of ACPI sticky is not that hard to do, probably a few lines of sh scripts in rcNG, but I haven't gotten to it yet. To use the new loader, grab it rom

and place it in /boot. Then copy frames.4th and screen.4th from /usr/share/examples/bootforth into /boot. Then edit /boot/loader.rc with the following diff. WARNING: if any mistakes are made and the script cannot start, it might leave your loader unable to load the kernel. In case of problems, either keep a fixit floppy handy, or recompile your kernel with embedded hints (so that things like the console will work) and load it from the boot1 loader.

I'm really hoping to have this be on at least the i386 bootcd for 5.1, so any feedback is appreciated.

Scott
