Hi, > It would be nice if you could tell us belief usage of the patch. OK, sure. It's against bazaar repository, so you have to build it from repository source instead of latest stable release tarball. To build with stable release(1.97.2), you need to modify fs/nilfs2.c not to use grub_xasprintf, but use grub_malloc and grub_sprintf. You may get reject for makefile, but I think it'll be OK. Here are the instruction to retrieve grub repository and build the softoware. $ bzr branch http://bzr.savannah.gnu.org/r/grub/trunk/grub $ cd grub $ patch -p0 < /path/to/the/patch $ sh autogen.sh $ ./configure $ make you need "make install" as usual. It will install under /usr/local without giving any parameters for ./configure. The "make install" won't install grub to MBR. To install grub into MBR, you have to "grub-install" to target disk. For example, assume that you have nilfs2 filesystem on hdb1, mounted on /mnt and want to enable hdb as bootable. You'll do # grub-install --root-directory=/mnt /dev/hdb This will install grub into hdb's MBR and other required files into following 32KiB blocks. Fuhtermore, it'll install files under /mnt/boot/grub. Those files are not required to boot grub to read the filesystem. hdb is now self bootable disk. You'll just connect it as hdb and grub will boot up. Note, during grub-install, /boog/grub/grub.cfg will be copied int to /mnt/boo/grub, which is not the one for hdb. So you have edit menu at first time you boot with hdb. After boot the system, you can reproduce the menu by grub-mkcofnig > /boot/grub/grub.cfg Enjoy! regards, -- Jiro SEKIBA <jir@xxxxxxxxx> -- To unsubscribe from this list: send the line "unsubscribe linux-nilfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
