grub vs. lilo 1

[Nostradamus]

Never worked with GRUB before. But I'm installing Red Hat 7.2 and noticed that grub was an option.

how does GRUB work.
what is the difference between grub and lilo?

Any ideas regarding the Software raid in Red Hat 7.2 would also be appreciated...

thanks in advance... /Sören

Hi,

Grub stands for Grand Unified Boot Loader and is functionally similar to lilo. The home page is here -->

http://www.gnu.org/software/grub/

and the manual here -->

http://www.gnu.org/manual/grub-0.90/html_mono/grub.html

.

I haven't used it myself but one of the advantages is supposed to be that, once installed, you don't have to update the binary boot record if you change the config file. With lilo, if you change /etc/lilo.conf it does nothing to the boot process. You have to run /sbin/lilo which reads that conf file and creates an updated binary boot record. By contrast, it appears that you can make changes in the grub config file (/boot/grub/grub.conf) which will be read at boot time. So you'd just edit that file and reboot.

Regards

can't believe why they haven't fixed the "/sbin/lilo problem" yet.
I have this disease, kind of. Whenever I vi that darn lilo.conf I completely forget everything resembelling li+lo. Have been stuck during bootup one to many times. Perhaps I should go with grub just because of that feature.

Thanks for the links Ifincham. Guess I should have tried the gnu.org before asking but what the... /Sören
