System Installation and Boot Loader Management
1: Why is it good practice to check the md5sum of an installation CD or DVD image (in .iso format or similar) before writing it to media such as a DVD or CD?
Answer:
Doing an md5sum of an iso image will reduce the chances of a failed installation. A bad installation image may lead to errors on the system or cause the installation to fail.
2: The /boot/grub/grub.conf file contains a line consisting of "timeout=10", what are the consequences of changing it to "timeout=20"?
Answer:
When the computer starts up it will count down 20 seconds and then boot the selected/default grub entry.
3: A system has multiple grub entries in the /boot/grub/grub.conf configuration file. How would you edit this file in order to remember the operating system selected and save it as the default for the next boot?
Answer:
The “savedefault” and “default saved” commands may be used to store the selection as seen in the following extract from the /boot/grub/grub.conf file:
default saved
timeout=10
title Fedora (2.6.38.6-26.rc1.fc15.i686.PAE)
kernel /boot/vmlinuz-2.6.38.6-26.rc1.fc15.i686.PAE ro
initrd /boot/initramfs-2.6.38.6-26.rc1.fc15.i686.PAE.img
savedefault
