I'm confused....

Hello,

I'm little confused with the LINUX system. There are several things that I don't understand.

What's the difference between grub.conf in /etc and that in /boot/grub?? why are there more than one grub configuration file?? Should I edit both to edit my grub?

The same with network configuration, there are three similar files:
1- /etc/sysconfig/network-scripts/ifcfg-eth0
2-/etc/sysconfig/networking/profiles/default/ifcfg-eth0
3-and two resolv.conf files for DNS : /etc/resolv.conf and /etc/sysconfig/networking/profiles/default/resolv.conf


And about the “mounting” issue, I CAN open and edit my files in the NTFS partitions and flash disks and CD/DVDs WITHOUT mounting them.......you'll say that FEDORA11 auto mounts them, ok............then why is the /mnt folder empty???!!!!!!!


Firewall: Why when I disable the iptables service and then open
system-->administration-->firewall ..... I find it NOT disabled???

Kernel: I understand that when a new kernel is installed, the old one shouldn't be removed to avoid a complete unrecoverable crash of the system.........What if I want to remove the old kernel, am I supposed to delete every single file that points to the old kernel??

Why does enabling the desktop effects require a package called compiz??? If it's so nessecary why isn't it included in the installation DVD??


YES, I'm confused and can't find a logical answer to those questions....

NOTE: I'm a Fedora 11 user with GNOME environment..

I hope that you have some answers here.....

Thanks,

Because not all distributions use the /mnt/ directory the same way, if at all. Some distributions mount things in the /media/ directory instead.

I've never had any issues leaving an older version of the kernel on a system. I've had some instances (particularly when beta-testing a new release) where I had five an six previous kernel versions and none of them caused any problems.

Why does enabling the desktop effects require a package called compiz??? If it's so nessecary why isn't it included in the installation DVD??

Short answer: desktop effects is compiz. Compiz provides the effects. You can't have them without that program. It's like asking "why does opening a web browser require a package called Firefox"?

As for why it's not included, that's anyone's guess. One reason might be because desktop effects require third-party, closed-source 3D drivers for most people's hardware and those can't be included on the DVD due to licensing issues.

Some of the files you mentioned are just links to the other files. These were probably created due to legacy apps expecting to find certain files in certain locations.
