Installation code 17 Modifying /etc/fstab for your machine

Your Gentoo Linux system is almost ready for use. All we need to do now is configure a few important system files and install the boot loader. The first file we need to configure is /etc/fstab. Remember that you should use the notail option for your boot partition if you chose to create a ReiserFS filesystem on it. Remember to specify ext2, ext3 or reiserfs filesystem types as appropriate.

Use something like the /etc/fstab listed below, but of course be sure to replace "BOOT", "ROOT" and "SWAP" with the actual block devices you are using (such as hda1, etc.)

Code listing 17.1: Editing fstab

# /etc/fstab: static file system information.
#
# noatime turns off atimes for increased performance (atimes normally aren't
# needed; notail increases performance of ReiserFS (at the expense of storage
# efficiency). It is safe to drop the noatime options if you want and to
# switch between notail and tail freely.

# <fs> <mount point> <type> <opts> <dump/pass>

# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.

/dev/BOOT /boot ext2 noauto,noatime 1 2
/dev/ROOT / ext3 noatime 0 1
/dev/SWAP none swap sw 0 0
/dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,ro 0 0
proc /proc proc defaults 0 0

Warning: Please notice that /boot is NOT mounted at boot time. This is to protect the data in /boot from corruption. If you need to access /boot, please mount it!

someone told me I have to type the command nano -w /etc/fstab instead.

going to try it tonight.

You didn't accidently mount the root filesystem as read-only or anything, did you? Of course, that shouldn't make it reply permission denied, but stranger things have happened.
I assume that you get permission denied when you actually try to save the file, right?

[skyfolly]

eh, fstab problem solved
now is the network!
i think i'd better give up on gentoo, ha ha ha
hm, need to do more learning

[Dolda2000]

Why give up? Trial is the best way to learn, isn't it?

[skyfolly]

he he, pessimistic, right? hm, well, As I said before, Gentoo Linux is not right for me since it takes too much time both installing and configure, and I am still not capable of Building a Linux system. I just tempted tried it out, I failed to install it for the first time, so I tried the second time, got it installed, able to boot into my system, but eth0 is down, various problems existed, so I leave it there, I always have a spare small HD(10G) for testing out, no harm at all.

Setting up the network is actually quite easy to do especially if you use dhcp. Just run dhcpcd eth0 and you are finished.
