Help a N00B with chroot

[More_Piffle]

Hello all,

I am rusty enough with Unix/Linux to call myself a Newbie, I know enough to get myself in trouble.

So I need to chroot into my funtoo installation so I can run: rc-update del xdm default    However when looking at the commands for chroot on the install instructions and I try to run: mount /mnt/funtoo/ I get no such directory. So I am thinking it is because I am booted to "rescue" and then I try to run: mount /dev/sdb3/ /mnt/funtoo/ and I also got no such directory. I ran: mount /dev/sdb3/ / and it seemed to work but when I changed to / and looked around at some of the files and directories I found that I was looking at directories and files on the "rescue" Linux.

I looked back in the instructions and they say:

   mkdir /mnt/funtoo

   mount /dev/sdb3 /mnt/funtoo

However I do not want to create a new directory I want to mount what is already there, so I did not do that.

As you can see I somewhat understand the commands and what I am doing but not really (my linux install is on sdb). I could use some help - even if it is "Hey you need to read this" - I will learn and want to learn.

 

What got me here:  Installing xfce4 after testing xwindows - the instructions say to edit /etc/conf.d/xdm and make these entries:

   DISPLAYMANAGER="<LightDM>"

   # rc-update add xdm default

   # rc-update add dbus default

   # rc

Finished up with the other instructions - created power group and added root to it etc. rebooted and did not get my xfce session as expected so not knowing what I was doing, and I seem to remember from somewhere years ago that # in a config file = a comment, I ran the rc-update commands at the command prompt and rebooted now I am presented with a login screen and can get no where and cannot get a command prompt.

@More_Piffle With the mkdir /mnt/funtoo, you are making a dir on the live disk so you can mount the directories that are on your root partition "/dev/sdb3." Then when you "mount /dev/sdb3 /mnt/funtoo" you will then have access to the files that you need to edit in "/etc/conf.d/xdm". Thus you are not making another dir on your installation /dev/sdb3. https://wiki.gentoo.org/wiki/Chroot

Oleg forgive me it is not a fault with any instruction, I figured out this morning, it is the fact that I used reader view with firefox and printed from there and so it looked like the rc-update commands belonged in the /etc/conf.d/xdm  config file. - I am learning by leaps and bounds ... Woohoo gonna get stuck in a corner again! Maybe not now, maybe not tomorrow, but I can feel it coming :)

The instruction that i followed that lead me to put # in my /etc/conf.d/xdm file is: funtoo.org/package:Xfce4-meta (it was because I printed from firefox reader view)

@tefreem34 Thank you for clearing that up for me, and thank you for the further instructions.

A picture of the area I am using to work on Funtoo, and all of the instruction sets that are now suspect because of firefox reader view and stupid users. Someone say a prayer for the trees!
