How do I open my live cd? [Gnome]
« on: August 07, 2011, 02:18:04 PM »
 I tried the suggested easy way,but got nowhere.I don't seem to have the terminal commands correct. The terminal keeps saying not correct command.

I used:
alt-ctrl-F1

I got to terminal after login as root

I typed umount-a    
 clicked enter

got the incorrrect command fail

I tried umount space a

again incorrect fail

I'm very inept,do not use terminal commands,so It appears I need explicit step by step help.

I tried knowledge base also,it said entermylivecd in the root  terminal,I did and got a fail.

I'd like to make a dvd of my Gnome version.

Thanks

mylivecd is a console command, it is longer than just write mylivecd, there is multiple posts explaining details on the options you can use with the command on this forum

Hello, easy way. More easy there is not. → Alt+Ctrl+F1 : login as root, and type:
"umount -a (hit enter)"
"mylivecd ecoalex-date-of-the-day.iso"

before login to a tty, getout of your session : your cpu will thank you.

Conclusion : what is complicated about this ?

Hi,
You must comment out the tmp mount in /etc/fstab. comment out means that you will deactivate it, by placing a sign # at the beginning of the line, like this:

#tmpfs   /tmp   tmpfs   defaults   0   0


If you have other lines related to tmpfs in fstab comment them out as well, then reboot. Then try again.

Hi ecoalex,

you are actually using an old kernel: 2.6.33.7, unless you have specific reason to run this kernel, usually there aren't, update to the most recent kernel, 2.6.38.8-pclos3.

to use mylivecd with that kernel you need to specificy the option --lzma, because the default compression actually used from mylivecd is not supported from that old kernel.

About partitions and umount: you don't need to execute mylivecd from a terminal console, you only need to log out from the current user and then log in as root, still using the graphics interface.

open a console, and from there copy & paste the following commands:

Quote
umount   -a

verify what partitions remain mounted, (all partitions somewhat in use will and must remain mounted), using the command:
Quote
df -h

the max size you backup using mylivecd is around 10/11 Gb, not more.

I noticed you have a separate /tmp, please note that some area in /tmp is actually used when running mylivecd.

Also, if you are using a separate /boot, take care to not unmount that partition, or remount it, because it's vital for
a bootable liveCD iso.

AS

I just updated fully a week or so ago.I'm using a satellite isp.I'm on the verge of a slow down by wild blue.They call it bandwidth abuse.I'm in a rural area,it's all I have available. Thanks for the replies.I'll try to sort this new info out,but admit I'm ignorant to the suggestions.I have used various pclinuxsos versions for 5 years.I'm no whiz @ 60yrs. I will be the first to admit I'm ignorant using the terminal commands,or knowledge of the kernel or how it all works.I'm a farmer.I can explain how an ecologically based system operates in the soil.Thanks again for all who have attempted to help me.I sure wish there was an app to make a mirror of the system being used.Once upon a time there was.

There still is, and it's easier to use than ever. Texstar has seen to that. Just follow these simple instructions. Open a terminal. If you are using KDE, the application name is Konsole. Where you see [space], press the spacebar once. Do not enter extra spaces. Do not enter what is in parentheses. It's only there for explanation.

su [space] -
(enter root's password)
mylivecd [space] --lzma [space] --nodir [space] ^/home/yourusername [space] livecd.iso

There are only two lines to enter.

First line is su [space] and one dash symbol.

After entering that command, you need to enter the root user's password.

Second line is mylivecd [space] two dash symbols lzma [space] two dash symbols nodir [space] one caret symbol (which is a Shift-6 on your keyboard) /home/yourusername [space] livecd.iso.

Change yourusername to your actual username. It may be ecoalex, but I don't know. Your home directory will not be included in the livecd.iso file.

The file livecd.iso will be created in the root user's directory, which is /root. The procedure will run for quite a while. It's a good idea to do nothing else on your computer while it is running.

Backup your home directory separately.

I can explain how an ecologically based system operates in the soil.

So do I. I followed a professional teaching in organic agriculture a few years ago. (mostly for growing vegetables, in 1996-97)

You need just to follow what has been answered to you my AS, djohnston and myself. I looked at your screenshot and it appears that /tmp is mounted and busy. I explain : you cannot unmount the /tmp directory while the system is in use, because it is mounted on a virtual temporary file system : tmpfs (stands for temporary file system, I believe). The advantage of that is all the temporary files in /tmp directory are cleaned out (erased) at each reboot.

But in order to do the remaster you need to unmount it, otherwise it will be added to the iso, and as temporary files will be more and more numerous while the remaster is being created, the iso will become bigger and bigger until there is no space left in your system !

To sum up : you need to comment it out from the file /etc/fstab where it is written, the way I told you to, then reboot before performing the next steps (well explained by AS and by djohnston). This is the only way to unmount /tmp from the tmpfs file system.

PS: djohnston : if he excludes his home directory, his config files will be missing. Wouldn't there be a more interesting way to do things there ?

We don't know the size of his home directory. The DVD could exceed 4GBs in size. Probably the best way to do it is create a new account and copy his normal user's settings over there. But, the guy's confused enough already.
