More remasterme problems

[gezza]

Hi guy's
I have a system with 7.5GB used 12GB free and the system requires 5GB of free space.
All seems fine so why does remasterme fail: See Next---
ws1 Documents]# remasterme --nodir=^/mnt --nodir=^/home  --lzma
This script tries to remaster your current install.
The iso will be created as pclinuxos-2010.iso
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1              22G  7.8G   13G  39% /
/dev/sda3              22G  7.7G   14G  37% /home
You try to remaster 15 Gigabyte install.
***I would have thought this should be 8GB install
You need at least 5 Gigabyte freespace
The free space avaialable for remaster 12 Gigabyte
mylivecd, version 0.9.1, http://pclinuxos.com/

This happens unless I keep the installed size to below 6GB.

The system needs /home. You can't use the option --nodir=^/home.

First use this command:

Code: [Select]

umount -a
This command unmounts all partitions except those you are working from.

Then use this as your build command:

Code: [Select]

mylivecd --nodir=^/home/your-name name-you-want.iso
To exclude your personal home directory, you need to specify your /home/username. Excluding all of /home will fail. As mylivecd uses lzma compression by default now, the --lzma is not needed.
 
There are only two elements needed in a remastering command now, the command mylivecd and the name of your iso. If you need to exclude your personal /home directory, do it as outlined above.

Hi Gezza,
I do a similar remaster as you. I have a Vbox drive in /home that I don't want in my remaster. But leaving out /home/myself results in an ugly (IMO) desktop. So I create a guest user, enable autologin for guest & ^nodir other users.
Just did a remaster with a similar command to Neal's using my guest action & got a beauty!
hope it's a help.
Have fun!

Hi there, johnmart
Many thanks for that reply, it does sound that it gets round my problem

Glad to hear it Gezza--maybe edit thread title <solved> --

Hi johnmart
Well I have tried your method and on this machine I still get the same results.
a divide by zero.
So Your method does not work for me.
I have noticed that even when I create a second user say a guest, remasterme still says the /home folder is the same size. In my case 500MB
I am told that I am remastering some 10GB os software and I will need some 3Gb of space on a drive that has 30Gb free.
I still do not understand why the mylivecd cannot find the iso it is supposed to have created in /root. If it did not create it why on earth not?
I have not solved this problem yet, so any other thoughts greatfully received.
By the way i just used 'remasterme'

You haven't tried the method Neal outlined? Note, he recommends using mylivecd , not remasterme .

The system needs /home. You can't use the option --nodir=^/home.

Code: [Select]

umount -a
This command unmounts all partitions except those you are working from.

Then use this as your build command:

Code: [Select]

mylivecd --nodir=^/home/your-name name-you-want.iso
To exclude your personal home directory, you need to specify your /home/username. Excluding all of /home will fail. As mylivecd uses lzma compression by default now, the --lzma is not needed.

gezza,
Use the command I posted previously. There have been changes in the mylivecd program that make using that script an advantage for you.

mylivecd --nodir=^/home/your-name name-of-your.iso

Note that it is basically a simple script with a command,

mylivecd

and an object of that command,

name of your ISO

These two together will create your ISO.
 
As you seemed to want to not include your /home directory,

--nodir=^/home/your-name

is added as an option to the command.

Hi gezza,
I didn't read your IP carefully enough to understand your problem clearly.
Actually "my method" was just an addition to Neal's advice as you were trying to leave your user off the remaster.
I think you need free space on your / partition for a temporary copy of your iso.
According to your mylivecd feedback in your original post your remaster is 15gb so requires at least that much free space on /. If you left off youruser, you still are short free space on / for the temp iso.
You should find some specific info on necessary freespace in the sticky threads at the beginning of this section.
Remember the new remaster command is mylivecd (plus options, like Neal said)--many threads refer to the old version.

A few tips:
1) Add the total amounts for all partitions under "Used." If they exceed 10GB, you need to move your files to a backup partition or CD/DVD(s) or exclude some directories and / or sub-directories from your remaster.
2) If you have had a previous remaster failure, check /tmp for anything left over and remove anything that was left.
3) Make sure that you have installed draklive-install.
4) Run bleachbit and bleachbit-root. Cleaning up your system helps reduce its size.
5) Open PCC > System > Manage system services by enabling or disabling them and uncheck the Start on boot for anacron, atd, crond, syslog and kheader. These services are not needed on a liveCD and will be re-enabled on first boot after installation.

Hi,

For this one Texstar said that is was now done automatically by mylivecd (on one of the mailing lists).

No problem. You're a geek, not a bot !

That's a good line. And so apropos.

Hi to all,
I have reduced my install file to bring the backup size to below 9GB as recommended but now I have lost almaos of the icons in the task bar and most programs are not displaying information correctly!!!!
What do I need to replace to get these back or do I do a reinstall?
Many thanks.
