[Solved]T weaking KDe for Less Powerful Computers

[T6]

yes, brand matters, sony, imation, tdk, samsung, hushkee are recommended

other brands can be ignored or avoided, bad surprises like not recognized by the drive, wrong speeds when burning, convert them into coasters basically, princo is popular for this

i tend to avoid optical media like the pest it is now, slow, limited in size and delicate

size and benefits also terrible

i only use a dvd-r or a cd-r when required, to burn a iso for example, or to share some pictures with friends and family(to watch them in a dvd player)

[Just17]

I recall a post from old-polack which said something to the effect that one type is much more reliable than the other (+ or -).

I would suggest searching for the post .....

OK, I searched and old-polack says the DVD word a lot of times but I missed it if he said which one is preferable. 

But then I never have had any luck with searching. 

I have successfully used both  DVD+R and DVD-R discs.

I did a quick search this am ....  and failed to find what I recalled .....  but did find that o-p uses
CD-RW and DVD+RW discs for the most part.


These are rewritable disks .....  which means you can burn an ISO today, use it, and tomorrow burn a different ISO on the same media and then use the new ISO.

I believe a couple of DVD+RW discs would be of more use than a bunch of DVD-R (or DVD+R) discs.

If you take a remaster of your install and burn it to a DVD+RW you could take a new remaster in a few weeks time and burn that over the older remaster on the same DVD+RW, thus always having an up-to-date remaster on hand

......  without the clutter of outdated and generally useless read only optical discs. If you wished you can save the remaster ISO files on HDD if you wanted to keep them available for use.

Just a slightly different approach.

regards.

That's DVD+RW, not DVD-RW.

DVD-RW need to be erased before re-burning, whereas DVD+RW are just written over, without erasure.

I now have 50 DVD -R.

Hello ms_meme,

I now have 50 DVD -R.

Great! In the meantime I have done a couple of tests using mylivecd: I will provide the instructions below. Approx. you will need from half an hour up to one hour to complete the ISO creation. (Thats are my precise calculations    )

log in as root: open konsole and copy & paste the following 3 commands:

Code: [Select]

echo "mkdir /home/temp 2> /dev/null" > /root/my-iso.sh
echo "mylivecd --lzma --tmp /home/temp --nodir ^/home/temp /home/ms_meme.iso" >> /root/my-iso.sh
chmod a+rx /root/my-iso.sh

once you have executed the above commands, the following will perform the real work:

Code: [Select]

/root/my-iso.sh

if all will work as expected, an ISO image of your system should be found under the directory /home, named ms_meme.iso

Next will you will need to burn the ISO image to a blank DVD-R, using K3b or something like.

Any question ?

Yes, I do have questions.  I just don't know what they are.  Definitely not questioning what you told me to do.  I will leave that to the other forum experts. 

But I do like to have an understanding of what I am doing....even if I don't understand completely. 

I have been reading/scanning some of the posts regarding MyLiveCD etc.  And of course could never follow it.  But I am looking for some instructions of what to do to prepare to make the iso.  Surely there must be something that says, "Make sure you do this or that."

As I understand it.....I am only going to make a copy of / ?  Nothing in the /home or DATA partion will be on the iso?

What if my / is not like I want it?  (I have no idea how I want it!  Just asking?)

We made some changes when looking to lessen the burden on my RAM.  I know many of them were related to KDE so probably won't be affected?  But some were made.....maybe to the system?

I thought I read someplace about using Bleachbit first?

This iso will include all the Synaptice updates?  That is to the / part?

What will this iso have besides my name of it..   that I wouldn't get my just downloading the new 2011?   I guess my iso would have that old kernel?

I sound like my kids asking questions when they were little.    And I would have to say, "Stop asking questions and do what I tell you to do!"

Your /home is included

What if my / is not like I want it?  (I have no idea how I want it!  Just asking?)

If you have all your apps installed then it is as YOU want it

Yes

All the updates and extra apps, as well as any changes you made to the Desktop environment to suit your way of working.

I have already done all that for you: now I try to explain:
your '/' partition has no sufficient free space (or it's near to be insufficient) to build the live ISO there, so the command
was prepared to build your ISO in a different place, /home, where there is enough free space.

Additionally, depending on kernel version some type of compression can be used, some other not, --lzma is the correct compression for your running kernel (2.6.33.7-pclos6).

Finally, because ISO must be created from time to time (and you need to use some of that 50 DVD-R  ) all mylivecd parameters
are saved in a single script, so that whenever you will want to do it again (may be next month or so...) you will simply need
to run the script from root user:
/root/my-iso.sh

As I understand it.....I am only going to make a copy of / ?  Nothing in the /home or DATA partion will be on the iso?

Actually ALL your system, including /home will be included into the ms_meme.iso image.

What if my / is not like I want it?  (I have no idea how I want it!  Just asking?)

'/' contain your system files, building an ISO without '/' mean to have an ISO that cannot boot!
Must be always included.

We made some changes when looking to lessen the burden on my RAM.  I know many of them were related to KDE so probably won't be affected?  But some were made.....maybe to the system?

Nothing is going to affect the normal operations, only some service has been disabled or some accessory program.
I have tested the ISO creation in my virtualbox that is actually a replica (from a configuration point of view) of your system, because every tweak that was suggested has been previously tested on my guest machine 

I took a lot of care to not broke your system 

I thought I read someplace about using Bleachbit first?

Of course, BleachBit is a cleaner, that help to remove unneeded files, however it's not critical in your case, right now.
Nothing prevent you to run BleachBit before to execute my-iso.sh script ! 

This iso will include all the Synaptice updates?  That is to the / part?

Yes, it will be a copy of your current system, all included.
The only things not included are temp files (which you don't need) and some hardware configuration files, that however should be properly rebuild upon ISO restore. (like sound...)

Anyway, once you have created the ISO, you should be able to boot it and test how it will run.

What will this iso have besides my name of it..   that I wouldn't get my just downloading the new 2011?   I guess my iso would have that old kernel?

All the updates, all the already applied tweaks, all your personal data, of course your current running kernel.

I sound like my kids asking questions when they were little.    And I would have to say, "Stop asking questions and do what I tell you to do!" 

Let me add that the overall idea of a liveCD, is because if i.e. your HW should die, you can recover all your system and data.
Simply insert the remastered ISO in a different computer and you will have your current system/software/data.

I'm sure you forgot something else 

BTW, Thank to Just18, always faster than me

I didn't know all my folders and files/pictures/nonsense_stuff would also be copied.

Then really I should consider this as an exercise to see if it works.  I have no doubt that it will!!!   
And if it doesn't, I do have 49 more. 

I will do 2nd thing tomorrow.

No more questions.

I am about to begin.  One more question...    Once it starts, can I do other things?  Or do I have to wait?

No, leave it go alone.
Also let all applications closed (other than the terminal console). This process is resource hungry, most likely it would sluggish all other opened applications  Especially on your low RAM system.  Also you must log in as root, not your user account.

I forgot to say that the overall process actually refer to your KDE installation, not Phoenix-XFCE.
XFCE partitions will not be included in the ISO.

Yeah, right!

I forgot about, because it's always installed on my systems 

please open synaptic, install draklive-install, then retry.

[Just17]

Just to clarify ......


you only need to run the last command after installing draklive-install.

So after installing it, in a root terminal the only command you need is

/root/my-iso.sh


The previous commands were issued to set up that command and do not need to be done again.


good luck
