 :idea: Iso boot files on multisession usb saving space. |
|
Ok i have just found out that its possible to Boot directly from an iso file. i am wondering how puppy will run if doing this vrs conventional Frugal setup.
Here is what i usually do
- Creat a folder for the puppy
- mount iso or open cd
- copy the 3 files needed, initrd.gz, vmlinuz adn the (puppy).sfs
- point boot loader config to them
Main idea behind this
My main idea would be to set up and boot many puppy os from iso on a usb device saving space setting up each frugal puppy separately. also coudl boot other os this way. I guess this has some valid reasons to do it or not.
The current boot loader you have would need to be able to boot from iso files. and setup to do so.
is there any benefits to iso booting vrs conventional hdd frugal install.
edit After my continuing to use puppy i found it easier to do a frugal setup. so i never really pursued this idea. edit

I don't think it matters which way you boot. Obviously booting from ISO on CD might be slightly more inconvenient if you use the CD drive a lot for other things.

I have found out that the iso might have to be configured to do so. although this is not exactly true in all cases. |
It does matter how one boot. Many Linux distros has a built in restriction of permissions in relation to "Live Session User"
I tested Vector STD Gold the other day and did a frugal install
and it does not allow me to even access the drive it booted from.
Similar with Debian distros like Mephis or AntiX or ... LMDE also being Debian none of them allow one to write to the partition them booted from. Them allow read only.
So it does matter for a lot of distros.

Well, Puppy is designed to work as a properly burned live CD, frugal or full install. So, only way to know for sure, is try it.
Never have understood why people want to make an operating system work out of the normal designed way.
I ques just to see if you can.

A good reason would be to have fully portable OS on a USB in that
you only need to change the iso and not do any install what so ever.
You just change the menu.lst or grub.conf for the new iso
and it boot and do everything you need.
But maybe I help us derail the thread.

It is a valid reason it woudl save space on teh flashdrive. which was my origional thinking. then again i never really tried it. it was just an idea i put out to see if it got interest.

Wow or Voi!
Don't you want to share how you did it.
The menu.lst or .cfg something.

I do that sort of thing!
Here is a copy of my menu.lst:

# This is a sample menu.lst file. You should make some changes to it.
# The old install method of booting via the stage-files has been removed.
# Please install GRLDR boot strap code to MBR with the bootlace.com

Nice one thanks for the Info its great.

Thanks
I wonder about this one.
| Quote: |
1.) The old install method of booting via the stage-files has been removed.
2.) Please install GRLDR boot strap code to MBR with the bootlace.com
utility under DOS/Win9x or Linux. |
Do we boot using the the stage-files now? Is that in legacy or grub4dos or?
So bootlace.com utility has come up with some code that solve it?
Why are some in small letters and some in very big capitals like
vmlinuz and then suddenly VMLINUZ What is the purpose of that?
The whole thing can be of help for somebody to get a hang of what is going on.
So much appreciated
Using google I found this
Grub4dos Guide - Configuration File Entries
diddy.boot-land.net/grub4dos/files/menu.htm
The old install method of booting via the stage-files has been removed. # Please install GRLDR boot strap code to MBR with the bootlace.com # utility under ...
But something with the server or they have movedthings around
because page times out

For those who may have wanted to understand why one would want to do this, consider this scenario.
Let suppose that you have a library of ISO (this generally occurs if you are assisting or testing differing PUPs for distro developers and the community.)
After download, it would be nice if there is a way to simply update the boot manager, pointing to the ISO's location, and boot that ISO without going thru ANY other approaches. The intent is that it would be a time saver and you won't have to burn CDs (assuming you understand and use Live media) Thus, excepting for the normal downloading to a location, almost NOTHING is needed to at least boot and observe the Puppy distro behavior. And, excepting the download space impact, there is NO other impact to the system storage. None.
This is tremendously beneficial...tremendously (if its at all possible, which I understand it is, and reasonable.)
@Flash, several years ago, was looking at this. He also is a premier resource for everything "Live", as in Live media operation with his knowledge of CD/DVD writing issues.
Hope this helps

That is because the file name is case sensitive and therefore has to be the same as that on the disk.

I take it you mean within the ISO or do you mean on the Booting media as its referenced from GRUB4DOS?
Thanks in advance
