Is there a way for me to apply a "...delta.iso" to the main ".iso" while using any other linux operating system (say, Debian or whatever)?

The program is xdelta3
Available for most linuxii
https://pkgs.org/download/xdelta3
Code:
# xdelta3 --help
VERSION=3.0o
usage: xdelta3 [command/options] [input [output]]
special command names:
    config      prints xdelta3 configuration
    decode      decompress the input
    encode      compress the input
    test        run the builtin tests
special commands for VCDIFF inputs:
    printdelta  print information about the entire delta
    printhdr    print information about the first window
    printhdrs   print information about all windows
standard options:
   -0 .. -9     compression level
   -c           use stdout

memory options:
   -B bytes     source window size
   -W bytes     input window size
   -P size      compression duplicates window
   -I size      instruction buffer size (0 = unlimited)
compression options:
   -s source    source file to copy from (if any)
   -S [djw|fgk] enable/disable secondary compression
   -N           disable small string-matching compression
   -D           disable external decompression (encode/decode)
   -R           disable external recompression (decode)
   -n           disable checksum (encode/decode)

   -A [apphead] disable/provide application header (encode)
the XDELTA environment variable may contain extra args:

   tar --use-compress-program=xdelta3 \
       -cf target-x.z.tar.gz.vcdiff target-x.y/
#



Well, I've tried to read (for the past hour) how to correctly use "xdelta3', but the documentation is not very clear in my opinion. The only thing I could get to run is showed in the pic below---and I do not believe it can be right because it took less than 2-3 secs to run, and the resulting 18.03+4.iso is only ~2.8MB larger than the original 18.03.iso.

Yet the .delta is 57MB in size, and when you do it inside a puppy, it definitely takes longer than 2-3 seconds for the delta to apply & then generate the new .iso.

Can anyone give me some hints on exactly what to enter into the terminal? I've tried the "-d" command paramter, and also "djw -S" parameters. (Fred, you out there??, I am in my XFCE-Debian64-build trying to do this)

About right....check the md5 of the generated .iso - shown above?

Well, dang, the md5 sum you posted for 18.03+4 checks out exactly.

Hmmm, I guess something must have happened. But, I swear, Peebee, when I was in the terminal and hit the "xdelta3 -d...." command, it happened so fast I was like what? It was literally less than 2 secs & it spit out the new 18.03-4.iso. When I do them inside a pup, it's definitely longer than that.

Oh, I will keep pushing on here.

Going to now try the 18.03-5.delta on the 18.03.iso, and again try to watch what happens.


P.S. Thanks for posting about the xdelta3 being the program to use.

Could well be because you do it from 64-bit OS.

Hi Peebee,

https://sourceforge.net/projects/lxpup/files/Other/LxPupSc64/updates/

Applied "lxpupsc64-18.03.iso___lxpupsc64-18.04.iso.delta" and all is running good with 18.04. Resulting md5 iso checksum checks out too. Thanks for the update to 18.04!

Just as a side note, this lxpupsc64 of yours has been running for over 148 hrs straight on this laptop that we leave on 24/7 in the kitchen for everyone to use for any reason. Not one single problem, stable as heck, even when it's being banged on & also globbed on with tons of food, lol, by the little one's cooking experiments Wink

Mucho thanks.

New manual frugal install of LxPup64Sc-18.04 to 32GB SandDisk Ultra Fit Flash Drive. Running on Dell Latitude 3350 Core i3-5005U 8GB RAM

Working fine after manual fixes for some issues of missing firmware from fdrv.sfs for kernel 4.15.x:

- ibt-hw-37.8.10-fw-1.10.3.11.e.bseq not found (manually installed)

issues of missing firmware from fdrv.sfs

Hi TerryH

The topic of which firmware should be shipped in the iso is a thorny one....

I guess your laptop is brand new - "Dell v: A13 date: 01/23/2018"

I will add the 2 smaller items to the fdrv for future builds but iwlwifi-7265D-29.ucode is over 1MB so if it goes in something else has to come out - but what??

Cheers
peebee

Why? Rolling Eyes

I know we like to keep things small. But IMHO it is more important to keep things functional OOTB.

IIRC, firmware is packaged as a separate module > fdrz.sfs. Or at least it could be as all recent Puppies OOTB can load them on bootup. With Gbs (or, at least, hundreds of Mbs) of disk-space, several Mbs doesn't make any difference. Having unused firmware in an SFS uses no (or almost no) RAM. And there are firmware cutters to reduce firmware to only that being used. Or remaster.

I added 7 iwl firmware files to my remaster, to cover many newer intel wireless - 7.7mb. This is by no means exhaustive, so I see Peebee's dilemma.

PostPosted: Thu 05 Apr 2018, 23:03    Post subject: Actually, the dilemma is drivers  

As I said, one fdrv.sfs, regardless of its size is one download which can be used again and again in any recent Puppy.

The dilemma is drivers. They must be specifically compiled against the kernel of the Puppy being used ['though if I understand it correctly minor variations of kernels may not be significant. That is a driver compiled for kernel 4.1.30 would work under kernel 4.1.45, but not 4.2.30. But, even that may be wrong. And certainly, there would be, in any case, a hell of a lot of drivers to compile.

There is already a complete fdrv maintained by gyro which can be downloaded:
http://www.murga-linux.com/puppy/viewtopic.php?p=820573#820573
http://www.fishprogs.software/puppy/firmware-sfs/

The dilemma is what subset of this large fdrv (119MB) to ship included in the iso so as to satisfy most configurations (but not all). 20-25MB is about the right size for this subset (I think). Intel wifi seems particularly prone to needing new large firmware each time a new wifi chip is introduced and shipped with modern laptops....

The chicken and egg situation for wifi is that you need the wifi to work to download the complete fdrv and the wifi won't work until you download the full fdrv....so you need access to an older working computer when you buy a new laptop....

Following my earlier mentioning of missing firmware, I thought I'd kill some time checking which firmware is used by various kernels for Intel 7265 wifi card. This testing is meant to hopefully assist. Personally I don't use the fdrv.sfs, apart from testing. I have number of firmware files I manually instal to /lib/firmware as required.

I realise that it is a difficult decision which firmware versions need to be included. Intel changing the container version number, whilst the actual loaded firmware version is the same (refer tests for kernels 4.1 and 4.2) doesn't help. The Intel 7xxx wifi cards have been around for a while now, there are now newer Intel 8xxx wifi cards, which so far have not been catered for in puppy fdrv.sfs/zdrv.sfs.

Testing was done using my Dell 3350 Core i3-5005U laptop. This is a 2 year old laptop. I ran with kernels 3.18, 4.1, 4.2, 4.4, 4.9, 4.14, 4.15. This was done running lxpupsc64-18.04, except kernel 4.9, which I used Dpup Stretch 7.5 RC2. All runs were completed with manually updating vmlinuz and zdrv.sfs, while running with pfix=ram kernel parameter.

Kernel 3.18.22

Load of firmware failed after 3 attempts. Manually installed iwlwifi-7265-10.ucode after checking connection. Firmware version 23.15.10.0 was contained in file iwlwifi-7265-10.ucode. I have noticed this seeming mismatch with several iwlwifi firmware versions. Makes it hard to know which firmware you are actually running.

The fdrv currently includes:
Quote:
iwlwifi-7265-10.ucode iwlwifi-7265-9.ucode iwlwifi-7265D-10.ucode

10 and D-10 look to be useful from the above analysis but maybe 9 could be deleted? and D-10 can apparently just be a link to 10.....

the full gyro fdrv has:
Quote:
iwlwifi-7265-10.ucode iwlwifi-7265-9.ucode iwlwifi-7265D-21.ucode
iwlwifi-7265-12.ucode iwlwifi-7265D-10.ucode iwlwifi-7265D-22.ucode
iwlwifi-7265-13.ucode iwlwifi-7265D-12.ucode iwlwifi-7265D-27.ucode
iwlwifi-7265-16.ucode iwlwifi-7265D-13.ucode iwlwifi-7265D-29.ucode
iwlwifi-7265-17.ucode iwlwifi-7265D-16.ucode
iwlwifi-7265-8.ucode iwlwifi-7265D-17.ucode

and it looks like D-22 should be added?

Then 8265 has been mentioned....the full gyro fdrv has:
Quote:
iwlwifi-8265-21.ucode iwlwifi-8265-27.ucode
iwlwifi-8265-22.ucode iwlwifi-8265-31.ucode

should one of these - 27? - be added?

Thoughts? Or should I just do it and see who shouts Confused
