Takes quite a long time to load the SFS.

What is the PUPMODE? Full install?


Good morning shino,

Frugal install, or, more precisely running from live-cd with save file.

Bert

Would it be possible to patch the bootmanager to do this?
I think a new and improved bootmanager would be less confusing than two boot managers.

I agree. The bootmanager can be modified or replaced when we are sure this method is stable.


Excellent! I will add this to the next release of Fluppy to get some more testing.

Great idea. I hope Barry considers adding this functionality to woof.

I think the update layered filesystem part of the init script does some stuff with whiteout files. I guess in cases where there is a conflict a reboot would still be needed but most of the time, I think it'll be no problem. It may also work to clean the whiteouts on a mounted filesystem - but that would need to be tested.

Works OK now with or without pupsave, but maybe it should run fixmenus after unloading SFS to remove menu entries of unloaded SFS. Tested on Wary-5.0 (original and multilingual).

Hi shino

Tiny syntax error (v2) at line 124
Code:
case "$M" in
  info|warning|error|question) MARK="dialog-$M";;
  *) MARK="$M"
  esac

should be
Code:
*) MARK="$M" ;;
I think

Cheers

Right. I am wondering why the sfs_load does not. Checking it up more...
EDIT: Got it now. Smile

@01micko. Thanks for the debugging.

Both will be fixed at next release.

As I like the sfs method, on my 128mb toshiba, I mainly use choicepup 4.1.2 cd with jrb's pre installed "open with sfs load/unload" and sfs 412 on usb.
Simultaneously I use your pupsaveconfig, pupsave=-0 (never) pupmode =13 .
When I tried yours, it said "failed to append "initrd/pup-ro4" to unionfs. "x-sfs moved to initrd/mnt/dev_save"
Maybe cause jrb's is already in there ?

Confirmed the sfs_load does not work with Puppy-4.2.1.
I can manage it and will be fixed at next release.

This increases the attractiveness of separating out seldom used apps into their own SFS. (or theme/task groups).

UPDATE:
30 Jan 2011 v0.3: unionfs mount option, fix menu update after unload
Supports Puppy-4.2.1.

EDIT:
Also tested on 4.1.2 and 4.3.1.
That is, tested and works: Puppy-4.1 through 5.0(wary) and 5.2(Lucid).
But seems not work on Puppy-4.0.

Aaaaah, that's what I was waiting for...

I am in the middle of testing other things, so cannot install this one yet, so have a few questions:

1. How does this differ from the otf-sfs-loader by goingnuts? Does it use the same method?
(Because the goingnuts otf-sfs-loader doesn't work in puppy 5)

2. Does this allow users to change the maximum number of loops available - so that users can choose how many SFSs are loaded on the fly?
(Very useful!)

3. Have you added ROX right click options for SFS files to load them?
I did it in Puplite, it is very convenient!

3. Do you check for incompatible SFS version, and load Trios SFS convertor, if it is installed?
(That would be great, I will do it in Puplite.)

4. Can I load a 200mb SFS file on the fly, using only a 128mb save file?
(Because when using the goingnuts otf-sfs script, the size of any SFS file loaded on the fly must not be larger than the free space in the save file, during initial unsquashing...)

Sorry for all the questions!

Basically same method i guess. The sfs_load is designed to keep the compatibility with traditional bootmanager.
Of course there are small tweaks matching with Various Puppy versions. The sfs_load is tested on Puppy version 4.1 through 5.0(wary) and 5.2(lucid).

No. The sfs_loader keeps the compatibility with the traditional bootmanager and has same limit.
Barry thinks too many layers to the unionfs slows down the performance.

EDIT: sfs_load-0.9 and later supports sfs more than 6(experimental). I don't know the upper limit Wink

Yes.

Yes checking, but does not have the button or launcher.
I think the sfs version converting is not so easy for beginners.
It consumes large space and requires Linux partition or work space.

Yes, you can. Well... i wonder why the goingnuts otf-sfs cannot. Maybe for the auto converting the sfs version?

I know what you're feeling about this. That being said, can I persuade you to implement a "non-persistent" SFS loading beyond the traditional 6 SFSes limit? Yes I know it may be slow - you can include a pop-up warning etc when a user tries do this - but it has its uses, especially for testing multiple SFS-es ==> however slow it is, it's still faster than a reboot, and some of us can live with the degraded performance. Especially since the newer kernels have dynamic loop devices (for older kernels, you can disable this functionality).

For your consideration. And thanks for this.

cheers!

When I choose sfs-file from the pulldown it doesn't work, but works OK with drug and drop into the field 'Which sfs do you want to load?' More info on the picture. (Wary-5.0)

Worked nicely in Lucid 5.2 with an extra.sfs package that contained apps/files from remastered lucid_520.sfs. Apps installed/uninstalled without rebooting, and worked fine. After uninstalling, a few empty links remained, but it got everything else. Thanks shinobar...very useful utility.
