Following my success with testing aufs stacks in the "init" environment, I have a revised plan for updating the actual "init".

1. Cut search_func into 2, savefile/savefolder stuff becomes search_save_func
2. search_func is reduced to decoding all boot parameters and finding pup...sfs, setting PDEV1
if PDRVDEV is set:
if PDRVFN is empty set to PUPXXXSFS
if /mnt/pdrv$PSUBDIR/$PDRVFN exists, set PDEV1
else search for $PSUBDIR/$PUPXXXSFS as diligently as it was for "vmlinux", set PDEV1 if found
if PDEV1 set DEV1FS and other "vmlinux found" stuff
3. Remove all load sfs code from "LOADING PUPPY FILES" section
4. algorithm becomes:
do search_func stuff
load sfs's to pupmode=5 aufs stack
establish SAVEPART
do "insmod" stuff
do search_save_func
load savefile/savefolder
update aufs stack with savefile/savefolder
continue on to switch root
5. Complete change to use only a single tmpfs.
6. Cleanup more possibly reduntant code, e.g. setting the aufs layer variables in beginning of "LOADING PUPPY FILES" section.

As this has now become a coding exercise, when I have a modified "init" I will open a thread in "Cutting edge" for discussion of the code.

To encourage others to contribute, it might be handy to do this as a file on git-hub in a repository to which I, and others have direct access.
I'm not sure how to set that up.
@jlist, I don't have direct access to the initrd_progs repo.
At the moment the only git-hub repositories I have direct access to, are the forks in my git-hub account.
By "direct access" I mean something I can push "commits" to, using git on my local machine.

Ok gyro, initrd_progs is somewhat restricted to members of the team, those who have write access to all woofce repos, well, everybody else has to open pull requests ( just like i used to).

I'm certainly quick to merge pull requests so that could be the place, i also think you should a member, or at least have write access to that repo, i'll send a message to micko..

Well, this is what I used to do.... add commits then open a pull request every few days with all the commits... while the pull request was open i kept adding commits to document the changes.. initrd_progs is a place to experiment and push anything and that's what i did until it was ready....

I would suggest starting from this:
https://github.com/landley/aboriginal/blob/master/sources/root-filesystem/sbin/init.sh

Its pretty simplified already, but it unnecessarily parses /proc/cmdline - the kernel passes parameters of the format *=* to envp/environ (environment variable in shell) and other parameters without an equal sign to argv ($@ in shell)

In shell you can use a default variable parameter like this:

@technosaurus,

I'll look at that "int.sh". I'm still considering how to do it.

Concerning "searching", I tend to agree, so I want to make it quite direct when things are specified.
Unfortunately for mainstream puppy, removing "searching" altogether is probably a bit too radical a step.

@jlst,

How about I setup any interested folk as collaborators to my fork of woof-ce?
Then do a pull-request every so often.

[jlst]

I'm ok with that

The current "init" tries to be too "friendly" in what it does when a specified partition or file is not found.
If anything is specified and not found, "init" should act as though the file is not present.
It should not fallback to the default file, and use that, as the current "init" tries to do.

Why?
So that you get immediate feedback that the spec is incorrect.
If you're specifying an alternative sfs to test something, and it boots fine. The obvious assumption is that the test sfs is fine.
But if there is a typo in your spec, and "init" used the default sfs instead, then your assumption is incorrect.
You're more likely to notice if the sfs is missing from the boot.

(Of course it also makes the code simpler.)

unfortunately bloat is necessary .
there are too many possibilities of HW configurations available,
so testing needs done.

I have my own init code to speed up the search.
My init code accepts parameters like sfsload=oldsyle|new that is to load the sfs
and lastly the puppy.sfs and zdrv.sfs ;
and pupmode=X to force a pupmode and if X is something unknown falls back to 5 something like that ; instead editing the init to change 12 to 13 and such .

But I rub fukk installs on pupmode 2 mostly.
I wish you good luck

That leads us to kernel-kit and the huge kernels already built. When compiling a kernel, one needs to be sure that all (or almost all) modules that have to do with keyboard input are builtin.. if a huge kernel does not comply with this, then it should be deleted immediately...

[jlst]

gyro, watching the logs I see vercmp complains about a wrong syntax... i made sure the busybox vercmp works the same as the standalone app.

This happens when one of the operands is empty, so I wonder if there is something to delete there...

[jlst]

i think we should use the full blkid in the initrd, it's just more robust at everything, but a bit slower too
