The following are patches to "init" and "rc.shutdown" against TahrPup 5.8.3.rc1,
that implement 'savefolder' using symbolic links instead of 'mount -o bind'.

Patch 1) "init" script in "initrd.gz":

Will this work with a multisession Puppy DVD?

I remember that there was an option to do a sort of hybrid install where the install itself was frugal but you could save to / and (theoretically) not have to bother with savefiles filling and all -- it would fill the remaining space in the root partition with savefile goodness automatically, or something like that.

Unfortunately it was abandoned before it became functional, and eventually it got removed. The few times I've tried it, as soon as I rebooted from the first boot, Puppy would make a mess on the carpet and generally not work. I don't recall the exact details but it was lots of red text having to do with one of the pup_ro bits (I want to say ro2?) followed by a kernel panic.

I would love to see that option actually made functional and brought back as such. Would make Puppy just that much more easy to use! (I wonder if it could be implemented simply as "put the savefile in / rather than a folder, and fill the entire partition with it"?)

Great. Seemingly plays into the hands of "remaster this very system".

bind mount was used for the save folder to avoid altering the pup_rw folder arrangement to keep compatability. Also its puppies ill thought through scripts unable to deal with it that was the problem rather than something wrong with the technique itself.

With any addition/modification to save techniques the designer has to try and keep everything as-is as much as possible otherwise you would need to change the name to Porteus or something Very Happy

I dynamically created additional folders for extra sfs but still keep pup_ro2 for exactly the same reasons. Certainly rearranging the initrd structure would make life a whole lot easier at times but compromise is the key word here.

Url's for downloading an initrd.gz and ydrv for TahrPup 5.8.3.rc1 are now included at the end of the first post.
The ydrv contains sfs_load, to avoid partitions remaining mounted on first boot. (It's fixed in QuickPet, but that's too late for first boot.)

I have attached the diff files I used for Dpup Wheezy 3.5.2.11.
I have also attached my utility for converting an existing savefile to a savefolder.
The files are really gzipped, so download and move them to where you want them and then gunzip them.

I post these as an example of porting this savefolder facility to puppies that are not based on a current version of woof-ce, as TahrPup is, and hence do not contain any savefolder facility.

Warning, while this version of savefolder avoids the "more than 1 mount entry" problems that plagued the development of the bind mount version, it does not make any difference to other problems.
Example: when I previously ported savefolder to Dpup Squeeze Exprimo, the "rc.shutdown" would fail. I expect that this version could have the same problem.

Note: Once I have sorted out the easiest way to include an updated 'shutdownconfig' I intend to upload a patched 'initrd.gz' and a 'ydrv_wheezy_3.5.2.11.sfs' containing 'rc.shutdown' and 'shutdownconfig'.

Note2: I have included 'savefile2dir' because without an updated 'shutdownconfig' you can't create a savefolder. But this utility can convert an existing savefile to a savefolder. So testing of the savefolder facility can begin once you have a successfully patched 'initrd.gz' and 'rc.shutdown'.
