How do I get my settings to be saved on shutdown?
KLV-Airedale-beta26

grub.cfg:

menuentry "KLV-airedale64" {
  insmod fat
  search --no-floppy --fs-uuid --set=root A593-8174
  linux /klv/vmlinuz w_bootfrom=UUID=A593-8174=/klv w_changes=RAM2 net.ifnames=0
  initrd /klv/initrd.gz

Cannot run save session on demand
Directory /mnt/layers/us_ro not connected ___ how to connect it ?

I have not seen this error before. I will have to test some RAM2 runs!

Probably you need to have a save file (as it seems to be on FAT filesystem) and point to that with w_changes=.. (cannot be sure how exactly tbh)
On e.g. ext4 filesystem save folder use is possible.

Yes, if wanting save persistence to a FAT or ntfs filesystem you need to manually first create a Linux formatted savefile called upper_changes.ucimg (actually any savefile name will work as long as extension is .ucimg).
The extension is important (.ucimg). The KLV initrd init code will notice it and use that savefile in preference to any save folder. If there is more than one savefile only the alphanumeric first one found will be used.

I haven't myself made any savefile creation utility, but just used dd. I documented about that here: https://www.tinylinux.info/post/firstrib-savefiles/

Thank you all for your help, everything went well, the save is working.

This very useful information https://www.tinylinux.info/post/firstrib-savefiles/
Reconfigured to my language
I now have a KLV-Airedale-beta26 - XFCE puppy with my tongue

It's very good that the save files have a different format, this allowed me to install two different puppies in one place
vanilladpupsave-sofiya.4fs - VanillaDpup
upper_changes.ucimg - KLV-airedale64

Here is just one question how to see how much space is left in the save file. " upper_changes.ucimg " .after saving ?

Sorry I don't understand. Is the above a question? If you don't have the w_changes=RAM2 in the grub.cfg then you are not wanting to use save persistence. Rather the default direct writes to install directory upper_changes folder will be used since RAM is not being used in that case for session work.

NOTE: The w_changes1=RAM2 alternative is for a special case where you want save persistence file or folder to be in a directory other than the one you boot from since in that case you use the main "w_changes" kernel line variable to specify the location of where you want persistence file or folder to be (using normal UUID or LABEL type line such as w_changes=UUID=XXXXXXXXXXXXXX=/wherever followed by w_changes1=RAM2 to tell the initrd to use save persistence mode with that previous w_changes save location; i.e. via that mechanism you can put save file or folder anywhere you want to on your system no matter where you boot from).

Personally I am just maintaining the initrd to provide the capability of that upper_changes.ucimg savefile support. To determine how much space is left in the save file (or indeed also a convenient way to make new savefile) you or someone interested to do it would have to write a utility to check that. Maybe rockedge could add that to a KLV-Airedale todo list? Probably not main priority at the moment though since most reports have been from those using save folders not save files, but definitely a good idea to have a check space of savefile utility. In a way, that is one of the points of KL being community distros - to encourage and allow participation and useful additions per user feedback and contributions. Having said that, since the upper_changes.ucimg file gets mounted you can use command:

df -h

to provide information on size and amount used. But a system script could for example provide warning, for example, when savefile almost full.

The foregoing is not a question
