Now I have booted racy-5.3 in PUPMODE=13 frugal installed on SDCard flash :

"mount |grep tmp" gives :

tmpfs on /initrd/pup_rw type tmpfs (rw,relatime,size=1303776k)
tmpfs on /initrd/mnt/tmpfs type tmpfs (rw,relatime,size=111640k)
shmfs on /dev/shm type tmpfs (rw,relatime,size=192808k)

where all folders on '/' inclusive /tmp are mounted also as /initrd/pup_rw, the top unionfs|aufs layer , so apparently no need to mount the main /tmp folder another time separately . Will have to check if the /tmp folder gets copied to the save file, which i think it shouldn't.

The main puppy_racy_5.3.sfs is copied to /initrd/mnt/tmpfs/ directory :
ls /initrd/mnt/tmpfs

A: puppy_racy_5.3.sfs

The devx is not copied to ram .

The save-file is now mounted as :

/dev/loop1 on /initrd/pup_ro1 type ext3 (rw,noatime,errors=continue,barrier=0,data=ordered)

It is a little confusing to call the savefile pup_ro1 : as far as i saw the code, the save-file does not get remount,ro 'ed and remount,rw 'ed when snapmergepuppy is running or when the save at rc.shutdown is made.
The save-file is mounted rw all the time . (A possible risk imho.)

free shows :

Mem : 1025472 total
Swap: 1582076 total

(have disabled one swap in rc.sysinit to be reserved for Resume from Hibernation (which is not possible with stock Puppy kernels by Bk but from pemasu fex.)
