SliTaz rolling: tazusb fails to create full rootfs.gz after cook setup

I am unable to create a proper rootfs.gz after executing cook setup.  The problem can be reproduced as follows

Starting with a clean slitaz-rolling-core.iso and create a live usb install (tazusb format --> tazusb gen-liveusb --> reboot).  Boot from the usb and do the following:

$ su

Password:

# cook setup

...

# tazusb writefs lzma

Write filesystem

================================================================================

The command writefs will write all the current filesystem into a suitable

cpio archive (rootfs.gz) usable on a bootable LiveUSB media.

Archive compression: lzma

Moving rootfs.gz to media. Remember to unmount for delayed writes!

My topic about tazusb is even on first page,  i had not exactly same problem(size was normal), but also after cooksetup, so after you ran tazusb open /tmp/list in any text editor with possibility of showing line numbers, and tell me how many lines=files+dirs is there. 65K is limit for rootfs. Cooksetup creates too many little files, each with own dir. Remember, that dir is also "file".

Edit post: wait, now I see "Creating rootfs.gz with lzma compression... Killed", this means - no enough RAM.  Do you have 512 or even 256 Mb? Use swap or linux-zram module with editing its size in tazpanel.

Good call @az_ua!  I did not know the significance of the "killed" message.  I booted in a VM with 1gb of RAM and repeated the process:

[c]# tazusb writefs lzma

Increasing the RAM allowed the successful completion of the operation.  Also, thanks for the tip on linux-zram module.
