When i say mirror sync it's for grub2-efi-x64-modules packages.
Infact i don't rebuild iso since May 27th ;)

So to be clear I use the same iso to install with?
Can I use the rolling iso for this?

yes you can use same iso current build on May 27th.
grub2 and other packages related (grub2-efi-x64, grub2-efi-x64-modules) not include on iso

rolling and current has not the same stack.

cooking/rolling
glibc 2.14.1
kernel 3.16.55
Xorg 1.12.4

current
glibc 2.28
kernel 5.10.217
Xorg 1.20.14

It all looked good until I tried to boot to the flash drive.
Got a kernel panic.
Not syncing: VFS: Unable to mount root far on unknown-block(0,0)

Hi maybl8,

For usb need rootdelay option, without infact i have same issue

Got a kernel panic.
Not syncing: VFS: Unable to mount root far on unknown-block(0,0)

On boot edit "SliTaz GNU/Linux" entry to add rootdelay=10.

To be permanent, edit /etc/default/grub

uncomment #GRUB_CMDLINE_LINUX_DEFAULT="" and edit as :

GRUB_CMDLINE_LINUX_DEFAULT="rootdelay=10"

Before rebuild config, ensure /dev/sda1 is mounted (infact no fstab entry)
mount /dev/sdX1 /boot/efi

Rebuild config
grub-mkconfig -o /boot/efi/EFI/grub/grub.cfg

Edit /etc/fstab to ensure /boot/efi is mounted at boot :)

add this entry at end
/dev/sdX1 /boot/efi vfat defaults 0 2

I am proud to announce that after all of these posts we have finally achieved what I was wanting to achieve.
I have a working slitaz system mounted on a usb flash drive that I can modify and save the changes to the flash drive on my efi laptop with a GRUB menu.

Quite a few steps installed which I am going to try to summarize in a note file of some kind.
Also I am going to try to automate as much of this as possible.

Here is the overall steps ( I hope I get them in the correct order) all details will not be listed.

1, Download a current iso and burn that to a flash drive.
2. Boot to the flash drive.
Change language to US.
Change screen resolution if needed.
3. Depending on what media you want to install to ssd drive, hard drive or flash drive.
Create 2 partitions on the drive (one for efi/boot one for root
4. Create an install script with the variables needed for your particular setup.
5. After you get a successful root install then you can install GRUB
6. Next is to install the files needed for the boot loader
7. Now you can install GRUB files a chroot is required for this step.
8. You should now be able to boot to the new slitaz install.

After booting in you might have to change screen resolution and install ucode to get wireless working depending on your hardware.

That is pretty high level instruction.
Exact commands needed for above instructions can be found in previous posts on this thread.

Thanks to the slitaz team for taking the time to get this accomplished.
I hope to work further with the team to make the install easier but if I can do it anyone should be able to to this.

Thanks again
Dan
