Salix-Live-14.2 64bit Update Kernel Question

I made an update with persistent and it included the kernel-4.4.28.
How do get to boot that this kernel is used? The booting still goes into kernel-4.4.19.
I can see in system that the new kernel had been downloaded.

Hi Atip,
Just update your grub config and it will pick it up
Regards Zeb...

I don't think that will work, because the kernel needs to be in /boot, but the persistent files are only "overlayed" on top of the files in the image after boot.

You can upgrade the system using persistent but never upgrade the kernel in live editions. It will not work.

To upgrade the kernel additional work is needed.
While on live environment booting from usb with persistent.
Copy the code bellow and save it to a file named e.g. make_new_init+kernel_pack.sh
Code: Select all
sudo slapt-get -i --reinstall kernel-huge kernel-modules
sudo rm -rf /tmp/work
mkdir -p /tmp/work/new_kernel
cd /tmp/work
sudo spkg -i --root=/tmp/work/new_kernel /var/slapt-get/patches/packages/linux-4.4.38/kernel-huge-4.4.38-x86_64-1.txz
sudo spkg -i --root=/tmp/work/new_kernel /var/slapt-get/patches/packages/linux-4.4.38/kernel-modules-4.4.38-x86_64-1.txz
sudo mksquashfs new_kernel 05-kernel.slm -comp xz -b 1M
sudo mkinitrd -c -o /tmp/initrd.gz -s /tmp/initrd-tree -k 4.4.38 -m "squashfs:overlay:loop:xhci-pci:ohci-pci:ehci-pci:xhci-hcd:uhci-hcd:ehci-hcd:usb-storage:hid:usbhid:i2c-hid:hid-generic:hid-cherry:hid-logitech:hid-logitech-dj:hid-logitech-hidpp:hid-lenovo:hid-microsoft:hid_multitouch:ext3:ext4:isofs:nls_cp437:nls_iso8859-1"
sudo rm -f /tmp/initrd-tree/{initrd-name,keymap,luksdev,resumedev,rootfs,rootdev,wait-for-root}
sudo cp /usr/share/slackware-live/{init,keymaps} /tmp/initrd-tree/
sudo chmod +x /tmp/initrd-tree/init
sudo cp /usr/sbin/build-slackware-live.sh /tmp/initrd-tree/
(
cd /tmp/initrd-tree
sudo su
find . | cpio -o -H newc 2>/dev/null | gzip -9c > /tmp/work/initrd.gz
)
cd /tmp/work
Run the script
To return to user one type
Now copy the following files somewhere on hard disk or in another usb. You will need them to copy to LIVE usb later.
Create a folder
Code: Select all
cd ~/
rm -rf ~/work_files
mkdir work_files
cp /tmp/work/initrd.gz work_files
cp /tmp/work/05-kernel.slm work_files
cp /tmp/work/new_kernel/boot/vmlinuz work_files
cp -R ~/work_files somewhere-to-hard-disk
Reboot to your hard disk system
cd work_files
Copy initrd.gz to usb boot folder to replace the previous one
Copy vmlinuz to usb boot folder to replace the previous one
Copy 05-kernel.slm to usb boot/modules folder to replace the previous one
Copy initrd.gz to usb EFI/BOOT folder to replace the previous one
Copy vmlinuz to usb EFI/BOOT folder to replace the previous one
Reboot and boot with live USB
I wrote this post from salix64 live 14.2 with persistent running 4.4.38 kernel to test the above.
Code: Select all
one[~]$ uname -a
Linux salixlive 4.4.38 #2 SMP Sun Dec 11 16:18:36 CST 2016 x86_64 Intel(R) Core(TM) i3-4030U CPU @ 1.90GHz GenuineIntel GNU/Linux

Thanks! Had no Internet connection for 3 months.
Monopol company refuses to fix problem.
Now hooked-up to neighbor via wifi-repeater. Works great.
Will work on it and report.
