I have got a tar file in root of alpine ISO. During the installation of Alpine i want to extract the folder to /user/sbin. Where should i add the tar command to extract the tar file ? |

Update for Alpine Linux 3.9, adapted and tested on Kimsufi (installed from NetBoot: rescue): |

Boot up the machine in rescue boot mode and run the script. You have to correct the variables beforehand. |

I got a problem after updating my Alpine and rebooting the machine. It seems my networks config just isn't compatible with the Kimsufi network anymore. Any one got the same problems ? |

Hey Demian,
this is a great peace of work, that helped me a lot getting alpine running. But as i am a complete alpine beginner (just converted from debian) i've got some misunderstandings according to this script. Maybe you can get a bit into details for some lines:
5 PATH=/bin:/sbin:/usr/bin:/usr/sbinseems to be unused right?6 KEYMAP="us us"unused?11 FEATURES="ata base ide scsi usb virtio $ROOT_FS"I have added "raid" here to get my system booting. What exactly is that? Kernel modules? It has something to do with the RamFS. Can you explain that a little better?12 MODULES="sd-mod,usb-storage,$ROOT_FS"Curiously, I don't have to specify any raid modules for the kernel here...44 ./sbin/apk.static --repository $REPO --update-cache --allow-untrusted --root $ROOT --initdb add alpine-base syslinux dhcpcdAt this point i added "mdadm" to be right there... or what do you think?49 cat << EOF > $ROOT/etc/update-extlinux.confSince I come from Debian Syslinux/Extlinux is totally new to me.84 rc-update -q add devfs sysinitWhere should I put mdadm? sysinit or boot?107 echo features=\""$FEATURES"\" > /etc/mkinitfs/mkinitfs.confCan you explain me the boot process step by step? After BIOS/UEFI has passed to the bootloader (syslinux)... initramfs -> then kernel from / partition? I ask because syslinux knows where to find the kernel... or does syslinux need the initramfs?It would be great if you could spent some time to give me some support and answer my questions. If you wish, I can post you my Raid-Version of your script. Its working pretty stable, although I do not understand why ;-)
Greetings
David
