h1. Managing Alpine Linux

{{toc}}

h2. Create a UEFI bootable usb stick

* Download the alpine iso

* Create one fresh new partition on the USB stick - NEEDS TO BE GPT

** partition type must be EFI (ef00)

* Format the partition with mkfs.vfat

* mount the ISO (mount -o loop /path/to/iso /somewhere)

* mount the USB stick (mount /dev/sdX1 /somewhere_else)

** copy files from the alpine ISO: @cd /somewhere; tar c . | ( cd /somewhere_else; tar xv ; sync)@

* umount the usb stick

* umount the ISO

You can now use the USB stick for UEFI booting.

h2. Installing in IPv6 only networks

* Select DHCP

* After it acquires an IP address stop and change to a different console

* Add valid DNS servers to */etc/resolv.conf*

** In our case: for instance @nameserver 2a0a:e5c0:2:a::a@

* Test pinging: @ping ungleich.ch@

h2. Installing with encrypted root filesystem

* apk add cryptsetup

* abort setup-alpine

* mounting manually the crypted device

* switching to setup-disk /mnt

* bind mounting the dev/sys/proc/efivars into /mnt

* modifying /etc/mkinitfs/mkinitfs.conf to include cryptsetup AND nvme!

* running mkinitfs

* install grub-efi

* modify /etc/default/grub

* apk add efibootmgr in the chroot

* run grub-install --efi-directory=/boot

* apk add dhcpcd

* grub-mkconfig > /boot/grub/grub.cfg

* setup root password in chroot

* post reboot: switch repos to edge (required for variety of packages)
