By using UUID we solve the problem when there are multiple disks and we don't knowing how kernel enumerates them after boot. This is to handle the case when /boot is on separate partition.Ĭreate /boot/nf with contents like (check the filesystem type for alpine_dev kernel and initrd are relative to partition root):Īppend initrd=/boot/grsec.gz alpine_dev=sda2:ext3 modloop=grsec.cmg modules=loop,cramfs,sd-mod,usb-storage,ext3 quietįrom Alpine Linux 2.1 you can use the UUID of the partition that holds the apkovl and the apks directory, the current root. Make sure that /boot dir has a symlink pointing to itself. Next we make the Alpine Linux kernel bootable (requires syslinux) and use fdisk to mark the /boot partition as bootable (if not done already):ĭd if=/usr/share/syslinux/mbr.bin of=/dev/sda # on some older systems its /usr/lib/syslinux/mbr.bin

If you don't have ext3 on / or /boot, then you might be able to disable swap and reformat the swap partition as ext3 and use that.ĭownload an alpine iso and mount it for exampleĬopy the apkovl and the contents of cd-rom image to root of current installation: This guide assumes they are on sda1 (/boot) and sda2 (/) with both having ext3 filesystems. However, /boot is usually small, so you might want to put the apks on separate partition. These can reside on same partition if they fit. We need to copy over two sets of information: the boot kernel (kernel, initramdisk and boot configuration) and operating system boot data (overlay, apk packages and kernel modules). Verify the overlay with 'tar tzf' to see that it contains everything in proper places, and ensure it is in the / directory Mkdir -p etc/ssh etc/network etc/runlevels/ etc/runlevels/shutdown/ We need the new box to start networking and ssh in the beginning so we can reconnect to it after reboot. The first step is to create Alpine configuration file with basic configuration of the host. You can then open the overlay and set up networking exactly as it should be on the target box, then repackage the overlay and drop in the root of alpine_dev on the remote host.) Note: This entire section can be replaced by setting up a box from scratch, using setup-alpine and selecting 'none' for the install disk, then running 'lbu ci' to save the apkovl.
