+# Alpine Dropbear Initramfs
+This script took a huge references from:
+
+* [https://github.com/Deeplerg/fork-alpine-initramfs-dropbear](https://github.com/Deeplerg/fork-alpine-initramfs-dropbear)
+
+* [https://github.com/mk-f/alpine-initramfs-dropbear](https://github.com/mk-f/alpine-initramfs-dropbear)
+
+* [https://gitlab.alpinelinux.org/alpine/mkinitfs/-/blob/master/initramfs-init.in](https://gitlab.alpinelinux.org/alpine/mkinitfs/-/blob/master/initramfs-init.in)
+
+This script is modified from [alpine/mkinitfs - initramfs-init.in](https://gitlab.alpinelinux.org/alpine/mkinitfs/-/blob/master/initramfs-init.in)
+
+significant changes:
+
+* Add dropbear
+
+* Add dropbear session timer, this make typical decryption still works even if dropbear/network is broken
+
+Please install `dropbear` before continuing
+
+1. copy `dropbear/unlock_disk` to `/etc/dropbear/unlock_disk`
+2. copy `authorized_keys` to `/etc/dropbear/authorized_keys`
+3. copy `features.d` to /`etc/mkinitfs/features.d`
+
+Note: if you're using Deeplerg/mk-f scripts before don't forget to change `unlock_disk` as i modified that one too.
+
+### /etc/mkinitfs.conf
+`features="ata base ide scsi usb virtio ext4 cryptsetup keymap dropbear network"`
+* features+= `dropbear` `network`
+
+### /etc/update-extlinux.conf
+`modules=sd-mod,usb-storage,ext4,ata_piix,virtio_net,e1000e,virtio_pci`
+* if network is not working (/sys/class/net/*/address not found etc.) try adding `e1000e` or `virtio_net` `virtio_pci`
+
+`default_kernel_opts="cryptroot=UUID=xxx cryptdm=root quiet rootfstype=ext4 dropbear=<dropbear_port> ip=<ip>>"`
+* ip= can be both static and dhcp(if supported) `ip=<ip>::<gw>:<mask>::<interface>` `ip=dhcp`
+
+
+`update-extlinux`
+
+`mkinitfs -i path/to/initramfs-dropbear <Kernel Version(from /lib/modules) incase in emergency CD>`
