Alpine setup scripts

This page summarizes the low-level behavior of the /sbin/setup-* scripts on the Alpine ISO (and in a normal Alpine install).

setup-alpine

This script accepts the following command-line arguments (you can run `setup-alpine -h` to see some of these entries).

-a Create overlay file: this creates a temporary directory and saves its location in ROOT; however, the script doesn't export this variable so I think this feature isn't currently functional.
-c FILE Create a new "answer file", with default choices. You can edit the file and then invoke `setup-alpine -f FILE`.
-f FILE Use an existing "answer file", which may override some or all of the interactive prompts.
-q Run in "quick mode" (not documented by `setup-alpine -h`). See below for details.

The script's behavior is to do the following, in order. Bracketed options represent extra configuration choices than can be supplied when running the auxiliary setup scripts manually, or by supplying an "answer file".

`setup-keymap` [us us]
`setup-hostname` [-n alpine-test]
`setup-interfaces` [-i < interfaces-file] LINK
`/etc/init.d/networking --quiet start &`
if none of the networking interfaces were configured using dhcp, then: `setup-dns` [-d example.com -n "8.8.8.8 [more...]"]
set the root password
if not in quick mode, then: setup-timezone [-z UTC] LINK
enable the new hostname (`/etc/init.d/hostname --quiet restart`)
add networking and urandom to the "boot" rc level, and acpid and cron to the "default" rc level, and start the boot and default rc services
extract the fully-qualified domain name and hostname from /etc/resolv.conf and `hostname`, and update /etc/hosts
`setup-apkrepos` [-r (to select a mirror randomly)]
if not in quick mode, then: `setup-sshd` [-c openssh | dropbear | none]
if not in quick mode, then: `setup-ntp` [-c chrony | openntpd | none]
if not in quick mode, then: `DEFAULT_DISK=none setup-disk -q` [-m data /dev/sda] LINK
if not in quick mode, and the selected disk mode was "data" instead of "sys", then: `setup-lbu` [/media/sdb1]
if not in quick mode, and the selected disk mode was "data" instead of "sys", then: `setup-apkcache` [/media/sdb1/cache]

setup-interfaces

An interfaces file has the format of /etc/network/interfaces, such as:

   auto lo
   iface lo inet loopback

   auto eth0
   iface eth0 inet dhcp
       hostname alpine-test

setup-timezone

Can pre-select the timezone using either of these switches:

-z <subfolder of /usr/share/zoneinfo>
-p <POSIX TZ format>
