Howto: Install Alpine Linux 3.3 on VirtualBox OSX

• Latest Standard ISO version x86_64 is recommended (http://alpinelinux.org/downloads/)
• Create new VM ("Linux 2.6 / 3.x / 4.x (64-bit)")
• 1 CPU w/ 512BM RAM and 1 GB default (VDI) disk is more than sufficient
• Default networking (NAT)
• Boot and add Alpine ISO as attached virtual install media
• Default root password is blank (though note - ssh PermitRootLogin defaults to disallow blank passwords and: prohibit-password; switch to yes for Host ssh)
• Run setup-alpine
• Defaults are fine, but you do want "sys" disk setup to sda, y to confirm

# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.
#
# Once you're done here, go to
# http://www.gnu.org/software/make/manual/make.html
# to learn SOOOO much more.

# Use list view in all Finder windows by default
# Four-letter codes for the other view modes: `icnv`, `clmv`, `glyv`

defaults write com.apple.finder FXPreferredViewStyle -string "Nlsv"

# Remove other views, which Finder remembered because of the .DS_Store files:

find ~ -name ".DS_Store" -delete 2>/dev/null
defaults write com.apple.desktopservices DSDontWriteNetworkStores true

If completely wiping & reinstalling a Postgres DB, when running initdb like:

service postgresql-9.2 initdb -E 'UTF8' --pgdata="/foo/bar/"

you can encounter this service error:

Data directory is not empty! [FAILED]

To fix it (and this is the nuclear option -- all db data is wiped!)

sudo vi /etc/pam.d/sudo

Add to the end BEGINNING of the file:
