# FreeBSD setup script
# for Mac VirtualBox with screen magnification
# Silas S. Brown 2020-2023, public domain

# Tested on Mac OS 10.7.5, VirtualBox 4.3.4
# We install 2 Firefox profiles (one with CSS, one w/out)
# because old Mac OS X can't run latest browsers.

export User=ssb22

# Setup source:
# https://download.freebsd.org/ftp/releases/ISO-IMAGES/12.4/FreeBSD-12.4-RELEASE-amd64-bootonly.iso.xz

# Setup:
# type: FreeBSD (64-bit) (ensure to select 64-bit)
# 2G RAM (1G insufficient for Firefox on some websites)
# 16G virtual hdd (8G was doable in 12.2 but not 12.4)
# System/motherboard/enable I/O APIC
# General/Advanced shared clipboard = bidirectional
# Display: 3D acceleration = enabled
# Network/Advanced/port forwarding: host port 22022 to guest port 22 (leave IPs blank)
# Install / (Dvorak or whatever keymap) / Continue / hostname / deselect optional components / network (dhcp=y ipv6=n resolver=default) / mirror (e.g. UK2) / auto, entire disk, mbr, (if on SSD suggest delete swap and expand main partition) / root pwd / time zone / (no services, usrs) / reboot (rm disc)

# Then run:
# pkg install curl
# curl https://raw.githubusercontent.com/ssb22/bits-and-bobs/%6d%61%73%74%65%72/freebsd-setup.sh > freebsd-setup.sh && chmod +x freebsd-setup.sh && ./freebsd-setup.sh

# Work around bug copying browser text to host clipboard
# - it seems host won't take it from CLIPBOARD set by browser, but will take it from CLIPBOARD set by xclip.
# So we watch for SetSelectionOwnerNotify on CLIPBOARD,
# and then copy PRIMARY (which should be the same) to
# CLIPBOARD via xclip.
# (Our patch to xfixes-selection-notify.py causes it to
# exit only if owner is not set by 'main' i.e. the host.
# This avoids an unwanted side-effect of reacting to any
# change in clipboard on the host side also, when vbox
# copies host to guest: if both plain text and another
# format like RTF are available on the host side, we
# probably don't want the vbox to take over as owner and
# make it plain-text only.)
