# Old Arch Install Notes:

###################################################
# These notes are for several different installs over years.
# Usually commenting out the old differences from the current
# machine. So don't copy blindly. I don't clean it up as a
# reminder of the olden.

# Some things have changed since I last tried Arch. Seems like
# less configuration is going in /etc/rc.conf. Also the
# /arch/setup script seems to be chased off.

# ifconfig not around: (ip addr show)
# http://www.archlinux.org/news/deprecation-of-net-tools/

# Installing Arch
# https://wiki.archlinux.org/index.php/Beginners'_Guide
# https://wiki.archlinux.org/index.php/installation_guide
# You should probably head there if you are having to read this.
# These are just my notes for installing in a virtualbox.

# Extra info on archGuest in vbox:
# https://wiki.archlinux.org/index.php/Arch_Linux_VirtualBox_Guest

# Boot from cd. Should auto login as root, if not login as
# root with no password.

rmmod pcspkr
# Turn off beeps (during install)

timedatectl set-ntp true
# Sync to ntp time
# Make sure you are online before running this

timedatectl status
# Check status of timedatectl

#- Invalid partition table! Dell E6230 --
#----------------------------------------
# After going through install got:
# Invalid partition table!
# I had a problem like this a long time ago and ended up using
# MBR instead of GPT and it worked, but I think this one is
# related to the BIOS possibly.
# Booting from install media and running:
parted /dev/sda
disk_toggle pmbr_boot
quit
reboot
# Fixed the problem. Seems bios wanted a boot flag set.

#-----------------------------
#- Extra signatures on disk --
#-----------------------------
# When trying to mount /dev/sda1 with: 
mount /dev/sda1 /mnt
# Was given an error/warning about extra signatures.
# (This used to be a freebsd drive with zfs.)
# It advised I use wipefs:
wipefs /dev/sda1
# Shows I have the ext4 that was just created, but also has zfs_member.
# Removed it with:
wipefs -o 0x4a85bff000
# Run wipefs again and see there is another one. Seems to only
# get rid of the first zfs_member it runs into.
wipefs /dev/sda1
# Tried to use:
wipefs -a -t zfs_member /dev/sda1
# To get rid of all zfs_member, but could not figure out correct syntax.
# Run it a couple times on offsets and see if only a couple.
wipefs -o 0x4a85bfe000
wipefs -o 0x4a85bfd000
wipefs -o 0x4a85bff000
# Nope could be doing this all day.
# Grab the offset with awk:
wipefs /dev/sda1 | grep zfs | awk '{print $1}'
# Chunk offsets with a for loop: (not sure how many, but can try 200 first)
