# A bash script to download and run a debian on mips, ppc, arm, x86 or x64 using qemu. |
|
# Copyright 2020 Jason Pepas |

# Released under the MIT license, see https://opensource.org/license/mit |

|
|
# Usage: |
|
# $ qemu.sh mips |
|
# $ qemu.sh ppc |
|
# $ qemu.sh arm |
|
# $ qemu.sh x86 |
|
# $ qemu.sh x64 |
|
|
|
# Note: any additional arguments are passed to qemu itself, e.g.: |
|
# $ qemu.sh mips -vnc |
|
|
|
# The root password is 'root', the account 'user' has password 'user'. |
|
# SSH via 'ssh -p 2222 user@localhost'. |
|
|
|
# Tips: |
|
# - Debian packages for wheezy have been moved to archive.debian.org, try: |
|
# 'echo deb http://archive.debian.org/debian wheezy main > /etc/apt/sources.list'. |
|
# - The smart bash-completion package is slow under qemu, try: |
|
# 'apt-get remove bash-completion'. |
