# Reasons why this is only working on amd64 and i386
|
|
#
|
|
# - /usr/share/autopkgtest/setup-commands/setup-testbed only seems to be
|
|
# written for those architectures
|
|
# - extlinux is limited to amd64 and i386
|
|
# - autopkgtest is unable to reach the testbed when we boot with grub
|
|
#
|
|
# To make this work with more architectures we need to:
|
|
#
|
|
# - adjust GRUB_CMDLINE_LINUX_DEFAULT for architectures other than amd64 and
|
|
# i386 in /usr/share/autopkgtest/setup-commands/setup-testbed
|
|
# - make this work with grub2 instead of extlinux
