|
||||
|
||||
B<mmdebstrap-autopkgtest-build-qemu> is a mostly compatible drop-in replacement
|
||||
for B<autopkgtest-build-qemu>(1) with two main differences: Firstly, it uses
|
||||
B<mmdebstrap>(1) instead of B<vmdb2>(1) and thus is able to create QEMU disk
|
||||
images without requiring superuser privileges. Secondly, it uses
|
||||
B<systemd-boot>(7) and thus only supports booting via EFI.

||||
Set the architecture for the virtual machine image, specified as a B<dpkg>(1)
|
||||
architecture. If omitted, the host architecture is assumed.
|
||||
|
||||
B<--arch>=I<ARCH> is an alias for this option.
|
||||
|
||||
=item B<--script>=I<SCRIPT>
|
||||
|
||||
Specifies a user script that will be called with the root filesystem of the
|
||||
image as its first parameter. This script can them make any necesssary
|
||||
modifications to the root filesystem.
|
||||
|
||||
The script must be a POSIX shell script, and should not depend on bash-specific
|
||||
features. This script will be executed inside a B<chroot>(1) call in the
|
||||
virtual machine root filesystem.
|
||||
|
||||
=item B<--size>=I<SIZE>
|
||||
|
||||
Specifies the image size for the virtual machine, defaulting to 25G.
|
||||
|
||||
=item B<--apt-proxy>=I<PROXY>
|
||||
|
||||
Specify an apt proxy to use in the virtual machine. By default, if you have
|
||||
an apt proxy configured on the host, the virtual machine will automatically use
|
||||
this, otherwise there is no default.
|
||||
|
||||
=item B<--boot>=B<efi>, B<--efi>
|
||||
|
||||
Select the way the generated image will expect to be booted. Unless you
|
||||
explicitly select --boot=efi, operation will fail.
|
||||
|
||||
=item B<--keyring>=I<KEYRING>
|
||||
|
||||
Passes an additional B<--keyring> parameter to B<mmdebstrap>.
