NAME

       sbuild-qemu-update - sbuild-update analog for QEMU images

SYNOPSIS

       sbuild-qemu-update [-h] [--snapshot] [--arch=ARCH] [--noexec] IMAGE

DESCRIPTION

       sbuild-qemu-update  boots  a  QEMU  VM using IMAGE and then runs apt-get in it, performing
       update, dist-upgrade, clean and autoremove. It can optionally  create  a  snapshot  before
       updating.

       The architecture is auto-guessed by stripping any file suffix and then splitting the image
       name on dashes ``-'', and  finally  by  looking  for  a  Debian  architecture  name.  sid-
       amd64.img,  amd64-temporary.image  or  even  just  amd64  would all be assumed to be amd64
       images, but not amd64.rebuild-tests.img. If this guesses wrong, use the --arch option.

OPTIONS

       -h, --help
              Show this help message and exit.

       --snapshot
              Create a snapshot of the image  before  changing  it.  Useful  for  reproducibility
              purposes.

       --arch=ARCH
              Architecture to use (instead of attempting to auto-guess).

       --timeout=SECS
              Maximum  time  to  wait for command to finish with expected result. Mostly relevant
              for foreign architectures, where apt-get update can take quite  a  while.  Default:
              600s.

       --noexec
              Don't  actually  do anything. Just print the command string that would be executed,
              and then exit.

EXAMPLES

       $ sbuild-qemu-update unstable-autopkgtest-amd64.img

       This will update the image unstable-autopkgtest-amd64.img in the current directory. If  no
       such file exists there, then $IMAGEDIR/unstable-autopkgtest-amd64.img is tried.

ENVIRONMENT

       If $IMAGEDIR is unset, then ~/.cache/sbuild is used.
