Detailed Description

A chroot stored on an LVM logical volume (LV).

A snapshot LV will be created and mounted on demand.

Member Function Documentation

sbuild::chroot::ptr chroot_lvm_snapshot::clone (   )  const [virtual]

Copy the chroot. This is a virtual copy constructor. Returns: a shared_ptr to the new copy of the chroot. Reimplemented from sbuild::chroot_block_device.

sbuild::chroot::ptr chroot_lvm_snapshot::clone_source (   )  const [virtual]

Implements sbuild::chroot_source.

std::string const & chroot_lvm_snapshot::get_chroot_type (   )  const [virtual]

Get the type of the chroot. Returns: the chroot type. Reimplemented from sbuild::chroot_block_device.

void chroot_lvm_snapshot::get_keyfile (  keyfile &  keyfile  )  const [protected, virtual]

Copy the chroot properties into a keyfile. The keyfile group with the name of the chroot will be set; if it already exists, it will be removed before setting it. Parameters: keyfile  the keyfile to use. Reimplemented from sbuild::chroot_block_device.

std::string const & chroot_lvm_snapshot::get_mount_device (   )  const [virtual]

Get the mount device of the chroot. Returns: the device. Reimplemented from sbuild::chroot_block_device.

sbuild::chroot::session_flags chroot_lvm_snapshot::get_session_flags (   )  const [virtual]

Get the session flags of the chroot. These determine how the Session controlling the chroot will operate. Returns: the session flags. Reimplemented from sbuild::chroot_block_device.

std::string const & chroot_lvm_snapshot::get_snapshot_device (   )  const

Get the logical volume snapshot device name. This is used by lvcreate. Returns: the device name.

std::string const & chroot_lvm_snapshot::get_snapshot_options (   )  const

Get the logical volume snapshot options. These are used by lvcreate. Returns: the options.

void chroot_lvm_snapshot::print_details (  std::ostream &  stream  )  const [protected, virtual]

Print detailed information about the chroot to a stream. The information is printed in plain text with one line per property. Parameters: stream  the stream to output to. Reimplemented from sbuild::chroot_block_device.

void chroot_lvm_snapshot::set_keyfile (  keyfile const &  keyfile  )  [protected, virtual]

Set the chroot properties from a keyfile. The chroot name must have previously been set, so that the correct keyfile group may be determined. Parameters: keyfile  the keyfile to get the properties from. Reimplemented from sbuild::chroot_block_device.

void chroot_lvm_snapshot::set_snapshot_device (  std::string const &  snapshot_device  )

Set the logical volume snapshot device name. This is used by lvcreate. Parameters: snapshot_device  the device name.

void chroot_lvm_snapshot::set_snapshot_options (  std::string const &  snapshot_options  )

Set the logical volume snapshot options. These are used by lvcreate. Parameters: snapshot_options  the options.

void chroot_lvm_snapshot::setup_env (  environment &  env  )  [virtual]

Set environment. Set the environment that the setup scripts will see during execution. Parameters: env  the environment to set. Reimplemented from sbuild::chroot_block_device.

void chroot_lvm_snapshot::setup_lock (  setup_type  type, bool  lock )  [virtual]

Reimplemented from sbuild::chroot_block_device.
