A chroot stored on an unmounted block device.
The device will be mounted on demand.
sbuild::chroot::ptr chroot_block_device::clone | ( | ) | const [virtual] |

void chroot_block_device::get_details | ( | chroot const & | chroot, |

Reimplemented from sbuild::chroot_block_device_base.
void chroot_block_device::get_keyfile | ( | chroot const & | chroot, |
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.
chroot | the chroot to use. |
keyfile | the keyfile to use. |
Reimplemented from sbuild::chroot_block_device_base.
sbuild::chroot::session_flags chroot_block_device::get_session_flags | ( | chroot const & | chroot | ) | const [virtual] |
Get the session flags of the chroot.
These determine how the Session controlling the chroot will operate.
chroot | the chroot to use. |
Reimplemented from sbuild::chroot_block_device_base.

void chroot_block_device::set_keyfile | ( | chroot & | chroot, |
keyfile const & | keyfile, | ||
string_list & | used_keys | ||
) | [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.
chroot | the chroot to use. |
keyfile | the keyfile to get the properties from. |
used_keys | a list of the keys used will be set. |
Reimplemented from sbuild::chroot_block_device_base.
void chroot_block_device::setup_env | ( | chroot const & | chroot, |
environment & | env | ||
) | const [virtual] |
Set environment.
Set the environment that the setup scripts will see during execution.
chroot | the chroot to use. |
env | the environment to set. |
Reimplemented from sbuild::chroot_block_device_base.
void chroot_block_device::setup_lock | ( | chroot::setup_type | type, |
bool | lock, | ||
int | status | ||
) | [protected, virtual] |
Unlock a chroot during setup.
The locking technique (if any) may vary depending upon the chroot type and setup stage. For example, during creation of an LVM snapshot a block device might require locking, but afterwards this will change to the new block device.
An error will be thrown on failure.
type | the type of setup being performed |
lock | true to lock, false to unlock |
status | the exit status of the setup commands (0 for success, nonzero for failure). |
