A chroot stored in a file for loopback mounting.
The file will be mounted on demand.

void chroot_loopback::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.

std::string chroot_loopback::get_path | ( | ) | const [virtual] |
Get the path to the chroot.
This is the absolute path to the root of the chroot, and is typically the same as the mount location and location concatenated together, but is overridden by the chroot type if required.
Implements sbuild::chroot.
References sbuild::chroot::get_mount_location().
sbuild::chroot::session_flags chroot_loopback::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. |
Implements sbuild::chroot.

void chroot_loopback::set_file | ( | std::string const & | file | ) |

void chroot_loopback::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. |

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. |

void chroot_loopback::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). |
