void chroot_block_device::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.

void chroot_block_device::set_device | ( | std::string const & | device | ) |
Set the block device of the chroot.
This is the "source" device. It may be the case that the real device is different (for example, an LVM snapshot PV), but by default will be the device to mount.
device | the device. |

void chroot_block_device::set_keyfile | ( | 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.
keyfile | the keyfile to get the properties from. | |
used_keys | a list of the keys used will be set. |

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). |
