chroot_lvm_snapshot::chroot_lvm_snapshot | ( | ) | [protected] |
The constructor.
chroot_lvm_snapshot::~chroot_lvm_snapshot | ( | ) | [virtual] |
The destructor.
sbuild::chroot::ptr chroot_lvm_snapshot::clone | ( | ) | const [virtual] |
Copy the chroot.
This is a virtual copy constructor.
Reimplemented from sbuild::chroot_block_device.
sbuild::chroot::ptr chroot_lvm_snapshot::clone_source | ( | ) | const [virtual] |
std::string const & chroot_lvm_snapshot::get_chroot_type | ( | ) | const [virtual] |
Get the type of the chroot.
Reimplemented from sbuild::chroot_block_device.
void chroot_lvm_snapshot::get_details | ( | format_detail & | detail | ) | const [protected, virtual] |
Get detailed information about the chroot for output.
detail | the details to output to. |
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.
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.
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.
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.
std::string const & chroot_lvm_snapshot::get_snapshot_options | ( | ) | const |
Get the logical volume snapshot options.
These are used by lvcreate.
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.
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.
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.
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.
env | the environment to set. |
Reimplemented from sbuild::chroot_block_device.
void chroot_lvm_snapshot::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). |
Reimplemented from sbuild::chroot_block_device.
friend class chroot [friend] |
Reimplemented from sbuild::chroot_block_device.
std::string sbuild::chroot_lvm_snapshot::snapshot_device [private] |
LVM snapshot device name for lvcreate.
std::string sbuild::chroot_lvm_snapshot::snapshot_options [private] |
LVM snapshot options for lvcreate.
