void sbuild::chroot::setup_env ( environment env  )  const

Set environment.

Set the environment that the setup scripts will see during execution.

Parameters:
env the environment to set.

void sbuild::chroot::setup_env ( chroot const &  chroot,
environment env 
) const [pure virtual]
virtual void sbuild::chroot::setup_lock ( setup_type  type,
bool  lock,
int  status 
) [protected, pure 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.

Parameters:
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).

Implemented in sbuild::chroot_block_device, sbuild::chroot_btrfs_snapshot, sbuild::chroot_custom, sbuild::chroot_directory, sbuild::chroot_file, sbuild::chroot_loopback, sbuild::chroot_lvm_snapshot, and sbuild::chroot_plain.
