protectedvirtual |
Set up a newly-cloned session chroot.
parent | the parent of the cloned chroot. |
session_id | the identifier (session_id) for the new session. |

protectedvirtual |
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. |

|
virtual |
Get the name of the chroot facet.
Implements sbuild::chroot::facet::facet.
|
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.

protectedvirtual |
Get a list of the keys used during keyfile parsing.
Reimplemented from sbuild::chroot::facet::facet.
|
protectedvirtual |
Set containing chroot.
The copy parameter is used to inform the facet if it is new or a copy; this is intended to allow additional facets to only be added if the facet is new, for example, to avoid re-adding removed facets when copying a chroot.
chroot | the chroot containing this facet. |
copy | true if the facet has been copied, or false if this is a new instance. |

|
protectedvirtual |
Set the chroot properties from a keyfile.
The chroot name must have previously been set, so that the correct keyfile group may be determined.
