gboolean ostree_sysroot_upgrader_check_timestamps (OstreeRepo *repo,const char *from_rev,const char *to_rev,GError **error);
Check that the timestamp on to_rev
 is equal to or newer than
from_rev
.  This protects systems against man-in-the-middle
attackers which provide a client with an older commit.
gboolean ostree_sysroot_upgrader_pull (OstreeSysrootUpgrader *self,OstreeRepoPullFlags flags,OstreeSysrootUpgraderPullFlags upgrader_flags,OstreeAsyncProgress *progress,gboolean *out_changed,GCancellable *cancellable,GError **error);
Perform a pull from the origin.  First check if the ref has
changed, if so download the linked objects, and store the updated
ref locally.  Then out_changed
 will be TRUE.
If the origin remote is unchanged, out_changed
 will be set to
FALSE.

Like ostree_sysroot_upgrader_pull(), but allows retrieving just a
subpath of the tree.  This can be used to download metadata files
from inside the tree such as package databases.
gboolean ostree_sysroot_upgrader_deploy (OstreeSysrootUpgrader *self,GCancellable *cancellable,GError **error);
Write the new deployment to disk, perform a configuration merge with /etc, and update the bootloader configuration.
