Apply a rollback.
@param rollbackSpec: Rollback specififier. This is either a number (in
which case it refers to the absolute position in the rollback stack, with
0 being the oldest rollback) or a string like C{r.128}, as listed by
C{conary rblist}.
@type rollbackSpec: string
@param replaceFiles:
@type replaceFiles: bool
@param callback: Callback for communicating information back to the
invoker of this method.
@type callback: L{callbacks.UpdateCallback}
@param tagScript: A tag script.
@type tagScript: path
@param justDatabase: Change only the database, do not revert the
filesystem.
@type justDatabase: bool
@param noScripts: Do not run trove scripts, including rpm scripts.
@type noScripts: bool
@param transactionCounter: The Conary database contains a counter that
gets incremented with every change. This argument is the counter's value
at the time the rollback was computed from the specifier. It is used to
ensure that no uninteded rollbacks are performed, if a concurrent update
happens between the moment of reading the database state and the moment
of performing the rollback.
@type transactionCounter: int
@param abortOnError: Abort the rollback if any pre-rollback scripts
fail. Normally, the rollback continues even if there are pre-rollback
script failures.
@type abortOnError: bool
@param capsuleChangesets: List of paths to changesets. Any capsules
included in those changesets are made available to the rollback
in case they are needed. If a directory is given, every changeset
in that directory is included (nonrecursively) while non-changeset
files are ignored.
@type capsuleChangesets: list of str
@raise UpdateError: Generic update error. Can occur if the root is not
writeable by the user running the command.
@raise RollbackError: Generic rollback error. Finer grained rollback
errors are L{RollbackDoesNotExist<database.RollbackDoesNotExist>}
(raised if the rollback specifier was invalid) and
L{RollbackOrderError<database.RollbackOrderError>}
(if the rollback was attempted not
following the rollback stack order). It can also be raised if the
database state has changed between the moment the rollback was
computed and the moment of performing the rollback. See also the
description for C{transactionCounter}.
@raise ConaryError: Generic Conary error. Raised if the user running the
command does not have permissions to access the rollback directory, or the
directory is missing.
