10.2.23 The Transactions Table
Changes to the state of the machine are made through a request entered in the
transactions table shown in Table 10.31. This table records who made each change,
when it was made and whether or not the operation was successful.
The Transaction Log Manager, tlogmgr (see Section 4.6), actions requests in the
transactions table, running commands on the user’s behalf (in practice, the user here
is a system administrator). This mechanism provides an audit trail, and sequential
ordering of changes in state.
