- Only set the fields in the ulog_utmpx structure that are valid for the command in question. This means that strings like "shutdown" or "~" are not visible to the user anymore. - Rename UTXF_* to UTXI_*, indicating the indexation, instead of using the `antique' filename. If we ever get rid of utmp, it makes little sense calling it by its old name.

.Fa user
|
|
argument.
