Can't open file: reason here
newaliases: cannot open file: reason here
Here, the error might be caused by the file simply not existing (as would be the case if it was
NFS-mounted on a down host) or an I/O error (as would be the case if it was a bad disk):
warning: cannot lock file: reason here
Failure to lock can be caused by system errors or by the file being read-only. Note that
maintaining an aliases file under revision control can cause a read-only copy to exist,
resulting in the following error:
Can't create database for file: reason here
Cannot create database for alias file file
This error indicates that the output file (the dbm(3) or db(3) file) could not be created or
written.

message with a syslog(3) level of LOG_CRIT:
forward: no home

loop check described earlier:
