Appendix A Installation Troubleshooting
Types of Errors
Inst reports three types of errors: Fatal, Error, and Warning. They are
described in this section.
Fatal
A fatal message occurs if Inst encounters a severe, unrecoverable error. An
example of a fatal error is:
FATAL: mmap of /dev/zero for 4000 pages failed
Inst exits immediately after encountering a fatal error. Fatal errors can be
caused by hardware failures or lack of sufficient operating system resources,
such as swap space. If a fatal error occurs, you might need to load the
miniroot and take corrective action by modifying system configuration files.
Error
An error message indicates that a command or other function was unable to
complete successfully. For example:
Inst> from /irix5.3
ERROR : The distribution /irix5.3 does not exist.
You may want to retry the operation after taking corrective measures.
Warning
A warning indicates an unusual condition that Inst is prepared to handle, but
which may cause problems later during the installation. For example:
% inst
WARNING : Starting up as Read Only (no installs or removals)
Inst will start, but in read-only mode.
