5.4. - Updating spec
spec
updates are normally extracted into a
directory named after the spec version number, as in
/usr/specadm/spec4.04.01
for version 4.04.01 of the software.
The instructions above for
extracting the
distribution
and installing the files also apply to updates.
Existing
settings
and
config
files from a previous installation will not be disturbed
during an update.
Each user's state
file will also remain intact,
although it is recommended that users start
out fresh (by typing
fourc -f)
after new versions are installed to
incorporate improvements to the standard macros in their state files.
Occasionally, new versions will not be compatible with
previous state files, and
spec
will automatically throw out the old state files, print a message and
start fresh anyway.
Use the
tidy_spec
utility to clean out old state files to free up disk space, especially
if the old state files are obsolete with the newer version of spec.
Update notes that accompany each new distribution indicate whether
new versions of any drivers need to be installed.
Also, the help file
changes
will contain summaries of the significant bug fixes and
improvements to spec
included in the update.
