34 # Usage instructions. Options not listed:
35 # --debug -- don't filter output from utilities
36 # --no-stats -- don't show progress statistics while fetching files
39 usage: `basename $0` [options] command ... [path]
42 -b basedir -- Operate on a system mounted at basedir
44 -d workdir -- Store working files in workdir
45 (default: /var/db/freebsd-update/)
46 -f conffile -- Read configuration options from conffile
47 (default: /etc/freebsd-update.conf)
48 -F -- Force a fetch operation to proceed
49 -k KEY -- Trust an RSA key with SHA256 hash of KEY
50 -r release -- Target for upgrade (e.g., 11.1-RELEASE)
51 -s server -- Server from which to fetch updates
52 (default: update.FreeBSD.org)
53 -t address -- Mail output of cron command, if any, to address
55 --not-running-from-cron
56 -- Run without a tty, for use by automated tools
57 --currently-running release
58 -- Update as if currently running this release
60 fetch -- Fetch updates from server
61 cron -- Sleep rand(3600) seconds, fetch updates, and send an
62 email if updates were found
63 upgrade -- Fetch upgrades to FreeBSD version specified via -r option
64 install -- Install downloaded updates or upgrades
65 rollback -- Uninstall most recently installed updates
66 IDS -- Compare the system against an index of "known good" files.
71 #### Configuration processing functions
74 # Configuration options are set in the following order of priority:
75 # 1. Command line options
76 # 2. Configuration file options
78 # In addition, certain options (e.g., IgnorePaths) can be specified multiple
79 # times and (as long as these are all in the same place, e.g., inside the
80 # configuration file) they will accumulate. Finally, because the path to the
81 # configuration file can be specified at the command line, the entire command
82 # line must be processed before we start reading the configuration file.
84 # Sound like a mess? It is. Here's how we handle this:
85 # 1. Initialize CONFFILE and all the options to "".
86 # 2. Process the command line. Throw an error if a non-accumulating option
88 # 3. If CONFFILE is "", set CONFFILE to /etc/freebsd-update.conf .
89 # 4. For all the configuration options X, set X_saved to X.
90 # 5. Initialize all the options to "".
91 # 6. Read CONFFILE line by line, parsing options.
92 # 7. For each configuration option X, set X to X_saved iff X_saved is not "".
93 # 8. Repeat steps 4-7, except setting options to their default values at (6).
