| ***logging** - things/events/changes should be suitably and appropriately logged, and in appropriate location(s). This is not only generally considered "best practice", but it is particularly important when multiple persons are involved (e.g. with systems administration) on a host - such as the case with this host. There is not only the logging done by software itself (and via its configuration), but also appropriate (mostly) human generated log entries and/or details. Exactly how, where, and what, should be logged, may "evolve" over time (and with discussion and seeing what does/doesn't work so well for different stuff). At present, there are at least these, and their apparent current usage: | ***logging** - things/events/changes should be suitably and appropriately logged, and in appropriate location(s).

| ***file:/home/admin/log** - (up to) rather detailed chronological logging potentially including anything that might be worthy of noting/recording. It's also readable by anyone via the Internet (accessible as [[http://www.sf-lug.com/log.txt]]), so only items suitable for being that openly exposed should be placed there. | ***file:/var/local/log/log** - (up to) rather detailed chronological logging potentially including anything that might be worthy of noting/recording.

| ***documenting**/**documentation** - as feasible and appropriate, things should be documented (and/or logged). This is particularly noteworthy/important given both the number of folks that do or may work on this system, and also many of the objectives of the system (e.g. learning/teaching). | ***documenting**/**documentation** - as feasible and appropriate, things should be documented (and/or logged).
