29: ## Obvious flaws of this program:
30: ## Dieing on every error may be a little extreme. On the other hand,
31: ## how the heck am I supposed to know what absurd things the user
32: ## has done with their system before inflicting LON-CAPA on it?
33: ## The links to /etc/init.d for httpd and mysqld do not seem to work :(
34: ## The user is never informed of the log file (/tmp/loncapa_install.log).
35: ## It does not test the system at the end. Again, there are limits to
36: ## what nonsense we can put up with. Of course, we will have to
37: ## explain that to people at some point...
38: ## There is probably an overuse of elipses (...) in the comments.
39: ## It might be nice to check that all the files we need are here.
40: ## Appletalk is installed but does not work and gives errors on
41: ## boot up. I have not been able to find a clean way to get the
42: ## appletalk support working but the powers that be insist on it.
