Just to get it clear: I did not suggest it to be enabled without user intervention. All I had in mind was to move this particular parameter to rc.conf (or similar) instead of the sysctl. Sorry if this did not came through, but this is the $SUBJECT of this thread so I thought it was obvious. The problem with sysctls is only one: They tend to be badly documented. After all, grepping through the source is not always an option and this may or may not have to do with the admin's level of experience. It may also be space constraints, not having the source, etc. > > > For example the docs up to this day ignore the tool 'mergemaster' > > although it has become a standard util from a third-party app. > > Did you write the docs and sent them to the FreeBSD docs folks? > That's what send-pr is for. _Someone_ has to write the docs, > otherwise they don't exist. Docs don't fall from the sky. I could not agree more. I did not write this to start a rant against the -doc people. I am on that mailing list as well and know how hard they are working. I wish I had more time on my hands so that I could submit some docs... but this is examination time for us at University and since my major is not in the least computer-related, this is quite a distraction. Maybe a couple of weeks later... until then, I will try to polish my SGML/DocBook skills and improve my English, both of which are critical now:-) > > > BTW I see another similar case: why do you need a sysctl in order to allow > > ordinary users to mount/umount removable media? > > Because it would be a security hole if it was enabled by > default.

I bet any vendor would not know that automounting CDs was actually possible using BSD so they say: see, Linux is more developed and more suited to the mass market.

Someone already submitted the number, unless I am mistaken. Regards and have a nice evening, everybody!
