Single User Mode Questions (mac)
Hello everyone. Completely new here (so if this post is in the wrong forum point me in the right direction), and fairly new to unix. I have a macbook pro and just recently started messing around with the Single User Mode, where i can manipulate directories/files/etc using unix. I have also just recently learned how to log in as an administrator using the passwd root command and such, which i thought was an interesting hole/hack in the system security and im just curious if anyone knows any other interesting commands/hacks n such that i can mess around with? Like for instance if i wanted to be a real jerk and delete someones operating system (in my case OSX) files and ruin their computer? Not that i would do such a thing, but just curious if its possible. Or any other loopholes or even beneficial mods or anything i can do while in this single user mode?

hotswaprc

HOTSWAPRC(5)							File Formats Manual						      HOTSWAPRC(5)

NAME

       hotswaprc - configuration file for  hotswap

DESCRIPTION

       /etc/hotswaprc is the global configuration file for the hotswap utility.

       It  allows system administrators to specify arbitrary shell scripts to be run after a device is inserted, as well as before and after it is
       removed. Scripts are selected according to the model name retrieved from the device. This is particularly helpful for automatic	configura-
       tion of CD-RW drives, which require SCSI emulation and bypass normal access via the IDE subsystem.

       hotswaprc  is  implemented  as  an  Extensible Mark-up Language (XML) application.  XML documents are structured using elements of the form
       <tag-name> content <tag-name>. A Document Type Definition (DTD) describes the possible content of each element.

       Please refer to the XML specification for more information. The hotswap distribution also contains an example file,  doc/hotswaprc.example,
       which includes the DTD for the configuration file format.

ELEMENTS

       <hotswap>
	      This is the root element of the document. Each valid hotswaprc must contain exactly one <hotswap> element. The <hotswap> element may
	      contain an arbitrary number of <device> elements.

       <device>
	      The configuration file contains one <device> element for every device for which scripts are defined. The <device>  element  is  com-
	      posed of the following elements in this order: <name>, <post-insert>, <pre-remove>, <post-remove>. All but <name> are optional.

       <name> The content of this element is the model identification string of the IDE device the current <device> element refers to.

       <post-insert>
	      Contains the shell script that is to be executed after the device has been inserted and registered with the kernel.

       <pre-remove>
	      Contains the shell script that is to be run before hotswap attempts to unregister the device.

       <post-remove>
	      Contains the shell script that is to be run after the device had been unregistered.
