[ #12040 ]

Yesterday I did this:

sudo rm -f /dev/ttyp2

Do not do this. As hfb will happily remind me - this is why I am not a sysadmin ;-)

  • I can't think of any reason why you'd want to do that. Why did you do that? :)

  • I once accidentally (duh) made all of /lib on a Solaris box non-executable, which meant basically nothing would run. Unfortunately, unlike Linux (and probably BSDs, I'd guess), Solaris doesn't seem to include any "save my ass" statically linked binary like busybox. Fun fun.
    • There's one: /sbin/sh, if I recall correctly. At that point, it becomes a real test of your sh programming skillz. :-)

      Of course, if you've got a fully loaded statically compiled zsh 4, you're home free. It's got builtin chown,chmod,etc.


    • openbsd turned me on to /altroot which is an unmounted backup of the root filesystem. very nice to have when bad things happen.

      I put the /altroot partition at the front of the second disk so if the root disk fails/breaks ... I can just boot and run again off the second.
