I made a mess. libc

[Teske, Devin]

Is it the base machine that won't boot? I got this ...

My latest version of Druid has a very sophisticated "Interactive Disk Repair" script that will assemble your system "humpty-dumpty style" while booted from a CD or Thumb drive (you said you couldn't burn a CD, but it wasn't clear whether you could master a thumb drive).

http://sourceforge.net/projects/druidbsd/files/FreeBSD-8.3_Druid-1.0b60.iso/download

When you run the "Interactive Disk Repair (IDR) Shell" option, it presents you with a few questions (like, "I've found a saved network interface in rc.conf(5) -- would you like me to activate it for you?"), and ultimately mounts your system to present a working shell to fix your problems.

Important: when it asks you if you want to chroot into the mounted filesystem, say NO (you're libc isn't working, so that would be a bad idea) -- rather, run from the LiveFS environment where /mnt is your mounted system. There's even a copy of libc in the LiveFS environment that you can copy over your old one...

cp /cdrom/freebsd/rescue/lib/libc.so.7 /mnt/lib/libc.so.7

(if I recall correctly)

That was very nice of you, but how do I get the file into my machine?
