You mention FreeBSD later, so if something similar happens again, you
should be able to use the statically-linked binaries in /rescue to
recover from most shared-library problems, especially if you've got
another system you can NFS-mount to copy files from.  Surprisingly, ftp
isn't in there, so if you need executables or libraries from
ftp.freebsd.org you'd have to ftp them from another box and copy them
via USB drive or something similar.

In emergencies, I have used this as an ls replacement :)

ls() { echo ${@:-*} }
