So, no init system or anything? Your terminal probably hasn't been set up. This is a surprisingly tricky bit of "magic" done with a special syscall which we're for the most part happy to let some linux distribution do for us.
One workaround for it, funny enough, could be ssh-ing into your device. A virtual terminal should be close enough.
I was sure that busybox had a utility for it, and their faq turns out to have that and a better explanation what it does:
Quote:
"Why do I keep getting "sh: can't access tty; job control turned off" errors? Why doesn't Control-C work within my shell?"
Job control will be turned off since your shell can not obtain a controlling terminal. This typically happens when you run your shell on /dev/console. The kernel will not provide a controlling terminal on the /dev/console device. You should run your shell on a normal tty such as tty1 or ttyS0 and everything will work.
Example: you booted into your machine with init=/bin/sh and got "sh: can't access tty" error because sh has its stdio opened to /dev/console. You want to reopen stdio to, say, /dev/tty1 and thus acquire a controlling tty.

In Darwin, when typing "ifconfig en0 media 10baseT/UTP mediaopt half-duplex" I recieve the error message "ifconfig: SIOCSIFMEDIA: Operation not permitted". The same thing occurs when I sudo the command. Any suggestions?

itruns
itruns(8) System Manager's Manual itruns(8)NAME
itruns - set up files for use by the it command
SYNOPSIS
/sbin/itruns file [file...] in run-state [, file [file...] in run-state] [,...]
DESCRIPTION
The itruns program sets up scripts to be run by it(8). (These programs are typically used within system configuration and installation
scripts.) The itruns command searches for /sbin/it.d/bin/file. If itruns finds the file, it creates one or more symbolic links from
/sbin/it.d/run-state.d/file to /sbin/it.d/bin/file.
The run-state argument can be a single run state, or it can be two run states separated by either the word or or the word and. If two run
states are specified with the or keyword, itruns checks for (and creates, if necessary) a directory whose name combines both run states and
places a link in that directory so that the file will be executed when the it program detects either state. You can collapse two or-sepa-
rated states into a single expression; for example, 2 or 3 can be expressed as 23. If the and keyword is used, itruns checks for (and cre-
ates, if necessary) two separate directories and places a link in each of them so that either state triggers execution of the file indepen-
dently of the other state.
If two or more files are specified for a single run-state argument, links are created for all of the files as indicated by the run-state
argument.
If two or more combinations of files and run states are specified as comma-separated expressions, itruns treats each combination individu-
ally.
RESTRICTIONS
The itruns command must be executed from the root directory (/). The command finds only files that are located in the /sbin/it.d/bin direc-
tory.
EXAMPLES
This example sets up the doconfig script to be run when the system is booted to run state 2: itruns doconfig in 2 Either of the command
lines in this example sets up the doconfig and getdate scripts to be run when the system is booted to run state 2 or to run state 3: itruns
doconfig getdate in 2 or 3 itruns doconfig getdate in 23 This example sets up the doconfig script to be run when the system is booted to
run state 2 and again when the system comes to run state 3, the getdate script to be run only in run state 2, and the getsysname script to
be run only in run state 3: itruns doconfig in 2 and 3, getdate in 2, getsysname in 3
