First, may I suggest that sendmail is probably not a mail server which many people want to use. It used to be horrendous to configure. I run postfix, which provides /usr/sbin/sendmail.

My thought process on trying to debug this With traditional sysvinit, the kernel has invoked init and that has gone into your chosen runlevel (probably runlevel 3?). I suggest that you begin by looking at the bootscript for sendmail, to see if it starts multiple programs. If it does, try adding messages between them. Alternatively, if sendmail really is running ok then the problem would be with the *next* script (ordered by the SNN symlink numbers). But if that next script begins to execute, I would expect it to report something. So this sounds to me as if sendmail is not completing. If you have enabled MagicSysRQ in your kernel, and your keyboard has a SysRq key (possibly on PrtScr - labels may differ slightly), you can probably force a reboot. For my desktops I think I use AltGr e(right Alt) and PrintScreen - hit the magic key combination for your keyboard, followed by s (sync), wait briefly, then use the magic key combination followed by b (boot) or, at the end of the session o (off). These will do unclean shutdowns, so next boot will fsck, but the Sync will update logs, particularly the system log and maybe the mail log, boot log (boot log tends to be not very informative). If you didn't enable that in your kernel config, wait a few minutes so that the logs have hopefully sync'd. 2. Recommendations, now you know how I've got them: As a first stage, from the host look at the LFS logs to see if there is anything useful. If there isn't, as root chmod 644 /mnt/lfs/etc/rc.d/init.d/sendmail so that you can read and edit it but it will not automatically run. If you are able to boot without sendmail, you should have a working keyboard on several ttys : from one of those, root can try starting sendmail, or just stepping through the invocation(s) in that bootscript [ i.e. run commands directly ]. Alternatively, and if you have NOT booted this system in LFS before you added the extra packages, perhaps you did not build the (correct) keyboard driver (usb and PS/2 might be different, I'm not sure). ĸen -- I live in a city.
