Hi,
I'll be glad to. I am talking about 2 features.
1). a "boot" console, I mean, something that transfers tty i/o to a serial
console at boot time, i.e., the minute the kernel started loading. This
would be helpfull if fsck is unsuccesfull, or booting otherwise stops and
exits into a single user shell. This is offered by BSDi, and FreeBSD, I am
not aware of any Linux alike option. The advantage is you can control a
computer from remote before it boots, and not have to drive to the CC in
order to bring it up if fsck exited with an error code and dropped into a
shell.
2). If the computer gets stuck, for any reason whatsoever, you can send it
via a serial cable an escape sequence or signal that will generate a
system cold boot (it is a bios option, I heard it exists, I haven't seen
any yet).
I am interested in both features, in order to have reliable production
network servers running Linux.
