at the time, but on further reflection..." bucket with these changes.
1. Checking the media before frobbing the disks was a fine idea, and
I wish it could have worked, but that leads to a rather difficult
situation when you need to mount the media someplace and you're about
to:
a) Chroot away from your present root.
b) Newfs the root to be.
You're basically screwed since there's no place to stick the mount
point where it will be found following the newfs/chroot (and eliminating
the chroot in favor of just using the "root bias" feature would work
great for the distributions but not the pkg_add calls done by the
package installer).
2. Automatic timeout handling. I don't know why, but alarm() frequently
returns no residual even when the alarm didn't go off, which defies
the man page but hey, since when was that so unusual? Take out timeouts
but retain the code which temporarily replaces the SIGINT handler in
favor of a more media-specific handler. This way, at least, if it's hanging
you can at least whap it. I think the timeout code would have been losing
over *really slow* links anyway, so it's probably best that it go.
This should fix NFS, tape & CDROM installs again (serves me right for getting
complacent and using just the FTP installs in my testing).
more consistant in our use of the terms for differentiation between PC
partitions and traditional BSD partitions.

section was a good thing, since it made it possible to detect media problems
*before* the installation started, but it also caused various things to
be mounted BEFORE the chroot() call, which definitely messes things up.
Fix this by detecting the pre-chroot() case and mounting into a subdir.
This will probably need to go away again someday when distributions get
folded into packages and there are no more dist files to check, but knowing
how long we've been waiting on THAT, this will be a welcome tool for the
interim.

We could also make this stuff only come out when getpid() != 1
and thus avoid the install case (where it really is just too verbose,
and people have complained), but this seems less messy and no one
complained when tzsetup didn't print the final "things went fine!"
messages (which sort of contravene the UNIX spirit of only yelling
when you need to anyway).
Use setusercontext() rather than setuid()/setgid()/setlogin()/initgroups()
which is all handled. Login environment is NOT set by this call as crontab
provides its own means of doing so.
yp_next_record() is called without a key (from xdr_my_ypresp_all()),
in which case it returns the first key in the map. When doing this,
it also needs to update the key index in the map queue entry. Without
this, ypproc_all_2_svc() (and hence ypcat) don't work correctly.

- Use MAP_FAILED instead of the constant -1 to indicate
failure (required by POSIX).
- Removed flag arguments of '0' (required by POSIX).
- Fixed code which expected an error return of 0.
- Fixed code which thought any address with the high bit set
was an error.
- Check for failure where no checks were present.
Discussed with: bde
going into SLIP mode, useful for scripts that can automatically
grok IP addresses ala Trumpet Winsock.
