If installing from a pmax diskimage as both current root and target root,
the diskimage /usr/bin/tar is hidden underneath the target /usr mountpoint
when it's time to untar distribution files. From a comment in the change:
Make sure any binaries in a diskimage /usrbin get copied
into the current root's /usr/bin. (may be same as target /usr/bin.)
The rest of sysinst uses /usr/bin/{tar,ftp,chgrp}.
We cannot ship those in /usr/bin, because if we did
an install with target root == current root, they'd
be be hidden under the target's /usr filesystem.
Requires updated diskimage build script which populates /usrbin with
tar, gzip, gunzip, ftp, and chgrp (all statically linked.)
- use board address space > 4 MB, instead of iszthreepa(), to detect Z3-mode
boards. We dont want the bus, but want the address configuration.

and current-root-is-target-root (pmax diskimage.
* Add code to check disk names (e.g., "sd0") against the current
kern.root_device sysctl (whic does *not* include a partition).
* Add new function must_mount_root():
check to see if it's the same device as the root. If not,
the current and target root partitions cannot overlap.
If they do, do statfs() on "/", and return 1 iff we get back
"root_device" as the mounted-on filesystem, otherwise zero.
* Call must_mount_root() right after the user specifies a disk as
install/upgrade target, and if it returns 1, print a message asking
them to mount root, and abort.
* Use statfs("/") mounted_from string to check if a disk partition
(e.g., "sd0a") matches the current root.
* Add code to query CDs for size, from MI scsi cd.c. Use it on CDs.
* Set C partition size for CDs. 4.4bsd/pmax code only set `a' partition
size and required users to mount `a' partition, breking raw-device
access like "disklabel rz?".
* Avoid possible divide-by-zero call to howmany() from rzstart(),
on removable media that aren't ready at device-open time.
Verified to work on rrz42.
until a proper fix is available:
Perpetuate the 4.4bsd design even further. Change keyboard-driver
open routines to check for an active raster console. If active, set the
keyboard struct tty's t_winsize from the rcons t_winsize on first open.
See pr 4438 for remaining problems and discussion of a complete fix.
i've fixed a lot of bugs in it):
* implement yp_close_map(struct opt_map *), to close a specific map,
using the guts of yp_close_last()
* simplify yp_close_last() to use yp_close_map()
* ypdb_open_db(): add the st_dev, st_ino, and st_mtime of each map to
the cached info, and check if changes if the db is cached; if so, close
the map and reopen it fresh. also uncache entries if the domain or
file disappear
* add includes for sys/dev/scsipi headers.
* cut-and-paste mode_sense and disk-geometry sense code from sd.c,
with name changes sd -> rz.
* Write `rz_command()' to send SCSI sense commands based on
existing rz size-sensing code.
* get geometry info with page 4 and page 5 mode sense.
* use resulting geom info for default label, fake label, and when
using ultrix labels. (ultrix labels have no geometry info).
Fixes incrrect-label bugs with using sysinst to install onto
Ultrix-labelled disks.
