vax folks probably aren't the _most_ interested in current developments,

but i think most of them probably know, 16 years later, that we switched
from a.out to ELF.

-has switched its executable format from the old a.out format
-to ELF, the now more commonly used and supported format.
-Your old binaries will continue to work just fine.
-The installation procedure will try to take the necessary steps to
-accomplish this.
-The most important step is to move the old a.out shared libraries in
-.Pa /usr/lib
-and
-.Pa /usr/X11R6/lib
-(if X was installed) to
-.Pa /emul/aout ,
-where they will be automatically found if an older a.out binary
-is executed.
-.Ic sysinst
-will use an existing
-.Pa /emul
-and / or
-.Pa /emul/aout
-directory if available, and will create it (as a symbolic link to
-.Pa /usr/aout )
-if necessary.
-.Pp
-If you already had a
-.Pa /emul
-directory, or a symbolic link by that name,
-.Ic sysinst
-should rename it and tell you about it.
