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. 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, sysinst should rename it
|
|
|
|
|
and tell you about it.
