CVS commit: src/distrib/utils/sysinst

[David Laight <dsl%netbsd.org@localhost>]

Module Name:    src
Committed By:   dsl

Modified Files:
        src/distrib/utils/sysinst: main.c run.c

Log Message:
Remove extra process and pipe that relayed data from the master pty
to sysinst's main process when a command is run (eg the file list from pax).
Since the pty is in 'packet' mode, the boundaries of the pty reads would
need to be preserved in order to detect control records.
If the pipe became full the main process could treat part of a filename
as a control byte and then save the rest of the name as tty settings.
The effect of 'random' tty settings is unknown, but could be responsible
for core dumps while displaying the full file list from pax.
I suspect that the extra pipe was originally used because select wasn't
supported on the master side of a pty (not checked).

Also cd out of /targetroot if set installation is killed with ^C ^C.
