Hi,
I have in a boot image a script which ends by:
…
sh /etc/rc.d/rc.sysinit
sh
}
I want the last sh invoked only if I cannot execute rc.sysinit succesfully.
the rc.sysinit ends by ‘tinit’ which runs as a background process.
What can I put at the end of rc.sysinit to not leave it?
I tried ‘wait’, but I get:
sh: j_init: tcgetpgrp() failed: Inappropriate I/O control operation
sh: warning: won’t have full job control
Thanks,
Alain.

I didn’t find how to do!
exec is not a startup-script command so I cannot ‘exec
/etc/rc.d/rc.sysinit’ in, and as tinit runs as a background program (I
think) ‘exec tinit’ in /etc/rc.d/rc.sysinit doesn’t change its
behaviour, the shell script continues.
Any other idea?
I still get the following message now:
sh: j_init: tcgetpgrp() failed: Inappropriate I/O operation
sh: warning: won’t have full job control
Do you know who displays that?

This message comes from the shell (ksh)

Right, sorry – forgot you were talking in a a boot script.
Unfortunately, the boot script doesn’t have any sort of conditional
test or branch type operations in it.
and as tinit runs as a background program (I

behaviour, the shell script continues.
Hm…tinit probably daemonizes itself, yeah.
Any other idea?
About the only way would be to write a little C program that does
this – that runs the startup-script, and if that fails, runs a
shell instead.
I still get the following message now:
sh: j_init: tcgetpgrp() failed: Inappropriate I/O operation
sh: warning: won’t have full job control
Try
[+session] sh
Do you know who displays that?
The shell (sh) does.

You might need:
reopen /dev/con1
[+session] sh
Where /dev/con1 could be /dev/ser1, or whatever your “console” for the
machine is, and assumes you’ve started a serial port or console driver
before you get to this point. (Or, you may already have done the reopen,
and not need it.)
