#75 change Restart to clear out single-user mode

[Dan Adams]

I've just found out that if you force single-user mode via ard (Apple Remote Desktop) as root:
nvram boot-args="-s"
reboot

you can have applejack reset those parameters by changing the following in:
/var/root/library/Scripts/applejack.sh

from

function restart() {
loggit -n "Restarting hostname"
countDown
loggit "$GOODBYE"
loggit ""
reboot
}

to

function restart() {
loggit -n "Restarting hostname"
countDown
loggit "$GOODBYE"
loggit ""
nvram boot-args=" "
reboot
}

I was just able to ard a machine, to get it to restart in single-user mode, run the script manually, then restart into gui.

It's as simple as changing one line in applejack.sh

Thanks for your consideration.

This is interesting. And thanks for the code!

Here's the problem though. Doing so would mean that AppleJack would clear out the nvram boot-args. What if a user has a setting in there that they want to leave in place?

What we would need to do is, at startup of AppleJack, see what is in the boot-args, assign that to a variable, and then, at the end, filter out the -s from the variable and then re-write the rest to the boot-args.

However, there is yet one more issue. What do I do about the user who wants to keep his or her machine set to -s?

I don't want to further complicate AppleJack by adding command line parameters. Can you think of a way of implementing this that would work for all users, with varying needs?

Thanks again for the suggestion.
