Most preference settings are saved in the installation history when you enter the quit command and are restored the next time that you invoke Inst. "The Preferences List" describes set preferences in detail.
The shroot command uses the chroot system call to invoke the shell as if /root were its root directory; that is, /root becomes / for all references. Thus files can be referred to with their normal pathnames (see "The sh and shroot Commands" and the chroot(2) reference page for additional information).
If you use stop while Inst is installing software, it makes a record of pending selections. At the next go command, Inst restarts the installation process on any uncompleted product installations, then continues processing the remaining selections that were pending.
Caution: Using the stop command during installation can leave software in an inconsistent state that requires a removal and reinstallation of the affected product.
