対話式でのシステムのブートは、元のファイルが破損しているか、システムがブートしないために、ブートプロセス中に代替カーネルまたは /etc/system ファイルを指定する必要がある場合に役立ちます。システムを対話式でブートするには、次の手順を使用します。
次の手順では、ブート環境が 1 つしかないシステムの対話式のブート時に、代替の /etc/system ファイルを指定する方法について説明します。または、代替ブート環境をブートできます。
# cp /etc/system /etc/system.bak # cp /boot/solaris/filelist.ramdisk /boot/solaris/filelist.ramdisk.orig # echo "etc/system.bak" >> /boot/solaris/filelist.ramdisk
Name of system file [etc/system]: /etc/system.bak
情報を指定せずに Return キーを押すと、システムのデフォルトが受け入れられます。
# reboot
次の例では、システムのデフォルト (角かっこ [] で示す) が受け入れられます。
# init 0
