How can I load OpenSolaris x86 in single user mode?

Modern OpenSolaris is configured to prohibit root login during normal boot. This is only possible in single-user mode. However, many online instructions simply say to add ā€œ-sā€ to the end of the default grub boot arguments, which leaves the boot graphical display in an infinite loop and never enters the console with single user mode.

The key point left by many OpenSolaris single-user instructions is that you should change the boot grub text entry, not the default image entry. Downloading in graphical mode with a single-user switch forever leaves the download progress schedule overlaid on the console, never allowing the maintenance console to be visible.

  • Reboot
  • At the grub prompt, highlight the most recent text boot entry and press e .
  • Highlight the line starting with kernel$ and press ' e '.
  • Add ' -s ' to the end of the line.

eg. edit:

 kernel$ /platform/i86pc/kernel/$ISADIR/unix -Bv$ZFS-BOOTFS

to

 kernel$ /platform/i86pc/kernel/$ISADIR/unix -Bv$ZFS-BOOTFS -s
  • Press ' enter '.
  • Press ' b ' to download.

The system should boot without graphical overlays and should quickly arrive at the system maintenance console.
