grub boot to "1" "S" or "single"
I have a silly (?) trivia question: what is the difference between appending "1" OR "S" or "single" to the end of the grub boot line?
I'm not sure single works, since i've pretty much only used 1 for a few years now, but i don't notice a difference between 1 and S, but vaguely recall that there was/should be/is some sort of difference. Any ideas? |
Do you mean appending a string "1", "S" or "single" to a line in a Grub boot configuration which reads as the string "boot"?
Code:
boot 1 Code:
boot single According to GRUB documentation, the boot command takes no arguments. I'd be surprised to hear that grub didn't complain about this -- if I have understood you correctly -- but in that case, then, none of them should have any particular effect. Are you referring to some argument to the kernel? http://www.mjmwired.net/kernel/Docum...parameters.txt ? |
I was talking about effectively modifying the kernel line in the /boot/grub/grub.conf file at boot time by editing it from grub.
The process is described for example here: http://kbase.redhat.com/faq/docs/DOC-9459 The kernel documentation only cites S , but not single or 1 ... so that doesn't clear anything up :) |
