Boot prompt hyphens
- by purjuntu
Booting an Ubuntu DVD, pressing F6 and then ESC presents the boot prompt with the default kernel options, with the possibility of editing and adding extra options. Something like:
kernel /casper/vmlinuz boot=casper quiet splash --
Questions:
What's the meaning of the two hyphens?
When adding an extra option (such as "toram" or "vga=791"), is there any difference between adding it BEFORE or AFTER the hyphens?
When typing commands in Bash, two hyphens in a row means "options end here; anything that follows should be treated as an argument, even if it starts with a hyphen". But the hyphens must have another meaning at the boot prompt, as "toram" or "vga=791" really are options.
