what does recovery mode kernel do?

#1 Postby JBoman » Thu Feb 23, 2012 2:09 pm

Curious, at the bootsplash screen at bootup for each kernel listed there is an option just under each one for the same kernel but in (recovery mode). Would like to know what the difference is and what the kernel in recovery mode actuall does if anything. Thanks, :snail: Jerry

The kernel in and of itself does not change anything or do anything extra for you, it simply gives you a command line login in I think run level 1 (single user), which for centuries (in computer terms) has been the default recovery starting point.

Most desktop Linux systems as run by the majority of users today operate at run level is 5, multi user with GUI, most servers operate at run level 3, multi user, command line only, which makes them incredibly efficient.

I'm assuming this is a grub menu created by the update-grub command.

I have a couple '.... (recovery mode)' stanzas on a partition that's using grub2. The difference I see between the recovery mode stanzas and the regular ones is that the "single" {without quotes} kernel option is used.

Well, I thought that also but when I boot it it just boots as normal to the graphical login screen. I had assumed it was for for getting a root prompt to reset password but it is not working that way so I figured I would post the question and see if anyone knows for sure. :blindfold: Jerry
