From the solution of 5515, it seems that in order for me to get into rescue mode, I must either have the CD-ROM or have the RedHat directories sitting on my hard drive somewhere. I borrowed a CD from someone to upgrade to 6.1, so I have neither (just a boot disk). When I tried typing "linux rescue" with the install boot disk, it insists that I must either have the Red Hat CD-ROM or the directories in my hard drive. I don't know if this is a bug or a feature, but I believe that people who don't have the Red Hat directories handy should still be able to get into rescue mode (e.g. people doing ftp installs).
The rescue images are available to anyone performing any of the installation methods. So, for someone that is performing a FTP installation, they can boot the bootnet.img file with the "linux rescue" option and the installer will ask where to retrieve the rescue image from. The user would just enter the address of the FTP server and the installer would retrieve the rescue image from there.
I disagree. If someone doesn't have access to the installation medium any more (e.g. if someone hooked up temporarily to the net just to install RH), then there is no way to enter rescue mode. IMHO, one should be able to enter rescue mode as long as the floppy drive is working. Maybe RH should produce a stripped down version of a rescue floppy (such as those in the pre-6.1 days) so people in real trouble can actually get into rescue mode.
If the install medium is not available, the user can boot from the system boot disk (not the install one, but rather the boot disk made the installation or with the mkbootdisk command) with the "linux rescue" boot parameter and make use of the 6.0 rescue.img file. We are working to put together a rescue.img for the 6.1 distribution which can be used in the same way, but until then, the 6.0 rescue.img works great.
Has the new 6.1 rescue.img been completed?
