[CentOS] Re: Rescue mode

[Denis Machard]

Thank.  
Indeed, I would like to mount the cdrom device to access an rpm.   
For specifical needs,  I try to add the support of perl and sshd on rescue
mode.

I just tried this, and for some reason, there are scsi devices present, but
not IDE devices. If you need them, you would need to chroot to your
underlying system to use them from there.
 The only reason I could see to need to mount a cdrom would be to access an
rpm or two. You would need your system mounted under /mnt/sysimage anyway.
If your system isn't intact enough to do this, then you would need to
salvage as much data as possible before attempting to fix it, and that can
be done over the network, or with the "live cd".
