Booting from the CentOS 5.2 Installation DVD (or the first Installation CD), one can type "linux rescue" and then "chroot /mnt/sysimage" and have full root access to the OS on the HD. For future reference, I would like to know what I did wrong, the past couple of days, when trying to use the CentOS 5.2 i386 Live CD, for rescue. From a terminal, "su -" did not seem to get me root access to the hard drive. What command should I have used, with the Live CD? The access I had was read only. (As it turns out, I could have fixed the problem, without the LiveCD, but I didn't know that, 3 days ago.... :-) ) TIA. Lanny
<snip (output of mount command)
the boot partition, /dev/hda2 was mounted Read-Only (ro). To work around that little problem, simply: # mount /dev/hda2 -o rw,remount which remounts the partition Read-Write so you can work with it instead of only observe.
Thanks!
Now, I believe the Live CD is missing the chroot command. This means you have to do the "bookkeeping" manually. The grub.conf file (normally at /boot/grub/grub.conf) will now appear at /mnt/disc/hda2/grub/grub.conf. Note that there is no "/boot" in that path.
Yes. The paths were very different, when running on the Live CD.
And yes, the farther you are from the monitor, the clearer it all becomes.
Many years ago, I bought a handheld VHF radio transceiver. In the manual, is said something like, "if you get frustrated, put the radio down and go get a cup of coffee". Distance from the problem frequently helps... I appreciate your input!
