I just adore the install. Esp. of GRUB.
Does *anyone* who works on GRUB actually work in the real world, and not
only on brand new machines?
I just had happen at work what happened last fall on my home system: then,
I had /dev/hda, and was trying a clean install on a new SATA drive; right
now, I'm installing on a replacement disk on a server that has no CD/DVD
drive from a USB key. My options: on my home system, it was MRR on
/dev/hda (which was being replaced, and was to become my backup drive),
and here, in the MBR of the USB key; in both cases, *only* in the first
sector of a partition on the new drive. I am NEVER OFFERED THE OPTION of
the MBR of the drive I'm installing to.
*snarl*
mark "no grub, then linux rescue, then chcon, then grub install...
I hope"

Googling, and using the hostile find, I set root (hd0,0), and then setup (hd0). It claims everything is wonderful... but when I reboot, I go back to the grub shell.>From the grub shell, I've also tried telling it kernel/vmlinuz-2.6.18-194.3.1.el5, and it claims it can't find that; neither can find. This is *so* much more sophisticated than changing lilo.conf, and running lilo to update the MBR.... And no, I have no choice, this is work, so I have to use the mandated grub. mark
