My friend uses a typical dual-boot setup (Windows XP and Centos 5.3). The machine is online 24/7 and he often uses it from a remote location (Linux via ssh -X, Windows via rdesktop).
The problem is that he wants to be able to remotely configure which of these two OSes is to be the default on next reboot, so he can switch from one OS to the other and back remotely. If Linux is up, he just needs to reconfigure grub.conf, but if Windows is up (and default) he has no way of accessing grub.conf.
Now, he has several partitions on the drive, some ntfs, some vfat and some ext3. Is there a clean way of putting grub.conf on a vfat partition? Is there a way for Windows to have rw access to ext3 filesystem (namely, /)? Is there some other way of handling this without physical access to the machine while it boots?
I have suggested virtualization of Windows, so he could run them both concurrently without pain, but for certain (computational performance) reasons that is not a good option for him --- he wants hard reboots between OSes.
Any suggestions?
Thanks! :-) Marko
I have not done this, but maybe a small vfat partition with syslinux instead of grub as the boot loader. Then you could edit the configuration from both Windows and Linux.
It might also be a good idea for him to look into one of these single-port IP/KVMs in case he needs to get to the console: http://www.lantronix.com/it-management/kvm-over-ip/securelinx-spider.html
