hi,
just wondering if its possible to install parsix with it making references to its system files based on a relative partition, rather than an absolute partition.
the reason i ask, is that i've got several logical partitions, one of which is parsix. it seems, that when u add/delete logical partitions, the logical partition numbers of partitions left alone (such as parsix) still change sometimes.
i do a lot of adding/deleting partitions as i use 'gujin' to load distros from harddisk rather than burn them to cd's.
i just installed dreamlinux on another new logical partition, and parsix now freezes in the middle of loading up + the grub doesn't work at all.
if it was possible to install parsix with relative reference to it's own partition, this would solve all such problems; but i'm not sure if this can ever be made possible - or perhaps one day in the future?  |

I don't exactly know what you are trying to do but I have multible distros as I test them. I install grub on the master distro to mbr, then guest distro's to their root partition then just enter them to the master boot grub Menu 1st, that way they never alter anything, then when you want to remove them its simple. always install from a live cd/dvd/ usb stick. you need a unmounted partitions to install, warning Gentoo, Fedora, pclinux, do not like sharing grub with other Linux distros. that why I always mount grub on root. I personally use Sidux as the master distro. Then add the grub entries to / grub menu 1st
## ## End Default Options ##

as you can see at the moment I am running Parsix, Sidux, Debian, + windows
you can as I have place your entries to suit your preferences |

my ideal scenario would be:
distro 1 grub installed on mbr.
distro 2,3,... grub installed on each partition.
mbr grub does not need to be changed or added to with installation of new distros, as it will simply point to each partition, which will load it's own root grub...
title Distro 3 (sda3)
rootnoverify (hd0,2)
makeactive
chainloader +1
my question was then referring to the root grub on sda3. instead of it pointing to 'sda3' with the fstab doing the same. it simply pointed at 'itself', whichever partition number it happens to be.
kind of how VB programming, can point at 'me' for its current form, or how windows will just load from whichever physical partition it's currently on, even if number has changed.
this may not be possible in linux, but it would be great if it could. |

| If you read what I said you will see that on my system each distro has its own grub on its own partition. Grub on mbr merely points you to the partition and entries can be added or removed with no adverse effect As for windows it also uses entries on mbr. which like grub points to the partition windows is always C partition so it looks for C. if you put 6 windows XP on 6 partitions you would need 6 entries in chainloader to access each separately it would not read your mind, that's the same for Linux please do not try not to compare the two most people come to Linux with vast Windows experience but find the advantages of Linux out-way windows by a fair margin that's why they use it. Linux has a learning curve the time it takes to learn depends on the individual and how fast they grasp the fact that it not windows it can never be windows and things are done the Linux way not the windows way. After 2 years of Linux I still have a lot to learn..Parsix has been on my system since December 2007 and since then my main distro. |

hi md,
i did read that you were installing grub on root partitions aswell. whether u change the master grub menu.lst or leave it as pointing to root partition grubs is not a massive issue either.
Wasn't trying to do a big linux/window compare, but just noting that windows doesn't actually change the mbr. what it does, is use a standard mbr that points to the active primary partition - which happens to be windows. windows then runs, whichever partition number it is at. as such, there is no absolute reference to a partition number. of course, this is only the scenario if only 1 installation per disk.
there's lots of things windows can't do that linux can, such as boot from logical partitions - so i didn't mean it to be another linux v windows issue.
I just wanted to check if there was any way to bypass absolute values to own partition in fstab or menu.lst
