Following that personal E-mail question: I'm an Ubuntu user & would like to replace GRUB2 - and would also like to be able to have a couple of utility ISOs bootable from the HDD. Will your Gujin still do all these things with the latest versions of Ubuntu ?? Reply: The answer is "yes and no", it is not depending on what you are booting, but on your PC. If your PC is booting UEFI, Gujin cannot help because it relies on the older BIOS and your PC will not consider even running Gujin. If your PC is...

Hello Abac, 1) and 3) might be due to a lack of malloc() memory - i.e. not enough memory in the 64 Kbytes segment containning data. I think you can display the "command file" by typing "C" when Gujin show you the menu, it would tell if malloc() failed and the file was ignored. All found command files are treated (stripped of comments, ...) when they are found (while probing filesystems) and concatenated into a variable size buffer, then matched depending on filenames at Linux loading. That is what...

You are welcomed, the BIOS system has had a lot of stuff added over the years, it is a bit complex but usually there is a way to get where you want to be. EFI bios may be butyfull (displaying a nice graphic) but when it doesn't work there is no way to know what happened.

I am not sure why my reply did not appeared here... There are few distro which can boot in a mode where Gujin extract vmlinuz/initrd from the partition or the ISO, and then Gujin can pass a Linux command line parameter like "isofrom=". The real distro independant system would be to use that "gujin.sh" inside the distro initrd, and then the distro always knows where it has been loaded from (even if Gujin did not extract vmlinuz/initrd but started the El-Torito bootloader). Obviously there is no command...

There is a way to ... tell the distro where to search (by dev/ address or UUID) the root file system? Yes, for every Linux distro which uses Casper (Ubuntu, ...) it is https://code.launchpad.net/~etienne-lorrain/casper/gujin For most other distro, they can find where they booted from with the shell script "gujin.sh" in the source gujin-2.8.7.tar.gz, I have tested it on Fedora and few other distributions. I hope I documented it properly - but because it is used when the initrd control files are executed,...

So Gparted uses an external root filesystem, I was thinking Gparted would have its whole root filesystem contained in its initrd, I was wrong.
-
Some ISO are a bit special, probably Gparted is loaded entirely into memory by the bootloader (whatever the bootloader is) and never needs to access its iso file again, so there should not be any problem. But a Linux distribution will only be partly loaded: the kernel and initrd are in memory once the bootloader finishes, usually the initrd is then tasked to find "the" root filesystem, and that code do not assume (without my Linux patch) that there may be multiple root filesystems arround. There...

Hi Abac, and sorry for the late answer. The first problem you have is due to the distribution itself not being able to detect its own root filesystem. Even if Gujin do tell where to find it, it will ignore the hint provided by Gujin and get the first root filesystem it finds - unless the patch I provided (and you found) is applied. You have noticed it because you tried to mix two distributions root filesystems (and I do agree it is a dirty solution). The problems you encounter all come down to this...
