Re: Results of the second run of research about ext4 support in bootloaders
Hello, May I ask what would it take to have the Gujin bootloader added to this list, URL: http://gujin.sourceforge.net. It is a "newer" bootloader, but there isn't any Debian package for it, I have never made a Debian package before. Just fetching the source code and typing "make" will produce the "./gujin" executable on ia32 and amd64, and this executable is able to make partition, disk, disk image bootable. It does support quite a few filesystems, including EXT4 as long as it has constant inode size (dealing with one file with a different inode size means scanning all inodes at "mount time"). Different bootloader do things differently, anyone can find good and bad points about any of them - let's point to one thing Gujin can do to improve Debian: Problem: a lot of small PC no more have a CD/DVD drive to save space, and a lot of them only boot the "superfloppy" format out of USB thumb disks or SD cards (i.e. the PC will not boot if there is a partition in the partition table, usually meaning C/H/S description is in the boot record). Tested solution to install Debian on such a PC: - download the small ISO image: debian-501-i386-businesscard.iso - download and rebuild Gujin, or download the precompiled (ia32): http://www.mirrorservice.org/sites/download.sourceforge.net/pub/sourceforge/g/gu/gujin/install-2.6.tar.gz/install/gujin?extract=true or (amd64) http://www.mirrorservice.org/sites/download.sourceforge.net/pub/sourceforge/g/gu/gujin/install-2.6.tar.gz/install/gujin64?extract=true - type "./gujin debian-501-i386-businesscard.iso", it will modify the first 512 bytes (previously empty) of the image and add approx 300 Kbytes at the end of the image, nothing else. - type (USB disk as /dev/sdg will be fully erased, replace sdg as needed): umount /dev/sdg* cat debian-501-i386-businesscard.iso > /dev/sdg sync That USB superfloppy will boot (for instance an EeePc) as El-Torito, start the usual installation system - the only trick from there is in the installer "Detect and mount CD-ROM": -> No common CD-ROM drive was detected Load CD-ROM drivers from removeable media: No Manually select a CD-ROM module and device: No Inatallation step failed. Control Alt F2: return mount -t iso9660 /dev/sdb /cdrom Control Alt F5 -> Restart install at "load installer compoments from CD" Obviously this problem could be solved so that Debian would distribute a dual superfloppy/ISO image, where user would only need to do: cat debian-501-i386-businesscard.iso > /dev/sdg ; sync That would also simplify the docs at: http://d-i.alioth.debian.org/manual/en.i386/ch04s03.html mostly because those instructions generates a device with a partition table, which will not boot on the kind of PC described (for instance my EeePc).

I think that if user selected ext4 for the partition that will have /boot we ought to show a error message so user can react to it. I'm unsure if it has been dealed by current patches commited by Colin but I think it is not. -- Otavio Salvador O.S.

Results of the second run of research about ext4 support in bootloaders
Hi all, I continued my research about ext4 support in bootloaders and this is the result till now: ext4 support * grub: amd64, i386, powerpc w/ ubuntu patch * grub2: amd64, i386, powerpc * lilo-installer: amd64 i386 Looks without ext4 support * aboot: alpha * yaboot: powerpc * arcboot: mips * silo: sparc * delo: mipsel * sibyl: mips, mipsel * prep: powerpc * palo: hppa I based my search on the debian-installer list of packages that install a boot loader if there is obsolete packages among this list or if I forgot some please tell me. I searched through mailing list archives and sometimes into code. Many of the bootloaders in the second list looks unmaintained.
