Flo, thanks for the info. I checked the kernel-image dir and indeed i found a lot of files there. However, i only found one reference to cramfs and it was in README.Debian.1st.gz: Quote: " * Added initrd support for cramfs in init/do_mounts.c * Set time fields to zero in fs/cramfs/inode.c " I didn't find anything regarding cramfs patches so i guess the changes necessary for Debian are located in the 2 files described above and there probably isn't a patch that one can download to do this. Now, this should be a problem in cramfs isn't needed by a Debian initrd. That i don't know. Then i went on to search in the kernel-source-2.4.21 directory. The kernel-source-2.4.21 directory contains also a lot of files and there are some more comments on cramfs. The debian.README.gz file has more info on initrd: Quote: "... and make sure that you have applied the cramfs initrd patch to the kernel sources (or modified mkinitrd config not to create a cramfs initrd) The cramfs initrd patch is shipped with Debian Kernel sources" That's all i've found on cramfs. The person on this list was using LVM which has it's own initrd creating script (lvmcreate_initrd) and i don't think it uses cramfs so in that case he should be ok to create a kernel from the vanilla sources. In the other case, he could adjust /etc/mkinitrd/mkinitrd.conf to not use cramfs when creating an initrd by changing the MKIMAGE setting in mkinitrd.conf. Not sure what you could add instead. I've seen references to but i'm not sure if this produces a working kernel: MKIMAGE='genromfs -f /dev/fd/1 -d %s | gzip -9 > %s' I then found http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=149236 Quote: " Please read th description of initrd-tools. It only works with Debian. The patch is listed in the README file of kernel-source. Herbert Xu" Well, i went over to the kernel-sources-2.4.21 and i checked the README (i think he means README.gz) and i didn't find any reference too cramfs either. The original bug filer apparently also had problems with the rather obscure references to the cramfs patch that nobody seems able to find. It's bad timing as a lot of people want to compile vanilla kernels sources yet are blocked because they can't find any link to that patch. They then refer too: kernel-package_8.005.dsc to pool/main/k/kernel-package/kernel-package_8.005.dsc kernel-package_8.005.tar.gz to pool/main/k/kernel-package/kernel-package_8.005.tar.gz kernel-package_8.005_all.deb to pool/main/k/kernel-package/kernel-package_8.005_all.deb I then tried to see if i could use apt-cache search to find something regarding cramfs but it ended up with cramfsprogs and mkcramfs. apt-cache search kernel-patch | grep cramfs doesn't result in anything. It seems as if the Debian archives is the only place where you can get this patch. So: Where is this patch hiding and how can you get it?
