Hi, I'm using initramfs with pivot_root mechanism to mount my real root directory. I notived the gentoo halt.sh script tries to unmount everything on shutdown. That includes /initrd. The kernel seems to freeze immideatly. Do you have the same problems? Regards, Andreas CONFIG_X86=y CONFIG_MMU=y CONFIG_UID16=y CONFIG_GENERIC_ISA_DMA=y CONFIG_GENERIC_IOMAP=y CONFIG_CLEAN_COMPILE=y

working fine with glibc. thanks!

Hi, please correct me if I'm wrong: - the kernel needs enough ram for the compressed initramfs and the same files decompressed, so it can decompress the files and boot the /init on the initramfs. - if the kernel does not have enough ram, it will kernel panic. my tests were done on a server with 256 mb ram and a 80MB compressed initrd. I removed some packages and now it fits and the

a bit unrelated, still I wonder: does syslinux contain an mbr? or does anyone know any app that contains an mbr and can install it, without overwriting the partition table? my experience is, that is wise to have an mbr and use the active flag to select the active partition (which might have a bootmanager installed). however every linux distribution I know installed the bootloader such as

Hi I had some doubts regarding what all the init application should do: >> so, that should that application do? >> - mount /dev/hda1 /new-root >> - cd /new-root >> - run-init 1. Of what I understand, before exitting, init should mount the realroot and execute the init process. Is realroot the '/' or the empty directory created (in the cpio archive) ?

Hi All, I am trying to start a lxc container using libvirt and I am facing an issue due to pivot_root. The return code from the system call ?pivot_root? is EINVAL (Invalid arguments). I isolated the issue to this specific condition check within the system call. This is an code snippet from fs/namespace.c::pivot_root * error = -EINVAL; if (root.mnt->mnt_root != root.dentry)

Hi, What is the difference between chroot & pivot_root. They don't seem obvious based on the man pages apart from the below mentioned caveats. 1) Inherited Open file descriptors, have to be explicitly closed. 2) Does not change CWD of the process, which can be overcome by doing a chdir before & after chroot call. Any information on this would be useful. Thanks,

Hi I am looking at inserting functions in the early user space and want to use initramfs for this. I understand this can be achieved using 'initrd' or by making changes in the 'usr/gen_init_cpio.c' file. Can someone kindly give me pointers as to how to go about this. I am looking at the 2.6.x kernel. Thanks Rachita.

Hello, I'm new in ext3. I installed RH7.2 with ext3. For a short time it worked properly, but when I compiled the linux kernel (2.4.9-13) from RH package, the old kernel didn't boot again (I didn't change anything with the old binary). I downloaded kernel 2.4.14 and ext3 patch for this version. After the compilation and installation I rebooted the system. I got answer something

Hi 1. Is it possible to load an initrd from initramfs ? How would you do this if the initramfs is being loaded dynamically in the kernel (ie having the initramfs as initrd ) Because in this case, you will say root = /dev/initrd and specify 'initrd' as your 'initramfs source file' How will you specify the second initrd source? Thanks Rachita.

Hi, Here's a try at writing an initramfs HOWTO. This is basically a write-up of a number of interesting emails I collected over time. It could probably use an editor, more fact-checking and a bunch of other good things, but it should be better than nothing ;-) Daniel -------------- next part -------------- INITRAMFS HOWTO 0) What are klibc and initramfs? Initramfs is a ramfs into which

I converted my lvm root initrd to an initramfs by putting glibc, lvm, pivot_root, my linuxrc, etc. in my initramfs source file. I use ash compiled against klibc to run my linuxrc Unfortunately - pivot_root . initrd - complains - pivot_root: Invalid argument I suspect this may be because you can't pivot_root using a cpio initramfs root? If so, what should I do instead? Should I

A patch for a few more hiccups and trivialities in kinit.c: * The check_path() calls check for "/root" and "/old_root" - I believe that should be "/root" and "/root/old_root". * chdir("/") is recommended after pivot_root() * init_argv[0] isn't set properly to the basename pointed to by char *s - this fix also eliminates six lines of

Hi Currently I am trying to get device-mapper and dmraid ported to compile against klibc. So far there was no real issues, as the only thing they used was fscanf and feof not available presently in klibc (but easy to work around). Other than that there are really no way to easily check for installed klibc's other than trying to mangle the output of klcc (from adjusted configure.in): -----

Hi, If say ppc where LDFLAGS=, you get the problem that klcc is generated like: ----- @LDFLAGS = ( '' ) ----- which then causes '' to get passed to ld, which gives: ----- /usr/bin/ld: : No such file: No such file or directory ----- One of two ways (I tried over here at least) to fix it, namely the quick hack: ----- --- 1/makeklcc.pl 2005-03-10 00:22:03.000000000 +0200

Hi everybody, I had a problem which you may be interested in. I set data=writeback in /etc/fstab for each of my ext3 partitions (because it complains on "mount -o remount,data=writeback" with "ext3: journal mode can't be altered on remount" or similar) and rebooted. Problem: / was mounted read-only, I couldn't remount it (because mount appends the options from fstab,

I've been working on a buildrelease.sh script to call hg2dist.sh, export debian/ from svn and run dpkg-source for me. When I ran dpkg-source I noticed that it gave warnings regarding the *.dpatch files being chmod 0755 is there any reason to maintain this within the repository or would 0644 suffice and remove these warnings from dpkg-source?
