Harcoding default content of initramfs in the gen_initramfs_list.sh script seems ackward. Move it to a file named: usr/initramfs.default This also fixes a small bug when no arguments was passed to CONFIG_INITRAMFS_SOURCE (-d was passed twice to the script) Idea and bug report from: "H. Peter Anvin" <hpa@zytor.com> Sig...

But with all the troubles this simple issue has caused me I woul not be suprised if there are some untested cornercase.

Hi, I am a newbie into kernel booting process. I have read few things about boot process of the linux kernel. I am stuck at few things, which I am confident, someone from the list might help on - - If I pass a ramfs image as an intrd paramter from the bootloader (say grub), then will the kernel treat this as a ramfs image only? - initrd image is also, packed using cpio archive, then how does the kernel come to know that this is an initrd ot initramfs image. Is there some type information included a...

gen_initramfs_list.sh failed to generate a dependency list when it was supplied the -d option. Restructured gen_initramfs_list.sh to support dependency info with -d. This also fixes a bug where we did not properly process when more than one dir was specified. Finally update dependency info for the -d case (list_...

Hello, I was using a bunch of cpios in initramfs as a working system, and wondering why the unused files weren't being paged out to swap. So I reread ramfs-rootfs-initramfs.txt and now I know. So I wrote the attached utility. It creates a tmpfs, moves all files on the initramfs, moves / and executes the real init. It works, even with hardl...

This is most exceedingly weird boot/shutdown sequence that I used once, and can't find a way to adapt to initramfs. Since you guys are trying to adapt all mechanisms that use initrd to using initramfs, this should interest you. initrd has (all binaries static): /bin: init halt mount poweroff pivot_root reboot sh umount /etc: fstab haltrc /dev: null zero tty tty0 tty1 console->tty0 hda1 loop0 ram0 /proc:...

These are some boot/rescue systems with ext3 support. The RIP boot/rescue system. This is a boot/rescue system, it comes in three versions. There's a bootable cd version that comes with kernel 2.4.6 and has IDE and SCSI support. rip-39.iso.bin 2528kb They can all be found here: http://www.tux.org/pub/people/kent-robotti/looplinux/rip/index.html There's more info at the above site.

...ilesystem quota had trouble since now user required twice as much available quota to save a message. The FS quota problem was "solved" by having quota-fs plugin change the default temp file path to /tmp. So why was the move made in the first place? Because a) some people had small (maybe ramfs) /tmp and Dovecot was eating it all up and b) to avoid any potential security issues with storing per-user files to a shared directory. I'm now thinking about a new setting (mail_temp_dir?) for v2.0 where these temp files would be stored (lda, lmtp, some others in future). Maybe the b) problem...

...(2) Provides a convenience vfs_init_pseudo_fs_context() helper function for doing most of the work in mounting a pseudo filesystem. (3) Converts all the trivial filesystems that have no arguments to fs_context. (4) Converts binderfs (which was trivial before January). (5) Converts ramfs, tmpfs, rootfs and devtmpfs. (6) Kills off mount_pseudo(), mount_pseudo_xattr(), mount_ns(), sget_userns().

hpa notified me in private mail that we have an issue that when building initramfs - if the content changes (say kinit) then the initramfs will not be rebuild. The solution I have come up with is to let make check all the files included in the initramfs and rebuild it if any files are newer than the initramfs and also rebuild if arguments changes (root_uid). In same process the...

Has anyone ever mounted their /var/lib/mysql on a tmpfs or ramfs? Are there any performance gains to be made doing this? TIA

"to memory" means: mounting a ~2 GByte filesystem [ tmpfs?, or ramfs? ], and put the "/tmp" on it. [ e.g.: 4 GByte ram in the pc ]. what to write in the "/etc/fstab"? I would like to collect the [ answers too:P ]: Advantages: - Memory is way faster then HDD/SSD, so it could speed things up - "SSD amortization" is less Disadva...

I'm not sure when exactly this started, but currently when I specify a ramfs image via the initrd line in grub, kinit picks it up as an initrd and tries (and fails) to unpack it and run linuxrc from it. I'm assuming this is not the intended behavior. Can anyone point me into the proper direction for unpacking an initramfs image ontop of the in-kernel image? Currently...
