Full Discussion: change initramfs by hand?
Operating Systems Linux Debian change initramfs by hand? Post 302268390 by otheus on Monday 15th of December 2008 02:19:43 PM

The method I described works as of Linux 2.6.13 (or before FC3) If you are using an older version (uname -k) perhaps you have to create a filesystem. See "Manually building a custom initial RAM disk" at Linux initial RAM disk (initrd) overview.

Code:
$ mkdir /tmp/initrd.tmp ; cd /tmp/initrd.tmp
$ <extract>
$ du -sk . 
$ # use size reported above for: $blocks
$ dd if=/dev/zero of=/tmp/initrd.img bs=1024 count=$blocks
$ /sbin/mke2fs -F -m 0 -b 1024 /tmp/initrd.img $blocks
$ mount /tmp/initrd.img /mnt/initrd -t ext2 -o loop=/dev/loop0

If that works, copy the files from /tmp/initrd.tmp into /mnt/initrd. Afterwards:
Code:
$ umount /mnt/initrd
$ gzip /tmp/initrd.img

Now move it to /boot. Good luck!

initramfs on 2.4 kernel

Is there a patch available to support initramfs on the 2.4 kernel? We can't upgrade to 2.6 for legacy purposes. All I found on google were early references to how initramfs is better than the 2.4 initrd. Thanks much! (0 Replies)

plymouth-set-default-theme

PLYMOUTH-SET-DEFAU(1)						   User Commands					     PLYMOUTH-SET-DEFAU(1)

NAME

       plymouth-set-default-theme - Set the plymouth theme

SYNOPSIS

       plymouth-set-default-theme [OPTION...] [THEME]

DESCRIPTION

       When called with a THEME argument, the plymouth-set-default-theme command changes the preferred boot theme and also performs the necessary
       regeneration of the initial ramdisk (initrd) since plymouth is loaded from the boot loader from the initrd prior to the mounting of the
       root filesystem.

       If plymouth-set-default-theme is invoked with no options or parameters, it shows the currently selected theme by default. This output is
       used by the helper scripts plymouth-generate-initrd and plymouth-update-initrd to set the proper theme in the initial ramdisk.

OPTIONS

       The following options are understood:

       -h, --help
	   Show summary of options.

       -l, --list
	   List available themes.

       -r, --reset
	   Reset to default theme.

       -R, --rebuild-initrd
	   Rebuild initrd (necessary after changing theme).
