Slackware as a Linux rescue environment: Difference between revisions

Revision as of 20:34, 16 July 2022

Download from one of the Slackware mirrors the kernel and initrd image, which Slackware uses for the installation:

https://mirrors.slackware.com/slackware/slackware64-15.0/kernels/huge.s/bzImage

https://mirrors.slackware.com/slackware/slackware64-15.0/isolinux/initrd.img

It is possible to use bzImage from a different Slackware version (e.g., -current), in this case the directory /lib/modules/X.X.X/ inside initrd.img must be upgraded to the same version (see next item for how to unpack initrd.img). This can be useful to support newer hardware.

Unpack initrd image (as root):

# mkdir dir
# cd dir
# xzcat ../initrd.img | cpio -di
# chroot .

Set a root password; exit chroot
Pack the modified initrd image: find . | cpio -o -H newc | xz -9fv -C crc32 > ../initrd.img
Install a Linux distribution (e.g., Debian) on the remote server
Put bzImage and initrd.img to /boot/rescue/ directory on the remote server
Overwrite the content of the file /boot/grub/grub.cfg with the following, mutatis mutandis:

set default=0
set timeout=5

search --set=root --no-floppy --label ROOT

menuentry "Rescue (Installation Media)" {
  linux  /boot/rescue/bzImage load_ramdisk=1 prompt_ramdisk=0 rw \
    printk.time=0 SLACK_KERNEL=huge.s \
    kbd=us nic=auto:eth0:static:198.51.100.85:26:198.51.100.65
  initrd /boot/rescue/initrd.img
}

Reboot, then run source /etc/profile
Install Slackware in the usual way
