So Pids asked me to write a how-to for booting Kermacs with Lilo. I figured since it's lunchtime, i'm gonna write it. This can be applied to Szalonna as well.

Requirements:

1. Latest Kermacs rev (1126)
2. Your own kernel / debian kernel / whatever kernel as long as it works.
3. Initrd of your choice (My long-time favorite: https://bitbucket.org/piotrkarbowski/better-initramfs)
4. Lilo sources (24.2 at this time of writing) -> https://lilo.alioth.debian.org/ftp/sour ... 4.2.tar.gz
5. A usb flashdrive

The How-tos:

1. Extract kermacs to your flashdrive
Code: Select all
```
 
# mount /dev/sdX /tmp/kermacs 
# cp linuxbbq-kermacs-1126.txz /tmp/kermacs 
# cd /tmp/kermacs && tar xpvf linuxbbq-kermacs-1126.txz
```
2. Install LILO to your flashdrive, i like to compile it statically
Code: Select all
```
$ cd $lilo-source-dir
# make alles
# make DESTDIR=/tmp/kermacs install

###### remove the bloats ########
# rm -rf /tmp/kermacs/etc/initramfs /tmp/kermacs/etc/kernel 
```
3. Now that you have lilo installed to your flash-drive, move your kernel to its designated place in /tmp/kermacs/boot.

For example, i use towo/siduction's latest 4.3 kernel. So i just have to copy /boot/vmlinuz-4.3.0-towo.3-siduction-686-pae to /tmp/kermacs/boot, don't forget the initrd. Also copy the /lib/modules/$kernel-version directory to /tmp/kermacs/lib/modules/$kernel-version. If you're (like me) testing kermacs on a relatively new hardware: Z-170 Skylake which isn't supported by 3.xx kernel. The shipped kernel worked super fine with other hardware configuration. For an instruction of using the shipped kernel, take a look at Pidsley's post.

4. Symlink the kernel and initrd to the root (/) of kermacs. 'ls -l' should give you an idea what to symlink.

5. Write lilo.conf to /tmp/kermacs/etc/lilo.conf
Code: Select all
```
boot=/dev/sdX

default=Kermacs
timeout=50
lba32 
prompt
compact

# Kermacs entry
  image=/boot/vmlinuz-4.3.0-towo.3-siduction-686-pae
  initrd=/boot/initrd.img-4.3.0-towo.3-siduction-686-pae
  append="init=/linuxrc rootfstype=ext4"
  root=/dev/sdX1
  read-only
  label=Kermacs
```
You can add debian.bmp to the lilo conf too (if that's your thing.)

5. Chroot to your kermacs, and run lilo
Code: Select all
```
# cd /tmp/kermacs
# for d in dev proc sys run; do mount --bind /$d $d; done
# chroot . /bin/bash
# /sbin/lilo.static 
```
6. Reboot to the usb, and enjoy it.

You can for instance replace lilo with syslinux/grub, but since i really like lilo i haven't tried other bootloader(s). Hmmm not really, i've tried UEFI booting before, and it worked. Just uhhh nobody seems to care about uefi right?

EDIT_1: adding syslinux/grub part
EDIT_2: Fix typo

Yay! Thanks for the write-up, frank.

If you just want to use the kernel that is included with Kermacs, you can skip steps 3 and 4, and change the lilo.conf as follows:

Code: Select all

boot=/dev/sdX

default=Kermacs
timeout=50
lba32
prompt
compact

# Kermacs entry
  image=/vmlinuz
  initrd=/initrd.img
  append="init=/linuxrc rootfstype=ext4"
  root=/dev/sdX1
  read-only
  label=Kermacs

^ Yup, and thank you once again for such a cool release.
