# Livenetsquash dracut module

This module allows to boot live linux system from squashed image that downloaded from http-server.

## Module installation

```

cd /tmp

curl -OL https://github.com/kvaps/livenetsquash/archive/master.tar.gz

tar xvf master.tar.gz

mv livenetsquash-master/dracut/* /usr/lib/dracut/modules.d/

rm -rf livenetsquash-master master.tar.gz

vim /etc/dracut.conf

```

add modules:

```

dracutmodules+="network base livenetsquash overlay-root"

```

generate initrd image:

```

dracut -f /boot/initramfs -v

```

## Squashed image

Build squashed image, example:

```

mksquashfs  rootfs.squash -noappend

```

I advise you to use [darkhttpd](https://github.com/ryanmjacobs/darkhttpd) as simple http server for store your squased image.

## Bootloader configuration

Example `pxelinux.cfg/default`

```

default centos7

ontimeout centos7

label centos7

    kernel vmlinuz

    append initrd=initramfs selinux=0 root=live:http://boot-server/rootfs.squash rootovl=1 ro rd.live.image

```

Example `grub.cfg` (support efi and http-method)

```

set timeout=3

menuentry 'Linux diskless' --class os {

     insmod efi_gop

     insmod efi_uga

     set net_default_server=${pxe_default_server}

     echo "Loading Linux from http://${net_default_server}/vmlinz ..."

     linux (http)/vmlinuz root=live:http://${pxe_default_server}/rootfs.squash rootovl=1 ro rd.live.image

     echo "Loading initial ramdisk from http://${pxe_default_server}/initramfs ..."

     initrd (http)/initramfs

}

```
