# Example: Burn Scripts

Another way to accomplish these types of customizations is to use <a href="Plugins.md">Plugins</a>, which are more capable and easier to understand.

## b0script
```sh
#!/bin/bash
#
# Script run after burn, in a --mount mode (running system and burned disk both accessible)
#
function do_b0script() {
    logtoboth "* Start b0script for host '$hostname'"
    [ "$SDMPT" == "" ] && echo "? SDMPT is undefined in do_b0script ; aborting" && return
    #
    # Copy to final location if related service already installed (or no service)
    # Copy to /etc/sdm/local-assets if service not yet installed (logwatch, apcupsd, chrony, etc)
    #
    # Logwatch
    #
    logtoboth "> Copy assets for 'logwatch'"
    rsync -a /rpi/etc/logwatch/ $SDMPT/etc/sdm/local-assets/logwatch
    #
    # apcupsd
    #
    logtoboth "> Copy assets for 'apcupsd'"
    mkdir -p $SDMPT/etc/sdm/local-assets/apcupsd
    cp /rpi/pisrv1/etc/apcupsd/apcupsd.conf $SDMPT/etc/sdm/local-assets/apcupsd
    #

    #
    logtoboth "> Copy assets for 'chronyd'"
    mkdir -p $SDMPT/etc/sdm/local-assets/chrony
    cp /rpi/pisrv1/etc/chrony/chrony.conf $SDMPT/etc/sdm/local-assets/chrony
    #
    # Other configuration stuff
    #
    logtoboth "> Copy other configuration assets"
    logtoboth "> ...to /etc/sdm/local-assets/config"

```
## b1script
