# Delivery of custom `driver.conf` files

To deliver a custom `driver.conf(4)` file without rebuilding the PI, place the
required file and its hash file in the per-CN boot file system directory.

```
cd /tftpboot/bootfs/90<lower-case-mac-with-no-colons>/
mkdir -p kernel/drv
cp /.../sd.conf kernel/drv
digest -a sha1 kernel/drv/sd.conf > kernel/drv/sd.conf.hash
```

Note that this customization will be lost the next time that the booter instance
is redeployed.
