### Start services

Currently the following services provided by BusyBox or dropbearmulti are available. They are inactive by default, so use the bootparameters specified to enable them:
35+
36+
* SSHD `sshd=1` - you might want to add a permanent key to `/etc/dropbear`
37+
* HTTPD `httpd=1` - searches for files in `/srv/www`
38+
* TFTPD `tftpd=1` - serves files from `/srv/tftp`
39+
* UDHCPD `udhcpd=1` - starts only in `/etc/udhcpd.conf` is present

Those together are enough to build a PXE boot server. I also will add some build scripts to further expand the system for some rescue and forensic purposes:
