Enabling and disabling system services in the default runlevel
is also distro-specific, and some distro's may require some minor
boot-time
initialization tasks.
A directive is included in /etc/sysimage.conf to specify
the distribution of the master image to enable oneSIS to handle
these tasks for different distributions. If the specified
distribution is not currently supported, it may be necessary to
create a distribution patch as mentioned in section
4.6.
oneSIS will operate even on an unsupported distribution, but
some of the distro-specific features described above will not be
available. Remember that any SERVICE directives in the
/etc/sysimage.conf file must always be enabled in the default
runlevel. The rest of the system will still work as expected.
