+<title>System sub-types: Virtualization special cases</title> |
| 36 |
+<body> |
| 37 |
+ |
| 38 |
+<p> |
| 39 |
+In the early versions of OpenRC, we explictly detected multiple types of |
| 40 |
+virtualization, and used that detection to note when certain init scripts |
| 41 |
+should be skipped, using the <b>keyword</b> call in the <b>depend</b> |
| 42 |
+functions. |
| 43 |
+</p> |
| 44 |
+ |
| 45 |
+<p> |
| 46 |
+However, as of the 0.7.0 release, you are required to explicitly configure the |
| 47 |
+sub-type using the <b>rc_sys</b> variable in <path>/etc/rc.conf</path>. |
| 48 |
+</p> |
| 49 |
+ |
| 50 |
+<impo> |
| 51 |
+If you do not have any specific sub-type, please use the default of an empty |
| 52 |
+string <b>""</b>. If the variable is unset, you will be given a warning and we |
| 53 |
+will attempt to use the old detection algorithm. |
| 54 |
+</impo> |
| 55 |
+ |
| 56 |
+<pre caption="Setting system sub-type to none in /etc/rc.conf"> |
| 57 |
+rc_sys="" |
| 58 |
+</pre> |
| 59 |
+ |
| 60 |
+<p>The detection algorithm had to be replaced with manual configuration due to |
| 61 |
+the introduction of new sub-types and changes to the kernel that made prior |
| 62 |
+detection unreliable.</p> |
