Baselayout provides a basic set of files that are necessary for all systems to |
| 42 |
|
|
function properly, such as <path>/etc/hosts</path>. It also provides the basic |
| 43 |
|
|
filesystem layout used by Gentoo (i.e. <path>/etc</path>, <path>/var</path>, |
| 44 |
|
|
<path>/usr</path>, <path>/home</path> directories). |

OpenRC is a dependency-based rc system that works with whatever init is provided |
| 56 |
|
|
by the system, normally <path>/sbin/init</path>. However, it is <e>not</e> a |
| 57 |
|
|
replacement for <path>/sbin/init</path>. The default init used by Gentoo Linux |
| 58 |
|
|
is <c>sys-apps/sysvinit</c>, while Gentoo/FreeBSD uses the FreeBSD init provided |
| 59 |
|
|
by <c>sys-freebsd/freebsd-sbin</c>. |

Originally Gentoo's rc system was built into baselayout 1 and written entirely |
| 71 |
|
|
in bash. This led to several limitations. For example, certain system calls need |
| 72 |
|
|
to be accessed during boot and this required C-based callouts to be added. These |
| 73 |
|
|
callouts were each statically linked, causing the rc system to bloat over time. |
| 74 |
|
|
</p> |
| 75 |
|
|
|
| 76 |
|
|
<p> |
| 77 |
|
|
Additionally, as Gentoo expanded to other platforms like |
| 78 |
|
|
Gentoo/FreeBSD and Gentoo Embedded, it became impossible to require a bash-based |
| 79 |
|
|
rc system. This led to a development of baselayout 2, which is written in |
| 80 |
|
|
C and only requires a POSIX-compliant shell. During the development of |
| 81 |
|
|
baselayout 2, it was determined that it was a better fit if baselayout merely |
| 82 |
|
|
provided the base files and filesystem layout for Gentoo and the rc system |
| 83 |
|
|
was broken off into its own package. Thus we have OpenRC. |

OpenRC is primarily developed by <uri link="http://roy.marples.name/openrc">Roy |
| 88 |
|
|
Marples</uri> and supports all current Gentoo variations (i.e. Gentoo Linux, |
| 89 |
|
|
Gentoo/FreeBSD, Gentoo Embedded, and Gentoo Vserver) and other platforms such as |
| 90 |
|
|
FreeBSD and NetBSD. |

Migration to OpenRC is fairly straightforward; it will be pulled in as part of |
| 103 |
|
|
your regular upgrade process by your package manager. The most important step |
| 104 |
|
|
actually comes after you install the new <c>>=sys-apps/baselayout-2</c> and |
| 105 |
|
|
<c>sys-apps/openrc</c> packages. It is <e>critical</e> that you run |
| 106 |
|
|
<c>dispatch-conf</c> and ensure your <path>/etc</path> is up to date before |
| 107 |
|
|
rebooting. <brite>Failure to do so will result in an unbootable system</brite> |
| 108 |
|
|
and will require the use of the Gentoo LiveCD to perform the steps below to |
| 109 |
|
|
repair your system. |

| 111 |
|
|
|
| 112 |
|
|
<p> |
| 113 |

|
Once you've finished updating your config files, there are a few things to |
| 114 |
nightmorph |
1.4 |
verify prior to rebooting. |

<path>/etc/rc.conf</path>. Please read through <path>/etc/rc.conf</path> and |
| 127 |
|
|
<path>/etc/conf.d/rc</path> and migrate the settings. Once you are complete, |
| 128 |

Normally, when you want certain kernel modules automatically loaded at boot, you |
| 139 |
|
|
place them into <path>/etc/modules.autoload.d/kernel-2.6</path> along with any |
| 140 |
|
|
parameters you wanted to pass to them. In baselayout-2, this file is not used |
| 141 |
|
|
anymore. Instead, autoloaded modules and module parameters are placed in one |
| 142 |
|
|
file, <path>/etc/conf.d/modules</path>, no matter the kernel version. |
| 143 |
|
|
</p> |
| 144 |
|
|
|
| 145 |
|
|
<p> |
| 146 |
|
|
An example old style configuration would be: |
| 147 |
|
|
</p> |
| 148 |
|
|
|
| 149 |
|
|
<pre caption="/etc/modules.autoload.d/kernel-2.6"> |

cx88_dvb video_br=2 |
| 152 |
|
|
</pre> |
| 153 |
|
|
|
| 154 |
|
|
<p> |
| 155 |
|
|
Converting the above example would result in the following: |
| 156 |
|
|

| 164 |
|
|
|
| 165 |
|
|
<p> |
| 166 |
|
|
In the above examples, the modules and their parameters would only be passed |
| 167 |
|
|
to 2.6.x series kernels. The new configuration allows for fine grained |
| 168 |
|
|
control over the modules and parameters based on kernel version. |

The <c>boot</c> runlevel performs several important steps for every machine. For |
| 210 |
|
|
example, making sure your root filesystem is mounted read/write, that your |
| 211 |
|
|
filesystems are checked for errors, that your mountpoints are available, and |
| 212 |
|
|
that the <path>/proc</path> pseudo-filesystem is started at boot. |

With OpenRC, volume management services for your block storage devices are no |
| 217 |
|
|
longer run automatically at boot. This includes lvm, raid, swap, device-mapper |
| 218 |
|
|
(dm), dm-crypt, evms, and the like. You must ensure the appropriate initscript |
| 219 |
|
|
for these services is in the <c>boot</c> runlevel, otherwise it's possible that |
| 220 |
|
|
your system will not boot! |

While the OpenRC ebuild will attempt to do this migration for you, you should |
| 225 |
nightmorph |

verify that it migrated all the volume management services properly: |

Clock settings have been renamed from <path>/etc/conf.d/clock</path> to your |
| 335 |
|
|
system's native tool for adjusting the clock. This means on Linux it will be |
| 336 |
|
|
<path>/etc/conf.d/hwclock</path> and on FreeBSD it will be |
| 337 |
nightmorph |
1.16 |
<path>/etc/conf.d/adjkerntz</path>. Systems without a working real time clock |
| 338 |
|
|
(RTC) chip should use <path>/etc/init.d/swclock</path>, which sets the system |
| 339 |
|
|
time based on the mtime of a file which is created at system shutdown. The |
| 340 |
|
|
initscripts in <path>/etc/init.d/</path> have also been renamed accordingly, so |
| 341 |
|
|
make sure the appropriate script for your system has been added to the boot |
| 342 |
nightmorph |

runlevel. |

|
Additionally, the <c>TIMEZONE</c> variable is no longer in this file. Its |
| 347 |
vapier |
1.8 |
contents are instead found in the <path>/etc/timezone</path> file. If it |
| 348 |
|
|
doesn't exist, you will of course have to create it with your timezone. Please |
| 349 |
|
|
review both of these files to ensure their correctness. |

The proper value for this file is the path relative to your timezone from |

<path>/usr/share/zoneinfo</path>. For example, for someone living on the east |

coast of the United States, the following would be a correct setting: |

Previously, you could log the boot process by using |
| 417 |
|
|
<c>app-admin/showconsole</c>. However, OpenRC now handles all logging |
| 418 |
|
|
internally, so there's no need for the hacks that <c>showconsole</c> employed. |
| 419 |
|
|
You can safely unmerge <c>showconsole</c>. To continue logging boot messages, |
| 420 |
|
|
just set the appropriate variable in <path>/etc/rc.conf</path>. Logs will appear |
| 421 |
|
|
in <path>/var/log/rc.log</path>. |

In the early versions of OpenRC, we explictly detected multiple types of |
| 449 |
|
|
virtualization, and used that detection to note when certain init scripts |
| 450 |
|
|
should be skipped, using the <b>keyword</b> call in the <b>depend</b> |
| 451 |
|
|
functions. |
| 452 |
|
|
</p> |
| 453 |
|
|
|
| 454 |
|
|
<p> |
| 455 |
|
|
However, as of the 0.7.0 release, you are required to explicitly configure the |
| 456 |
robbat2 |
1.25 |
sub-type using the <b>rc_sys</b> variable in <path>/etc/rc.conf</path>. The |
| 457 |
|
|
sub-type should be set to match the virtualization environment that the given |
| 458 |
|
|
root is in. In general, the non-empty <b>rc_sys</b> value should be within the |
| 459 |
|
|
virtual containers; The host node will have <b>rc_sys=""</b>. |
| 460 |
robbat2 |
1.23 |
</p> |
| 461 |
|
|
|
| 462 |
|
|
<impo> |
| 463 |
|
|
If you do not have any specific sub-type, please use the default of an empty |
| 464 |
|
|
string <b>""</b>. If the variable is unset, you will be given a warning and we |
| 465 |
|
|
will attempt to use the old detection algorithm. |

robbat2 |
1.26 |
<note> |
| 469 |
|
|
If you do not know what value your system was using with the automatic |
| 470 |
|
|
detection, you should temporarily comment out the <b>rc_sys</b> variable and |
| 471 |
|
|
run the detection command, <c>rc -S</c>. |

The detection algorithm had to be replaced with manual configuration due to |
| 480 |
robbat2 |
1.23 |
the introduction of new sub-types and changes to the kernel that made prior |

Once you've finished updating your config files and initscripts, the last thing |
| 540 |
|
|
to do is <b>reboot</b>. This is necessary because system state information is |
| 541 |
|
|
not preserved during the upgrade, so you'll need to provide it with a fresh |
| 542 |
|
|
boot. |

Previously it was possible to temporarily stop a service without taking down all |
| 557 |
|
|
the depending services by using <c>/etc/init.d/service pause</c>. In OpenRC, the |
| 558 |
|
|
<c>pause</c> action was removed; this functionality is supported by the |
| 559 |
|
|
<c>/etc/init.d/service --nodeps stop</c>, which also works in the old |
| 560 |
|
|
baselayout. |

Previously, the initial <b>rootfs</b> entry was removed from |
| 571 |
|
|
<path>/etc/mtab</path>, and only the real root <path>/</path> entry was |
| 572 |
nightmorph |
1.28 |
present. The duplicate rootfs item was actually added back during shutdown. |
| 573 |
robbat2 |
1.27 |
In OpenRC, both entries must be present for full support of initramfs and |
| 574 |
|
|
tmpfs-on-root. This also means that less writing is required during shutdown. |
