The openntmpfiles package is designed so that it can be used on systems independently of whether openrc is used.

# OpenRC NEWS
|
|
|
|
This file will contain a list of notable changes for each release. Note
|
|
the information in this file is in reverse order.
|
|
|
|
## OpenRC-0.23
|
|
|
|
The tmpfiles.d processing code, which was part of previous versions of
|
|
OpenRC, has been separated into its own package [1]. If you need to
|
|
process systemd style tmpfiles.d files, please install this package.
|
|
|

|
|
|
|
## OpenRC-0.22
|
|
|
|
In previous versions of OpenRC, configuration information was processed
|
|
so that service-specific configuration stored in /etc/conf.d/* was
|
|
overridden by global configuration stored in /etc/rc.conf. This release
|
|
reverses that. Global configuration is now overridden by
|
|
service-specific configuration.
|
|
|
|
The swapfiles service, which was basically a copy of the swap service,
|
|
has been removed. If you are only using swap partitions, this change
|
|
will not affect you. If you are using swap files, please adjust the
|
|
dependencies of the swap service as shown in /etc/conf.d/swap.
|
|
|
|
## OpenRC-0.21
|
|
|
|
This version adds a daemon supervisor which can start daemons and
|
|
restart them if they crash. See supervise-daemon-guide.md in the
|
|
distribution for details on its use.
|
|
|
|
It is now possible to mark certain mount points as critical. If these
|
|
mount points are unable to be mounted, localmount or netmount will fail.
|
|
This is handled in /etc/conf.d/localmount and /etc/conf.d/netmount. See
|
|
these files for the setup.
|
|
|
|
The deprecation messages in 0.13.x for runscript and rc are now
|
|
made visible in preparation for the removal of these binaries in 1.0.
|
|
|
|
The steps you should take to get rid of these warnings is to run openrc
|
|
in initialization steps instead of rc and change the shebang lines in
|
|
service scripts to refer to "openrc-run" instead of "runscript".
|
|
|
|
In 0.21.4, a modules-load service was added. This works like the
|
|
equivalent service in systemd. It looks for files named *.conf first in
|
|
/usr/lib/modules-load.d, then /run/modules-load.d, then
|
|
/etc/modules-load.d. These files contain a list of modules, one per
|
|
line, which should be loaded into the kernel. If a file name appears in
|
|
/run/modules-load.d, it overrides a file of the same name in
|
|
/usr/lib/modules-load.d. A file appearing in /etc/modules-load.d
|
|
overrides a file of the same name in both previous directories.
|
|
|
|
## OpenRC-0.19
|
|
|
|
This version adds a net-online service. By default, this
|
|
service will check all known network interfaces for a configured
|
|
interface or a carrier. It will register as started only when all
|
|
interfaces are configured and there is at least a carrier on one
|
|
interface. The behaviour of this service can be modified in
|
|
/etc/conf.d/net-online.
|
|
|
|
Currently, this only works on Linux, but if anyone wants to port to
|
|
*bsd, that would be welcomed.
|
|
|
|
## OpenRC-0.18.3
|
|
|
|
Modern Linux systems expect /etc/mtab to be a symbolic link to
|
|
/proc/self/mounts. Reasons for this change include support for mount
|
|
namespaces, which will not work if /etc/mtab is a file.
|
|
By default, the mtab service enforces this on each reboot.
|
|
|
|
If you find that this breaks your system in some way, please do the
|
|
following:
|
|
|
|
- Set mtab_is_file=yes in /etc/conf.d/mtab.
|
|
|
|
- Restart mtab. This will recreate the /etc/mtab file.
|
|
|
|
- Check for an issue on https://github.com/openrc/openrc/issues
|
|
explaining why you need /etc/mtab to be a file. If there isn't one,
|
|
please open one and explain in detail why you need this to be a file.
|
|
If there is one, please add your comments to it. Please give concrete
|
|
examples of why it is important that /etc/mtab be a file instead of a
|
|
symbolic link. Those comments will be taken into consideration for how
|
|
long to keep supporting mtab as a file or when the support can be
|
|
removed.
|
|
|
|
## OpenRC-0.18
|
|
|
|
The behaviour of localmount and netmount in this version is changing. In
|
|
the past, these services always started successfully. In this version,
|
|
they will be able to fail if file systems they mount fail to mount. If
|
|
you have file systems listed in fstab which should not be mounted at
|
|
boot time, make sure to add noauto to the mount options. If you have
|
|
file systems that you want to attempt to mount at boot time but failure
|
|
should be allowed, add nofail to the mount options for these file
|
|
systems in fstab.
|
|
|
|
## OpenRC-0.14
|
|
|
|
The binfmt service, which registers misc binary formats with the Linux
|
|
kernel, has been separated from the procfs service. This service will be
|
|
automatically added to the boot runlevel for new Linux installs. When
|
|
you upgrade, you will need to use rc-update to add it to your boot
|
|
runlevel.
|
|
|
|
The procfs service no longer automounts the deprecated usbfs and
|
|
usbdevfs file systems. Nothing should be using usbdevfs any longer, and
|
|
if you still need usbfs it can be added to fstab.
|
|
|
|
Related to the above change, the procfs service no longer attempts to
|
|
modprobe the usbcore module. If your device manager does not load it,
|
|
you will need to configure the modules service to do so.
|
|
|
|
The override order of binfmt.d and tmpfiles.d directories has been
|
|
changed to match systemd. Files in /run/binfmt.d and /run/tmpfiles.d
|
|
override their /usr/lib counterparts, and files in the /etc counterparts
|
|
override both /usr/lib and /run.
|
|
|
|
## OpenRC-0.13.2
|
|
|
|
A chroot variable has been added to the service script variables.
|
|
This fixes the support for running a service in a chroot.
|
|
This is documented in man 8 openrc-run.
|
|
|
|
The netmount service now mounts nfs file systems.
|
|
This change was made to correct a fix for an earlier bug.
|
|
|
|
## OpenRC-0.13
|
|
|
|
/sbin/rc was renamed to /sbin/openrc and /sbin/runscript was renamed to
|
|
/sbin/openrc-run due to naming conflicts with other software.
|
|
|
|
Backward compatible symbolic links are currently in place so your
|
|
system will keep working if you are using the old names; however, it is
|
|
strongly advised that you migrate to the new names because the symbolic
|
|
links will be removed in the future.
|
|
Warnings have been added to assist with this migration; however, due to the
|
|
level of noise they produce, they only appear in verbose mode in this release.
|
|
|
|
The devfs script now handles the initial mounting and setup of the
|
|
/dev directory. If /dev has already been mounted by the kernel or an
|
|
initramfs, devfs will remount /dev with the correct mount options
|
|
instead of mounting a second /dev over the existing mount point.
|
|
|
|
It attempts to mount /dev from fstab first if an entry exists there. If
|
|
it doesn't it attempts to mount devtmpfs if it is configured in the
|
|
kernel. If not, it attempts to mount tmpfs.
|
|
If none of these is available, an error message is displayed and static
|
|
/dev is assumed.
|
|
|
|
## OpenRC-0.12
|
|
|
|
The net.* scripts, originally from Gentoo Linux, have
|
|
been removed. If you need these scripts, look for a package called
|
|
netifrc, which is maintained by them.
|
