SYNOPSIS
seconds]
DESCRIPTION
saves data, flagged as persistent in the core kernel KRS tree, to files
on disk. These files are read when the system is booted, in order to
restore the aforementioned persistent data.
When running in daemon mode, sleeps, waking periodically to check if
any persistent data have changed since the last save. If persistent
data have changed, the new state of the data is saved to disk. Other‐
wise, sleeps for another period of time and then repeats the process.
When running in one time (non-daemon) mode, unconditionally saves per‐
sistent data to disk and then exits.
Normally, is executed in daemon mode by init(1M). The entry for will
cause to be respawned automatically if it is terminated.
uses the message logging facility to log all activity.
Persistent KRS data are maintained in files based on the class of the
data in question. Currently, the following classes are recognized:
Data that apply to the system in general,
regardless of what configuration is booted. This data is
saved in the file
Data specific to a given bootable configuration.
This data is saved in the file
only saves the class; the class is managed by the kernel configuration
tools (see kconfig(5)).
Options
recognizes the following options:
One time mode, unconditionally save persistent data to disk, then
exit.
Run from parent does not spawn a child nor exit. Required if from
inittab is to work properly.
Set the delay time to
seconds seconds. This is the time interval between
attempted saves of persistent data. The default interval
is 300 seconds.
