For example,
service recovery /sbin/recovery
onrestart start loadkeys
onrestart class_start con
onrestart stop recovery
Previously, if you had a service like the above, the "onrestart stop
recovery" clause would not have any effect, because the restart flag
would be re-set after the stop command had executed.
This is similar to a service with the "oneshot" keyword, with the critical
difference being that it executes the other onrestart commands when the
service dies.
LOG_UEVENTS is a boolean value as defined in system/core/init/init.h.
Therefore, code should use an #if check and not an #ifdef check as the
macro will always be defined.
To add arguments dynamically to a service, start the service like so:
setprop ctl.start service_to_run:arg1 arg2 arg3...
To start a service with *no* dynamic arguments, start the service normally:
setprop ctl.start service_to_run
Dynamic arguments are only supported on 'oneshot' services

The 'args' array *must* be the last entry in the structure.
This fixes a longstanding issue (apparently since tc3) where
a service with an argument would corrupt the heap. The more
arguments, the more corruption :|. This will probably also end up
making key-code bound services more reliable (ie: bugreports triggered
via the keyboard)

In keeping with the pattern of mtd@partition, I have added loop@path as a way to specify a loopback device. This way you can do things like mount directories in /system using cramfs from a file otherwise on /system (just one example oof how I'm using it). I specifically went with loop@ rather than adding this feature as a flag as the flags system is designed to set bits in the flags argument to mount: using loop@ fit the model in a much simpler manner and actually feels "correct".
This is a better version of the previously submitted 4045 that also refactors the mtd@ case. The reason for this is that I received comments that I should check for errors and return errors rather that do work in the case of success and fall through, but the mtd@ case wasn't doing that either and it became awkward to design the function so that it was half in one style of error handling and half in another. I also made certain to use inequality comparisons for Unix's -1 error returns rather than checking for -1, refactored my large if statement so as not to have danling parentheses, and disassocited the loop device on mount failure.
