Dear systemd folks,
Debian uses a shell script as `/init` in initrd, and I like to extend
that, to set the time stamps for the initrd execution.
`systemd-analyze` built from `src/analyze/analyze.c` uses D-Bus to get
the time stamp to display that.
```
bus_get_uint64_property(bus,
"/org/freedesktop/systemd1",
"org.freedesktop.systemd1.Manager",
"InitRDTimestampMonotonic",
×.initrd_time) < 0
```
In `src/core/manager.c` the value is set like below.
```
if
(dual_timestamp_is_set(&m->timestamps[MANAGER_TIMESTAMP_INITRD])) {
/* The initrd case on bare-metal*/
kernel_usec =
m->timestamps[MANAGER_TIMESTAMP_INITRD].monotonic -
m->timestamps[MANAGER_TIMESTAMP_KERNEL].monotonic;
initrd_usec =
m->timestamps[MANAGER_TIMESTAMP_USERSPACE].monotonic -
m->timestamps[MANAGER_TIMESTAMP_INITRD].monotonic;
log_struct(LOG_INFO,
"MESSAGE_ID="
SD_MESSAGE_STARTUP_FINISHED_STR,
"KERNEL_USEC="USEC_FMT, kernel_usec,
"INITRD_USEC="USEC_FMT, initrd_usec,
"USERSPACE_USEC="USEC_FMT,
userspace_usec,
LOG_MESSAGE("Startup finished in
%s%s (kernel) + %s (initrd) + %s (userspace) = %s.",
buf,
format_timespan(kernel,
sizeof(kernel), kernel_usec, USEC_PER_MSEC),
format_timespan(initrd,
sizeof(initrd), initrd_usec, USEC_PER_MSEC),
format_timespan(userspace, sizeof(userspace), userspace_usec,
USEC_PER_MSEC),
format_timespan(sum,
sizeof(sum), total_usec, USEC_PER_MSEC)));
```
Is it possible to set that value from a shell script? If yes, could you
please tell me how?
Kind regards,
Paul
