Hi, We are looking at situations with OLPC XO laptops where all RTC power has been lost and hence the system has lost its time/date and RTC contents are invalid. The usual thing to do in this case is to reset the system time to the current moment and then use hwclock to save it to the RTC. However, this is proving quite confusing. # hwclock --systohc hwclock: select() to /dev/rtc0 to wait for clock tick timed out: No such file or directory Firstly, the corresponding warn() in hwclock-rtc.c should be warnx() so that it does not print the errno message. When select returns 0 (timeout), interpreting errno does not make sense. Secondly, did that hwclock command fail or succeed? Our users and a developer saw that output and concluded "hwclock is broken" and filed a bug. Having seen the bug report, I drew the same conclusion. Only upon testing further I realised that this is only a warning and hwclock did go on and set the RTC time appropriately. So, can this message be silenced completely, or can we add a "RTC successfully set from system clock" success message that appears afterwards? Let me know if there is a preference, then I'll go and send a patch.
