Subject: RTC wakealarm write-only, still has 644 permissions

...should they be changed to 200? Or perhaps file should be readable?

root@amd:/sys/class/rtc/rtc0# cat wakealarm 
root@amd:/sys/class/rtc/rtc0# echo 132719 > wakealarm 
root@amd:/sys/class/rtc/rtc0# ls -al wakealarm 
-rw-r--r-- 1 root root 0 Sep 20 12:30 wakealarm
root@amd:/sys/class/rtc/rtc0# cat wakealarm 
root@amd:/sys/class/rtc/rtc0# cat wakealarm 
root@amd:/sys/class/rtc/rtc0# 


...standard PC with reasonably recent kernel...
