 * teach parse_timestamp() timezones like the calendar spec already knows it
 
-* beef up s2h to implement a battery watch loop: instead of entering
-  hibernation unconditionally after coming back from resume make a decision
-  based on the battery load level: if battery level is above a specific
-  threshold, go to suspend again, only hibernate if below it. This means we'd
-  stick to suspend usually, but fall back to hibernation only when battery runs
-  empty (well, subject to our sampling interval). Related to this, check if we
-  can make ACPI _BTP (i.e. /sys/class/power_supply/*/alarm) work for us too,
-  i.e. see if it can wake up machines from suspend, so that we could resume
-  automatically when the system is low on power and move automatically to
-  hibernation mode. (see

-  section 10.2.2.8 and

 * We should probably replace /etc/rc.d/README with a symlink to doc
   content. After all it is constant vendor data.
