1 2BACKWARD COMPATIBILITY ISSUES FOR HEYU VERSION 2 3 4Configuration file 5------------------ 6Heyu version 2 can use an existing Heyu configuration file 7from version 1 (~/.x10config or /etc/x10.conf) provided 8it is renamed and moved to the new location where Heyu 9version 2 expects to find it - either "~/.heyu/x10config" 10or "/etc/heyu/x10.conf" (notice the 'dot' changes). 11There are a number of new configuration options for 12version 2 that the user may then want to add, which are 13explained in both the x10config.5 man page and in the 14example file "x10config.sample" provided. Of course 15for some users it may be more convenient to simply rename 16and modify the "x10config.sample" file. 17 18In operation, Heyu version 2 must write some files in 19the same directory as the configuration file, so this 20directory must be writeable. 21 22Schedule file 23------------- 24In most cases an existing schedule file used for Heyu 25version 1 will work in version 2, however dawn/dusk 26related events are now handled directly by the Heyu 27program and the old 'makesched' utility is no longer 28used. The default name for the schedule file is now 29x10.sched and Heyu version 2 will expect to find it 30in the same directory as the configuration file. 31(Its name can be changed via the configuration file.) 32 33Under Heyu version 2, the CM11A clock is maintained 34on Local Standard Time throughout the year. Events 35in the schedule file are assumed to be Local Civil 36Time (i.e., Wall Clock Time) and Heyu automatically 37adjusts them during periods of Daylight Saving Time. 38Heyu version 2 automatically sets the CM11A clock 39to the correct time (derived from the system clock) 40when a schedule is uploaded or when the 'heyu setclock' 41command is executed. 42 43 44Warning 45------- 46Users running a dual-boot system with MS-Windows 47should read the warning in the x10config.5 man page 48about running X10's ActiveHome software while booted 49into Windows if the CM11A has been programmed under 50Unix/Linux by Heyu with certain configuration options. 51 52 53 54
