G10h4ck:

I have been fiddling with crontab and discovered that by default OpenWrt doesn't support special times ( @reboot @hourly... ) in crontab, investigating in the config I found this BUSYBOX_DEFAULT_FEATURE_CROND_SPECIAL_TIMES that is set to n by default, but I could not find how to change the config value (not the default)

OpenWrt v18.06.1

To reproduce run make meuconfig, press /, and search for CROND_SPECIAL_TIMES you can see that the symbol BUSYBOX_DEFAULT_FEATURE_CROND_SPECIAL_TIMES exists and it is defined to be n (note the DEFAULT in the name), as this is a default value there is no way to change it, moreover if you look for an option to enable crond special times you cannot find it, again run make menuconfig go to Base System -> busybox -> Miscellaneous Utilities -> crond, you can see other options to be changed but not this one.

How can this be fixed?
And what I can do as workaround in the meantime?
