Hi all, Several of our eclasses use a mechanism that prevents them from being inherited more than once. Some eclasses test for a special value [1]:
___ECLASS_ONCE_EUTILS="recur -_+^+_- spank" while others simply assign 1 and test for a non-empty variable [2]: _GIT_R3=1 The problem with the name of the former variable is that function and variable names starting with __ (two underscores) are reserved for package manager use [3], so the variable should be renamed. We can take this as an occasion to standardise the variable's name and value. Since names like _USER or _PAM look a little dangerous, I suggest _<eclassname>_ECLASS for the variable's name. I have no strong preference for the variable's value. Is testing for a non-empty value sufficient? Then we should assign something simple (like "1"). If not, any string that is sufficiently random (like the one used in eutils) should be good.
