Hi Michael, https://bugs.gentoo.org/941878 seems to be the relevant bug with discussion on why it was changed. > PS. Also I do not understand the meaning of these notations: > > IUSE="foo" Everything outside the quotes is normal bash syntax, the variable contents are interpreted by Portage. This sets the ebuild to have USE flags "foo". (If IUSE was set before this line, it will clear out all the USE flags that were defined before.) > IUSE="+foo" This sets the ebuild to have USE flags "foo", the preceding "+" on the USE flag means it is enabled by default. > IUSE+="foo" This appends to the previous IUSE value. Equivalent to IUSE="${IUSE}foo" (note the missing space, hence why the Firefox ebuild uses IUSE+=" foo" instead). Cheers, Marco
