Gentoo partitioned /usr/src linux is shared
 

Can you elaborate on how it'd be if Gentoo partitioned /usr/src linux is shared among other Linuxes installation side by side ?

Instead of asking the same question a second time, work on your description to make it understandable. I reported this question as a duplicate.

What are you trying to achieve? Gentoo has kernel sources there, what could any other distro possibly do with these?
