[Jailkit-users] ignore files during init?

[E.B.]

Hello, sorry if I am missing somethiing obvious,
but search of archives don't turn up much.  I want
to avoid copying certain files/dirs during jk_init

For example, I found that I would like to skip
/usr/share/vim/vimfiles/.netrwhist but otherwise
copy the other vim files.  

Is there an "ignore" directive for jk_init.ini?

Thank you.
