[gentoo-user] emerge --resume question

[Peter Campion-Bye]

Hi,
Trying to do an 'emerge -e world' I come up against the odd package that
doesn't build without some intervention. I know I can do 'emerge --resume
--skipfirst' and carry on, but sometimes the broken package could be built ok
with a little intervention, for example, my build breaks on pilot-link, which
can be simply fixed with 'FEATURES="-sandbox" emerge pilot-link'. Problem is,
I can't do a resume after this as the emerge list from the world build has
been blatted when I emerged pilot-link. So, is there any way I can preserve
the state of the world build, so that after building the breaking package I
can do a --resume --skipfirst and carry on with the world build?
Any other suggestions for workarounds?
thanks
