"do_schroot": exec schroot -p -c sid32 -q -- "`basename $0`" "$@" All programs I run are a symbolic link to that script, which figures out how it was called and then runs that command in the 32 bit schroot. I could change the paramaters there, but that still wouldnt help as I want to be able to run several schroot programs. Would it be better to define one schroot instance and get all programs to use that explicitly?
