### stuff begins here
test -f build/chroot || mkdir -p build/chroot

###fakeroot -s build/fakechroot.save fakechroot debootstrap --variant=fakechroot bullseye build/chroot/ http://ftp.de.debian.org/debian
###fakechroot fakeroot debootstrap bullseye build/chroot/ http://ftp.de.debian.org/debian

### i have the problem, that fakechroot will not work atm. in ubuntu 22.04 i get libc6 version mismatch errors. so we run it direct as root. not my favorite, but works for now.
