Debian Sid amd64, building packages for Linux From Scratch

checking whether mknod can create fifo without root privileges... configure: error: in `/media/usb mount directory/sources/coreutils':

configure: error: you should not run configure as root (set FORCE_UNSAFE_CONFIGURE=1 in environment to bypass this check)

then the configure script exits.

setting FORCE_UNSAFE_CONFIGURE to 1 gives the same result no matter how I set it.

running the script with no sudo or su -l results in security restrictions which do not allow me to configure even the first step:

./configure: line 4404: config.log: Permission denied

./configure: line 4414: config.log: Permission denied

chmod'ing everything in the directory will not do much since created files are always restricted to the user, if configure will even create those.
