Running it may trigger firmware bugs and make your system unusable without using some special hardware to reprogram the firmware. Now, as the root user: make install LIBDIR=/usr/lib BINDIR=/bin Move the shared libraries to /lib, and recreate the symlinks in /usr/lib: mv /usr/lib/libefi{boot,var}.so.* /lib && ln -sfv ../../lib/$(readlink /usr/lib/libefiboot.so) /usr/lib/libefiboot.so && ln -sfv ../../lib/$(readlink /usr/lib/libefivar.so) /usr/lib/libefivar.so CFLAGS="-O2 -Wno-stringop-truncation": This option overrides the compiler flags defaulted by this package, to avoid build failure. LIBDIR=/usr/lib: This option overrides the default library directory of the package (/usr/lib64, which is not used by LFS.) BINDIR=/bin: Make efivar avaliable even if /usr is offline.
