man returns execve: No such file or directory in chroot jail

I created a chroot jail and copied multiple binaries and their corresponding libraries to the relevant subdirectories. Example: cp -v /usr/bin/edit /home/jail/usr/bin ldd /usr/bin/edit linux-vdso.so.1 (0x00007fff565ae000) libm.so.6 => /lib64/libm.so.6 (0x00007f7749145000) libtinfo.so.5 => /lib64/libtinfo.so.5 (0x00007f7748f11000) libacl.so.1 => /lib64/libacl.so.1 (0x00007f7748d08000) libdl.so.2 => /lib64/libdl.so.2 (0x00007f7748b04000) libperl.so => /usr/lib/perl5/5.18.2/x86_64-linux-thread-multi/CORE/libperl.so (0x00007f7748771000) libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f7748554000) libc.so.6 => /lib64/libc.so.6 (0x00007f77481ad000) libattr.so.1 => /lib64/libattr.so.1 (0x00007f7747fa8000) /lib64/ld-linux-x86-64.so.2 (0x00007f7749446000) libcrypt.so.1 => /lib64/libcrypt.so.1 (0x00007f7747d6d000) cp -v /lib64/{libm.so.6,libtinfo.so.5,libacl.so.1,libdl.so.2,libpthread.so.0,libc.so.6,libattr.so.1,ld-linux-x86-64.so.2,libcrypt.so.1} /home/jail/lib64/ I did the same with the man command and copied all manual files with cp -rv /usr/share/man/ /home/jail/usr/share/, but if I execute it, it returns this error: -bash-4.2$ man gzip execve: No such file or directory What could be missing?

Man: 1 I compared the strace results of the jail and root user and they differ now only in this part (jail is left): As I added a bind mount to /var/run/nscd, the socket is available for the jail user: -bash-4.2$ if [[ -S /var/run/nscd/socket ]]; then echo "socket is available"; fi socket is available So the problem seems to be something else?!
