Hmm...I just realized what the problem probably is. Try opening a shell using the following (incredibly long) command, then launch the chroot: opensh -c 'aegis-exec -c -a CAP::chown -a CAP::dac_override -a CAP::dac_read_search -a CAP::fowner -a CAP::fsetid -a CAP::kill -a CAP::setgid -a CAP::setuid -a CAP::setpcap -a CAP::linux_immutable -a CAP::net_bind_service -a CAP::net_broadcast -a CAP::net_admin -a CAP::net_raw -a CAP::ipc_lock -a CAP::ipc_owner -a CAP::sys_module -a CAP::sys_rawio -a CAP::sys_chroot -a CAP::sys_ptrace -a CAP::sys_pacct -a CAP::sys_admin -a CAP::sys_boot -a CAP::sys_nice -a CAP::sys_resource -a CAP::sys_time -a CAP::sys_tty_config -a CAP::mknod -a CAP::lease -a CAP::audit_write -a CAP::audit_control -a CAP::setfcap -a CAP::mac_override -a CAP::mac_admin sh'
