No, I don't think so. /sbin/runit-init behave differently in case it
executed as process N1 (do process N1 work) and in other cases (execute
reboot or halt procedure).

To make sure: I've just did paxctl -m /sbin/runit-init, boot kernel
compiled on this server (which boot ONLY with paxctl -m), then run:

    # paxctl -zxe /sbin/runit-init
    # /sbin/runit-init 
    usage: /sbin/runit-init 0|6

No segfault here, and strace won't help.


Here is extract from that's kernel .config:

    # gzip -dc /proc/config.gz | egrep -i 'pax|pae'
    CONFIG_X86_PAE=y
    # PaX
    CONFIG_PAX_ENABLE_PAE=y
    CONFIG_PAX=y
    # PaX Control
    # CONFIG_PAX_SOFTMODE is not set
    CONFIG_PAX_EI_PAX=y
    CONFIG_PAX_PT_PAX_FLAGS=y
    CONFIG_PAX_NO_ACL_FLAGS=y
    # CONFIG_PAX_HAVE_ACL_FLAGS is not set
    # CONFIG_PAX_HOOK_ACL_FLAGS is not set
    CONFIG_PAX_NOEXEC=y
    # CONFIG_PAX_PAGEEXEC is not set
    CONFIG_PAX_SEGMEXEC=y
    # CONFIG_PAX_EMUTRAMP is not set
    CONFIG_PAX_MPROTECT=y
    CONFIG_PAX_ELFRELOCS=y
    # CONFIG_PAX_KERNEXEC is not set
    CONFIG_PAX_ASLR=y
    CONFIG_PAX_RANDKSTACK=y
    CONFIG_PAX_RANDUSTACK=y
    CONFIG_PAX_RANDMMAP=y
    # CONFIG_PAX_MEMORY_SANITIZE is not set
    CONFIG_PAX_MEMORY_UDEREF=y
    CONFIG_PAX_REFCOUNT=y
    CONFIG_PAX_USERCOPY=y

Full .config in attach.
