NEUTRALITY:

      The stuff in util-linux should be rather distribution-neutral.
      No RPMs/DEBs/... are provided - get yours from your distributor.


VERSION SCHEMA:

      Standard releases:

          <major>.<minor>[.<maint>[.<bugfix>]]

             major = fatal and deep changes
             minor = typical release with new features
             maint = maintenance releases; bug fixes only
             bugfix = unplanned releases for critical/security bugs

      Development releases:

         <major>.<minor>-rc<N>


COMPILATION:

      See the INSTALL file for more details.

      Notes:
            * use SUID_CFLAGS and SUID_LDFLAGS when you want to define special
              compiler options for typical suid programs, for example:

                  ./configure SUID_CFLAGS="-fpie" SUID_LDFLAGS="-pie"

              This feature is currently supported for chfn, chsh, newgrp,
              write, mount, and umount.


STATIC LINKING:

      Use --enable-static-programs[=LIST] configure option when you want to use
      statically linked programs.

      Note, mount(8) uses get{pw,gr}nam() and getpwuid() functions for
      translation from username and groupname to UID and GID. These functions
      could be implemented by dynamically loaded independent modules (NSS) in
      your libc (e.g. glibc). These modules are not statically linked to
      mount(8) and mount.static is still using dlopen() like dynamically
      linked version.

      The translation won't work in environment where NSS modules are
      not installed.

      For example normal system (NSS modules are available):

              # ./mount.static -v -f -n -ouid=kzak /mnt/foo
              LABEL=/mnt/foo on /mnt/foo type vfat (rw,uid=500)
                                                       ^^^^^^^
      and without NSS modules:

              # chroot . ./mount.static -v -f -n -ouid=kzak /mnt/win
              LABEL=/mnt/win on /mnt/win type vfat (rw,uid=kzak)
                                                       ^^^^^^^^
