v2.22 wish list

[Karel Zak]

This is my v2.22 wish list. The list contains large/invasive tasks only. 
Comments, volunteers, .... ? ;-)

 * release in May/Jun 2012

 * add PARTUUID= and PARTLABEL= support to mount/fsck by partition UUID/LABEL
   - add to libblkid blkid_evaluate_* API
   - support in libmount 
   - add regression tests

 * make uuidd (uuid daemon) compatible with systemd
   - add --no-fork
   - add --no-pid (pid file)
   - add systemd unit file
   - add #ifdef LIBUUID_EXEC_UUIDD to disable uuidd exec from library

 * fdisk
   - move mbr (dos) stuff to fdiskmbrlabel.c
   - add GPT support

 * clean up DBG() macro in libblkid
   - see libmount version

 * add dasd support to libblkid

 * non-recursive build-system (now many files from lib/ are compileted 
   more than once), see:
   http://thread.gmane.org/gmane.linux.utilities.util-linux-ng/3297

 * merge reject
   Michal L. is working on this task
   https://github.com/mluscon/util-linux/tree/eject

 * ???

You can maybe merge gptfdisk with fdisk

.

CC: mail list.

<sigh> why gmail does not alarm before sending, something like with
attachments, 'it seems you are replying only to person who send the
mail, did you mean replying to all?'

 In your implementation you're successfully resolved the problem with
 lib/*.c, but it's not non-recursive build.

 The non-recursive build means that there is only one Makefile.am, so
 make(1) is able to optimize compilation and SMP machines. See the old
 discussion with Flameeyel for more details.

 Your attempt could be a first step to make the build system more
 effective and maintainable. The second step (real non-recursive
 build) is more invasive.

 Notes:

  - we have SUID_{LDFLAGS,CFLAGS} so it would be better to have
    separate libcommon.la for suid utils

  - please define on $top_builddir based $($ul_libcommon_la) rather than use
    everywhere ../lib/libcommon.la

 I forgot one important item:

   * add device-mapper support to partx to make it compatible with
     kpartx (then we can remove kpartx from distros...)

Hi, JFYI (and to avoid duplicate work), I started on this:
