fsprobe
-------
- remove the lib/fsprobe.c wrapper for libblkid used in mount and fsck. Use
everywhere libblkid from util-linux only.
- update ./configure script
login-utils:
-----------
- use err() and warn() macros rather than fprintf(stderr, ...)
losetup
-------
- don't use ioclts if sysfs supports loop attributes (since 2.6.37,
block/loopN/loop/* files)
- don't open loopdev in looplist_next(), check if /sys/block/loopN/loop
exists and returns ll.name rather than file descriptor
- add sysfs based version of show_loop() and use it for non-root users
sysfs
-----
- add lib/sysfs.c with functions that read block device attributes from /sys.
For more details see devno.c from libblkid, lsblk.c and lomount.c.
lib/tt.c
--------
- allows to sort columns, for example sort lsblk(8) output by SIZE
libblkid
--------
- remove strerrr() from debug messages (use %m) to make BLKID_DEBUG= output
thread-safe
- add -<BE|LE> suffix to test images for native-endian filesystems (e.g. swap)
and add support for such functionality to tests/ts/blkid/low-probe
- add FSSIZE value -- filesystem size (klibc requirement)
- add support for dasd PT (used for example on s390)
blkid(8)
-------
- add something like "blkid --list-known" to list all supported filesystems/raids
- add a new option (-r) that allows to print removable block devices that
are missing in /proc/partitions, see blkid_probe_all_removable().
agetty:
------
- review code and make it more simple for normal console (see mingetty)
- merge functionality from unmaintained mingetty package to agetty
wipefs
------
- some filesystem (namely FAT) contains more magic strings, so if you erase
one magic string the FS is still detectable by libblkid. We have to inform
users that there is more valid magic string for the same FS.
fdisk(s)
--------
* sfdisk has to use rpmatch() for answers to y/n questions
(e.g. "Are you satisfied with this? [ynq]")
* sfdisk rounds to cylinders is -uM (megabyte units) is specified, this is
pretty stupid feature. It has to round to sectors if -uS or -uM is specified.
* Sun label support is completely useless for large disks, it uses number of
cylinders from on-disk-label where the geometry is stored by int16 values.
It seems better to completely ignore this stuff from the label and always
use geometry + BLKGETSIZE64 from kernel.
* use off_t instead "long long"
* catch SIGINT (Ctrl-C) and return to main menu.
From Red Hat bugzilla #545488:
While using fdisk normally, if you accidentally pressed the wrong button (to
start a sequence of questions for some operation, e.g. 'c' to create
partition). The tool tries too hard to keep asking you for valid input. You
can't provide a blank or invalid input to get it to break out of the current
dialog sequence and get back to the main menu.
* fdisk/* refactoring
* add GPT support (probably implement libfdisk)
misc
----
* switch_root:
- move all mountpoints to the newroot (there are hardcoded /proc /sys and /dev paths now)
- add --dont-move[=<list of dirs>] options
* use ngettext() for strings with plurals, for example
/* include/nls.h */
#define P_(id, id_plural, n) ngettext(id, id_plural, n)
printf(P_("%d used sector",
"%d used sectors", sectors),
sectors);
* use something better than gtk-doc (doxyden?)
* use TZ=UTC and LANG=en_US.UTF-8 for tests
* add NLS and err.h stuff to schedutils (chrt.c, taskset.c)
* add mllockall() and SCHED_FIFO to hwclock,
see http://lkml.org/lkml/2008/10/12/132
* use rpmatch() for all Y/N questions
* make chrt, taskset, ... threads aware. Currently these utils work with
group leader (master thread) and don't propagate requested changes to
the whole group of threads. It meas add a new option (e.g. -t):
chrt <prio> <pid> # master thread only
chrt -t <prio> <pid> # whole group of threads
Note that we need to scan /proc and call ched_set{scheduler,affinity}
syscalls for all individual threads.
* umount by label:
# mount LABEL=mylabel
# umount LABEL=mylabel
* mount -a -- reorder fstab entries by paths before mount (just idea only)
* mount -a (just idea only)

From: Szabolcs Szakacsits <szaka@sienet.hu>
In the past the right record order could be figured out easily by just
checking out fstab (if one knew what to look for) but considering the
fastly increasing number of user space file systems and their usage, with
their path, library, etc dependencies, it's getting trickier and is a black
magic for most users because they simply expect drives to be mounted
independently of their order in fstab.
One typical, wrongly edited fstab example is:
/dev/hda2 / ext3 defaults 1 1
/dev/hda1 /mnt/windows ntfs-3g defaults 0 0
/dev/hda3 /usr ext3 defaults 0 0
The events:
mount -> /sbin/mount.ntfs-3g ->
-> resolves to <path1>/ntfs-3g via a symlink ->
-> ntfs-3g requires at least <path2>/libfuse*
There are many potential solutions. For example installing everything on
the root file system which may be needed for successful mount. But this
is not always feasible or practical since we could end up putting almost
everything on the root file system in the end.
Another idea is an improved mount strategy:
do {
try to mount all unmounted entries
} while (not all mounted && at least one new was successfully mounted)
* rewrite ipcs to use /proc/sys/kernel rather than unreliable syscalls
(there are problems with 32bit userspace on 64bit kernel)
* minix v3
From: Matthias Koenig <mkoenig@suse.de>
Date: Tue, 25 Sep 2007 12:00:01 +0200
It seems that the kernel has support for minix fs v3
(though I have not tried it, just inspected some code when
trying to find a mkfs.minix issue).
It might be worth a thought implementing v3 support
(though I am not really sure how much people us minix fs ;-)
This might require some major code cleanup in mkfs.minix.
* add SELinux security contexts support to the 'ipcs' utility
http://bugzilla.redhat.com/show_bug.cgi?id=225342
Would be great to list the current system IPC Objects with their respective
security labels (where allowed) with something like 'ipcs -Z' - following the
way other tools reports those.
