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.
|
|
|
|
|
|
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 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)

|
|
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

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.
