   6   - use unsigned sizes for columns and lines
   7   - check for limits to avoid segfaults
   8   - make it more robust

  11 cal
  12 ---
  13    - add option to print calendar in vertical way
  14      https://github.com/karelzak/util-linux/issues/604
  15    - support another --reforms, see for example freebsd version
  16      https://github.com/freebsd/freebsd/blob/master/usr.bin/ncal/ncal.c#L72

  18 lscpu
  19 -----
  20   - read cpuid and uname information from file if --sysroot is specified, then
  21     we can prepare regression tests completely independent on hw and architecture.
  22
  23 lsblk
  24 -----
  25   - currently it does not show mountpoint for all devices in btrfs RAID. It's because
  26     /proc/#/mountinfo contains reference to the one device only. Maybe we can add some
  27     btrfs specific code to provide a better output for FS based stacks. Not sure.

  30 nsenter(1)
  31 ----------
  32  - read the default UID and GID from the target process.
  33    http://thread.gmane.org/gmane.linux.utilities.util-linux-ng/9553/focus=9585
  34
  35 hwclock
  36 ------
  37  - use /var/lib/hwclock/drift to store hw-clock drift numbers.
  38  - use /etc/adjtime as read-only for UTC/LOCAL information only
  39  - the /var/lib/hwclock/drift should be implemented backwardly compatible,
  40    it means use the file only if exists, otherwise follow /etc/adjtime
  41
  42 bash completion
  43 ---------------
  44 - Optional argument handling requires user to press backspace to get
  45   argument completion.
  46 - Comma separated value, e.g., --output 'value1,value2', are not
  47   completed for users.
  48
  49 libmount (mount/umount)
  50 -----------------------
  51
  52  - add --onlyonce to force mount(8) to check if mountpoint is already used. Now
  53    "already mounted" detection is used for --all only. The problem is if you
  54    call "mount <mountpoint>" more than once for in fstab defined tmpfs (or network
  55    filesystem etc.). In this case kernel does not return EBUSY, but a new instance
  56    of the FS is created. https://github.com/karelzak/util-linux/issues/448
  57    (... just idea, maybe wrong idea)
  58
  59  - support CAP_SYS_ADMIN; for mount(2) syscall the CAP_SYS_ADMIN is good
  60    enough. Unfortunately, mount(8) does more things like check for filesystem
  61    type (but it's usually done by udev, so root perms are unnecessary), create
  62    loop devices, write to /run/mount/utab or /etc/mtab, etc.
  63
  64    It would be nice to improve libmount to check for CAP_SYS_ADMIN if suid not
  65    set and allow to use it for simple tasks where no another operation is
  66    necessary.
  67
  68 partx
  69 -----
  70
  71  - support mapping by device-mapper if argv[0] is "kpartx" or --dm option is used.
  72
  73
  74 getopt
  75 ------
  76   It would be great if getopt could optionally ignore unknown options.
  77   Currently, it outputs -- for every option it doesn't recognize but leaving the
  78   option as it is could beneficial wrapper scripts which could then pass the
  79   options they don't recognize as they are to the command they are wrapping.

  81
  82 docs
  83 ----
  84
  85  - (!) use something better than gtk-doc for libmount and libblkid (doxyden?)
  86
  87  - (!) add API documentation to libuuid
  88
  89
  90 login-utils:
  91 -----------
  92
  93   - consolidate newgrp(1)
  94     * we have "su --group/--supp-group" to switch between groups, newgrp(1) in
  95       util-linux and shadow-utils (and sg(1) alias in shadow-utils)
  96     * the unique functionality provided by newgpr(1) is support for group
  97       passwords [/etc/gshadow] -- do we really need this functionality?
  98     * maybe we can mark group-passwords as deprecated, and replace sg(1) and
  99       newgpr(1) with su(1) code. The another way is to ask for group password in
 100       su --group too.
 101     * note that shadow-utils newgpr(1) provides support for syslog and audit log.
 102
 103
 104 libblkid
 105 --------
 106
 107  - (!) add support for BitLocker Drive Encryption
 108    https://github.com/karelzak/util-linux/issues/617
 109    https://github.com/libyal/libbde/blob/master/documentation/BitLocker%20Drive%20Encryption%20(BDE)%20format.asciidoc
 110
 111  - (!) add support for dasd PT (used for example on s390)
 112
 113 libfdisk
 114 --------
 115
 116  - add support for Apple Partition Map (see libblkid/src/partitions/mac.c)
 117    http://en.wikipedia.org/wiki/Apple_Partition_Map
 118
 119  - add support for nested PT (e.g. hybrid MBR) to scripts
 120    * add "nested-label:" block to sfdisk --dump
 121    * add "nested-partitiontable" to sfdisk --JSON
 122    * support nested labels parsing from dump
 123    see https://github.com/karelzak/util-linux/issues/850
 124
 125 sfdisk
 126 ------
 127
 128  - don't backup PT in interactive mode before write to the devices is requested,
 129    see https://github.com/karelzak/util-linux/issues/852
 130
 131 misc
 132 ----
 133
 134  - add mllockall() and SCHED_FIFO to hwclock,
 135    see http://lkml.org/lkml/2008/10/12/132
 136
 137
 138 ---------------
 139 exotic requests
 140 ---------------
 141
 142  - add SELinux security contexts support to the 'ipcs' utility
 143    http://bugzilla.redhat.com/show_bug.cgi?id=225342
 144
 145    Would be great to list the current system IPC Objects with their respective
 146    security labels (where allowed) with something like 'ipcs -Z' - following the
 147    way other tools reports those.
