   4 script (lib/pty-session.c)
   5 --------------------------
   6   - (!) add #ifdefs and optional code for non-signalfd() systems

  10 ----
  11   - use terminal hyperlinks (for example for --help)
  12     try on terminal: printf 'For more details see \e]8;;man:fdisk(8)\e\\fdisk(8)\e]8;;\e\\.\n'

  15 rev
  16 ---
  17   - support huge input lines (for example read input by small fixed buffer
  18     rather than try allocate all buffer for a whole line)
  19     see: https://github.com/karelzak/util-linux/issues/972
  20
  21 col
  22 ---
  23   - use unsigned sizes for columns and lines
  24   - check for limits to avoid segfaults
  25   - make it more robust
  26   https://github.com/karelzak/util-linux/issues/749
  27
  28 cal
  29 ---
  30    - support another --reforms, see for example freebsd version
  31      https://github.com/freebsd/freebsd/blob/master/usr.bin/ncal/ncal.c#L72
  32
  33 lscpu
  34 -----
  35   - read cpuid and uname information from file if --sysroot is specified, then
  36     we can prepare regression tests completely independent on hw and architecture.
  37
  38 lsblk
  39 -----
  40   - currently it does not show mountpoint for all devices in btrfs RAID. It's because
  41     /proc/#/mountinfo contains reference to the one device only. Maybe we can add some
  42     btrfs specific code to provide a better output for FS based stacks. Not sure.

  45 nsenter(1)
  46 ----------
  47  - read the default UID and GID from the target process.
  48    http://thread.gmane.org/gmane.linux.utilities.util-linux-ng/9553/focus=9585
  49
  50 hwclock
  51 ------
  52  - use /var/lib/hwclock/drift to store hw-clock drift numbers.
  53  - use /etc/adjtime as read-only for UTC/LOCAL information only
  54  - the /var/lib/hwclock/drift should be implemented backwardly compatible,
  55    it means use the file only if exists, otherwise follow /etc/adjtime
  56
  57 bash completion
  58 ---------------
  59 - Optional argument handling requires user to press backspace to get
  60   argument completion.
  61 - Comma separated value, e.g., --output 'value1,value2', are not
  62   completed for users.
  63
  64 libmount (mount/umount)
  65 -----------------------
  66
  67  - mnt_context_get_excode() does not return error messages from /sbin/[u]mount.<type>
  68    external helpers. It is disadvantages in same cases (non-terminal progarms).
  69    The solution is to use pipe(), keep output from helper in memory and return it later
  70    by mnt_context_get_excode() (or mnt_context_get_helper_output(), etc.). This feature
  71    should be optional and disabled by default.
  72    see: https://github.com/karelzak/util-linux/issues/1208
  73
  74  - add --onlyonce to force mount(8) to check if mountpoint is already used. Now
  75    "already mounted" detection is used for --all only. The problem is if you
  76    call "mount <mountpoint>" more than once for in fstab defined tmpfs (or network
  77    filesystem etc.). In this case kernel does not return EBUSY, but a new instance
  78    of the FS is created. https://github.com/karelzak/util-linux/issues/448
  79    (... just idea, maybe wrong idea)
  80
  81 partx
  82 -----
  83
  84  - support mapping by device-mapper if argv[0] is "kpartx" or --dm option is used.
  85
  86
  87 getopt
  88 ------
  89   It would be great if getopt could optionally ignore unknown options.
  90   Currently, it outputs -- for every option it doesn't recognize but leaving the
  91   option as it is could beneficial wrapper scripts which could then pass the
  92   options they don't recognize as they are to the command they are wrapping.

  95 docs
  96 ----
  97
  98  - (!) use something better than gtk-doc for libmount and libblkid (doxyden?)
  99
 100  - (!) add API documentation to libuuid
 101
 102  - (!) rewrite man pages to AsciiDoc and generate final man pages by Asciidoctor & Docbook
 103
 104 login-utils:
 105 -----------
 106
 107   - consolidate newgrp(1)
 108     * we have "su --group/--supp-group" to switch between groups, newgrp(1) in
 109       util-linux and shadow-utils (and sg(1) alias in shadow-utils)
 110     * the unique functionality provided by newgpr(1) is support for group
 111       passwords [/etc/gshadow] -- do we really need this functionality?
 112     * maybe we can mark group-passwords as deprecated, and replace sg(1) and
 113       newgpr(1) with su(1) code. The another way is to ask for group password in
 114       su --group too.
 115     * note that shadow-utils newgpr(1) provides support for syslog and audit log.
 116
 117
 118 libblkid
 119 --------
 120
 121  - extend ZFS proper to scan for more uberblocks if BLKID_SUBLKS_MAGIC flag is set.
 122    This solution will make wipefs(8) more usable as ZFS is extremely variable with
 123    additional root blocks locations. See  https://github.com/karelzak/util-linux/issues/1228
 124
 125  - (!) add support for BitLocker Drive Encryption
 126    https://github.com/karelzak/util-linux/issues/617
 127    https://github.com/libyal/libbde/blob/master/documentation/BitLocker%20Drive%20Encryption%20(BDE)%20format.asciidoc
 128
 129  - (!) add support for dasd PT (used for example on s390)
 130
 131 libfdisk
 132 --------
 133
 134  - add support for Apple Partition Map (see libblkid/src/partitions/mac.c)
 135    http://en.wikipedia.org/wiki/Apple_Partition_Map
 136
 137  - add support for nested PT (e.g. hybrid MBR) to scripts
 138    * add "nested-label:" block to sfdisk --dump
 139    * add "nested-partitiontable" to sfdisk --JSON
 140    * support nested labels parsing from dump
 141    see https://github.com/karelzak/util-linux/issues/850
 142
 143 sfdisk
 144 ------
 145
 146  - don't backup PT in interactive mode before write to the devices is requested,
 147    see https://github.com/karelzak/util-linux/issues/852
 148
 149 misc
 150 ----
 151
 152  - add mllockall() and SCHED_FIFO to hwclock,
 153    see http://lkml.org/lkml/2008/10/12/132
 154
 155
 156 ---------------
 157 exotic requests
 158 ---------------
 159
 160  - add SELinux security contexts support to the 'ipcs' utility
 161    http://bugzilla.redhat.com/show_bug.cgi?id=225342
 162
 163    Would be great to list the current system IPC Objects with their respective
 164    security labels (where allowed) with something like 'ipcs -Z' - following the
 165    way other tools reports those.
