   2  Note that items with (!) have high priority.
   3
   4 libblkid
   5 --------
   6   - (!) don't use fixed set of the static buffers for TAGs in blkid_probe,
   7     allocate all on the fly. It seems that for example btrfs is crazy enough
   8     to have LABELs longer than we have bufferes in libblkid
   9     https://bugzilla.redhat.com/show_bug.cgi?id=1164708
  10
  11 cfdisk
  12 ------
  13   - provide additional information about the current partitions (LABEL=, UUID=,
  14     filesystem type, size, usage, mountpoint, ...) just optionally add extra
  15     table between main menu and list of partitions.
  16
  17   - (!) add auto-sort support (sort partitions automatically) and
  18     --sort={auto,never,always} command line option. This feature should be
  19     enabled by default for logical partitions if we created all container (extended
  20     partition) in the current session.
  21
  22
  23 agetty
  24 -----
  25   - support default issue (/etc/issue) output for agetty to make it agetty
  26     usable on systems with empty /etc.
  27
  28     This change is little bit controversial, because now agetty prints nothing
  29     by default and it's probably used by admins to hide information about the
  30     system to unauthorized users. We already have --noissue to disable issue
  31     output. The question is if admins use this option, "rm /etc/issue" is
  32     probably easer than modify inittab (or systemd unit file).
  33
  34     Maybe we can implement it by --enable-agetty-default-issue compile option and
  35     move the decision to downstream maintainers ;-)
  36
  37 nsenter(1)
  38 ----------
  39  - read the default UID and GID from the target process.
  40    http://thread.gmane.org/gmane.linux.utilities.util-linux-ng/9553/focus=9585
  41
  42 hwlock
  43 ------
  44  - use /var/lib/hwclock/drift to store hw-clock drift numbers.
  45  - use /etc/adjtime as read-only for UTC/LOCAL information only
  46  - the /var/lib/hwclock/drift should be implemented backwardly compatible,
  47    it means use the file only if exists, otherwise follow /etc/adjtime
  48
  49 bash completion
  50 ---------------
  51 - Optional argument handling requires user to press backspace to get
  52   argument completion.
  53 - Comma separated value, e.g., --output 'value1,value2', are not
  54   completed for users.
  55
  56 libmount (mount/umount)
  57 -----------------------
  58
  59  - add options to control fstab/mtab mount options usage, something like:
  60
  61    --options-mode={ignore,append,prepend,replace}      MNT_OMODE_{IGNORE, ...}
  62    --options-source={fstab,mtab,disable}               MNT_OMODE_{FSTAB,MTAB,NOTAB}
  63    --options-source-force                              MNT_OMODE_FORCE
  64
  65    (all this already supported by libmount)
  66
  67 libsmartcols
  68 -----------
  69
  70  - (!) add SCOLS_FL_HIDDEN flag to make it possible to hide a column. Then we
  71    can use such column in lsblk(8) to only sort lines, but do not print the column.
  72
  73      lsblk -o NAME --sort SIZE
  74
  75 partx
  76 -----
  77
  78  - support mapping by device-mapper if argv[0] is "kpartx" or --dm option is used.
  79
  80
  81 docs
  82 ----
  83
  84  - (!) use something better than gtk-doc for libmount and libblkid (doxyden?)
  85
  86  - (!) add API documentation to libuuid
  87
  88
  89 login-utils:
  90 -----------
  91
  92   - consolidate newgrp(1)
  93     * we have "su --group/--supp-group" to switch between groups, newgrp(1) in
  94       util-linux and shadow-utils (and sg(1) alias in shadow-utils)
  95     * the unique functionality provided by newgpr(1) is support for group
  96       passwords [/etc/gshadow] -- do we really need this functionality?
  97     * maybe we can mark group-passwords as deprecated, and replace sg(1) and
  98       newgpr(1) with su(1) code. The another way is to ask fro group password in
  99       su --group too.
 100     * note that shadow-utils newgpr(1) provides support for syslog and audit log.
 101
 102 libblkid
 103 --------
 104
 105  - (!) don't use internally blkid_loff_t, rather use off_t, size_t, ssize_t,
 106        stdint.h types and so on...
 107
 108  - add FSSIZE value  -- filesystem size (klibc requirement)
 109
 110  - (!) add support for dasd PT (used for example on s390)
 111
 112 libfdisk
 113 --------
 114
 115    [always check libfdisk branch at github!]
 116
 117  - (!) add 'I'nfo fommand to print all details about specified partition
 118    (like offset, size, name, uuid, type, C/H/S, fstype)
 119
 120  - (!) add to "First sector" dialog a line with information about available
 121    gaps (free areas) to make it more user friendly if you want to skip
 122    any useless (small) areas between existing partitions.
 123    See https://bugzilla.redhat.com/show_bug.cgi?id=715114
 124
 125    (Note that libfdisk already supports freespace lists.)
 126
 127  - (!) add to fdisk "free space" command to print all available gaps
 128
 129  - add support for Apple Partition Map (see libblkid/src/partitions/mac.c)
 130    http://en.wikipedia.org/wiki/Apple_Partition_Map
 131
 132  - add "move end" command to move end of the last primary/extended partition.
 133    This feature seems very attractive to users who resizing their disks
 134    (for example in virtual machines).
 135
 136  - use off_t instead "long long"
 137
 138  - catch SIGINT (Ctrl-C) and return to main menu.
 139    From Red Hat bugzilla #545488:
 140
 141    While using fdisk normally, if you accidentally pressed the wrong button (to
 142    start a sequence of questions for some operation, e.g. 'c' to create
 143    partition).  The tool tries too hard to keep asking you for valid input.  You
 144    can't provide a blank or invalid input to get it to break out of the current
 145    dialog sequence and get back to the main menu.
 146
 147 misc
 148 ----
 149
 150  - add mllockall() and SCHED_FIFO to hwclock,
 151    see http://lkml.org/lkml/2008/10/12/132
 152
 153
 154 ---------------
 155 exotic requests
 156 ---------------
 157
 158  - add SELinux security contexts support to the 'ipcs' utility
 159    http://bugzilla.redhat.com/show_bug.cgi?id=225342
 160
 161    Would be great to list the current system IPC Objects with their respective
 162    security labels (where allowed) with something like 'ipcs -Z' - following the
 163    way other tools reports those.
