Now we + compose only output (by libsmartcols). It would be better to have in memory + complete tree of the devices and generate the output from this tree. It will + make code more readable and allow to generate output in more ways -- for + example for RAIDs (https://github.com/karelzak/util-linux/issues/616) + + - currently it does not show mountpoint for all devices in btrfs RAID. It's because + /proc/#/mountinfo contains reference to the one device only. Maybe we can add some + btrfs specific code to provide a better output for FS based stacks.

Now + "already mounted" detection is used for --all only. The problem is if you + call "mount <mountpoint>" more than once for in fstab defined tmpfs (or network + filesystem etc.). In this case kernel does not return EBUSY, but a new instance + of the FS is created. https://github.com/karelzak/util-linux/issues/448 + (... just idea, maybe wrong idea) + + - support CAP_SYS_ADMIN; for mount(2) syscall the CAP_SYS_ADMIN is good + enough. Unfortunately, mount(8) does more things like check for filesystem + type (but it's usually done by udev, so root perms are unnecessary), create + loop devices, write to /run/mount/utab or /etc/mtab, etc. + + It would be nice to improve libmount to check for CAP_SYS_ADMIN if suid not + set and allow to use it for simple tasks where no another operation is + necessary. + +partx +----- + + - support mapping by device-mapper if argv[0] is "kpartx" or --dm option is used. + + +getopt +------ + It would be great if getopt could optionally ignore unknown options. + Currently, it outputs -- for every option it doesn't recognize but leaving the + option as it is could beneficial wrapper scripts which could then pass the + options they don't recognize as they are to the command they are wrapping. + https://github.com/karelzak/util-linux/issues/701 + +docs +---- + + - (!) use something better than gtk-doc for libmount and libblkid (doxyden?) + + - (!) add API documentation to libuuid + + +login-utils: +----------- + + - consolidate newgrp(1) + * we have "su --group/--supp-group" to switch between groups, newgrp(1) in + util-linux and shadow-utils (and sg(1) alias in shadow-utils) + * the unique functionality provided by newgpr(1) is support for group + passwords [/etc/gshadow] -- do we really need this functionality? + * maybe we can mark group-passwords as deprecated, and replace sg(1) and + newgpr(1) with su(1) code.
