The symlinks are generated by asciidoctor and current dist_man_MANS
depends on order (nan page before man link). This solutions is useless
when execute "make -j". The real solution is to keep man pages in
separate variable and use only this variable evaluate what we need to
generate.

For example for hierarchy:
$ findmnt -oTARGET,ID,PARENT
TARGET ID PARENT
/mnt/A 802 62
└─/mnt/A/B 937 802
├─/mnt/A/B/C 964 937
│ └─/mnt/A/B/C 991 964
└─/mnt/A/B 1018 937
└─/mnt/A/B 1045 1018
we need umount in order (id): 1045, 1018, 991, 964, 937, 802. The current
code first tries 991 in 937 branch.

Besides some formatting tweaks, I've changed »lsblk(1)« into »lsblk(8)«
in the SEE ALSO section of mount.8.adoc. At least Archlinux and Debian
ship lsblk as a system administration command.
To build: meson build && ninja -C build
To run tests: ninja -C build check
To install for packaging: DESTDIR=/var/tmp/inst ninja -C build install
To install for realz: sudo ninja -C build install
v2:
- Optional items are now based on the 'feature' feature in meson.
Built libraries which are disabled turn into disabler() objects
and also poison any executables which link to them.
What is there:
- building of the binaries and libs and the python module
- installation of binaries, libs, python module, localization files,
man pages, pkgconfig files
- running of tests
- most options to configure build equivalently to the
./configure settings
Partially implemented:
- disabling of stuff when things missing. In the C code, the defines
are all used, so that should be fine. In the build system, some
files should be skipped, but that is probably not always done properly.
Getting this right might require some testing of various build option
combinations to get the details right.
Not implemented:
- static builds of fdisk and other binaries
- things marked with XXX or FIXME
- ???
Differences:
- .la files are not created. They are useless and everybody hates them.
- Requires.private in pkgconfig files are not present in the
autogenerated .pc file. Not sure if they should be there or not. If
necessary, they can be added by hand.
- man pages and systemd units are installed by the install target. Not
sure why 'make install' doesn't do that.
- the split between / and /usr is probably wrong. But it's all pointless
anyway, so maybe we could simplify things but not implementing it at
all under meson?
The function read_buffer() implements read and clear functionally, but
we do not differentiate between these actions in main() for error
messages, and one generic "dmesg: read kernel buffer failed" is used
in all cases. That's a bug.
This patch removes the "clear" action from read_buffer() and keeps it
for buffer reading only. The "clear" action is implemented in main()
by separate klogctl(SYSLOG_ACTION_CLEAR) for cases. It means also for
"dmesg --read-clear"; we do not use SYSLOG_ACTION_READ_CLEAR anymore.
Now "clear+read" is:
* syslog: SYSLOG_ACTION_READ_ALL + SYSLOG_ACTION_CLEAR
* kmsg: /dev/kmsg read() + SYSLOG_ACTION_CLEAR
In old versions "dmesg --syslog --read-clear" (syalog backed) was
implemented by logctl(SYSLOG_ACTION_READ_CLEAR) and it returns no
data for non-root users (due to EPERM), "dmesg --read-clear" (kmsg)
returns data and EPERM for the "clear" action.
Now the command "dmesg --syslog --read-clear" and "dmesg --read-clear"
behaves in the same way -- returns data and EPERM for the "clear"
action.
