When attempting to access manpages an unexpected behavior can be observed on
leap 42.2.

man systemd.mount brings "Kein Handbucheintrag f�r systemd.mount vorhanden"
man 5 systemd.mount brings the expected, the manpage for systemd.mount. The
file exists and can be found in the apropriate location
/usr/share/man/man5/systemd.mount.5.gz. The permissions are as expected.

I cannot observe this on leap 42.1. The file

/etc/manpath.conf 

do not differ between leap-42.1 and leap-42.2, this cannot be the reason.
Moreover, MANPATH shows identical results on both systems.

Downgrading man from the version on leap-42.2 to the version on leap-42.1 does
not help.

The strange thing: some manpages may be accessed sometimes, for example man
auto.master may work, sometimes even systemd.mount is functional, but in the
very moment I start a new xterm and say man systemd.mount or man auto.master it
doesn't work any more. 

man 5 systemd.mount works always as readily mentioned, however, this implies
you know the section where the corresponding manpage can be found - this should
not be required.

Thank you for looking into this,
