systemd mounts

Hi there,

A few weeks ago I came here with a problem that not all file systems being mounted at boot time (https://www.linuxquestions.org/quest...ot-4175677301/)

Turns out the probable cause, as suggested by @The Squash and @syg00 was the order the system mounts file systems and the fs that I wanted to mount depends on other fs to be mounted first (/home). This cause an erratic behavior. Sometimes it get mounted other times it don't, depending on which get mounted first.

So, to fix that I moved my mounts from /etc/fstab to a unit file to get mounted by systemd.

WantedBy=multi-user.targetThe problem is it works only 1 or 2 in 7 boots. Very annoying. When it don't work after the boot, "systemctl start home-miguel-Documents.mount" mounts the fs as expected, no warnings, no messages....

I have no indication of failure, other than that strange pattern Mounted/Umounting/mount: succeeded/Umount at end of status and, of course, reported by "journalctl -b -u home-miguel-Documents.mount"...

The current mount targets in my system (openSuSE tumbleweed) are:

LOAD = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB = The low-level unit activation state, values depend on unit type.

37 loaded units listed.
To show all installed unit files use 'systemctl list-unit-files'.What I am doing wrong ?
Why I can not get theses extra filesystems get mounted at boot time 100% of time ?

I appreciate any comments,

cheeers,
