I have discovered something that I should have noticed a long time ago,
that is, that the entire drive is owned by root. That would explain the
fact that   the -o --owner and -g --group options are not working in
rsync, leaving the owner of the files the mysterious user 1026.
(I'm betting user 1026 is root on my Xubuntu.) "And why is the drive
owned by root?" you ask. That is because the only way I could mount it
was with sudo.

Fast forward to after several hours of googling and it appears that I
can mount it as jjj only if it is in fstab with 'user' as one of the
options. "No problem," I thought, "I'll just edit up my fstab file."
Here is the line I cooked up:

//synology.local/synology/ /media/jjj/Synology auto auto,user,rw 0 0

My mount command (sans sudo) is:

mount.cifs //synology.local/synology/ /media/jjj/Synology/
	--verbose -o user=jjj

Unfortunately, something is wrong:

mount.cifs //synology.local/synology/ /media/jjj/Synology/ --verbose -o
	user=jjj 
Password for jjj@//synology.local/synology/: 
mount.cifs kernel mount options:
ip=192.168.0.101,unc=\\synology.local\synology,auto,uid=1000,gid=1000,user=jjj,pass=********
mount error(22): Invalid argument 
Refer to the mount.cifs(8) manual	page (e.g. man mount.cifs)

It would have been really helpful if the error message gave me some
clue as to which argument is not valid. I don't even know if it's an
argument in the command or in the fstab line.

So far I have about a dozen hours invested in trying to get this thing
working and I'm close to giving up. Perhaps in the morning my attitude
will be refreshed. In the meantime, if anyone sees anything in the
mount command or the fstab line, please let me know. Any suggestions
are better than what I have now.

I opened the mount.cifs man page and read everything I could
understand.
