For unknown reason, I have not succeeded to set system level mount parameters using the '/etc/udisks2/mount_options.conf'. Should that work in MintPPC...? According to this article, at least the udisks2 version in MintPPC is new enough: ( http://storaged.org/doc/udisks2-api/latest/mount_options.html).

I have in my 'mount_options.conf' only these two lines active:

[defaults]
allow=exec,noexec,nodev,nosuid,noatime,nodiratime,ro,rw,sync,dirsync,noload

But if I mount some partition (which does _not_ have an entry in fstab), it still uses the default parameter from Kernel: 'relatime' instead of 'noatime, nodiratime', even if that line in my mount_options.conf does not allow 'relatime'.

Any idea what is wrong...?
