+That is a point I had never considered - used what sysinstall put into
+my fstab.
+
+Man fstab(5) says
+
+This field is used by the fsck(8) program to determine the order in
+which filesystem checks are done at reboot time. The root filesystem
+should be specified with a fs_passno of 1, and other filesystems should
+have a fs_passno of 2. Filesystems within a drive will be checked
+sequentially, but filesystems on different drives will be checked at the
+same time to utilize parallelism available in the hardware. If the sixth
+field is not present or zero, a value of zero is returned and fsck will
+assume that the filesystem does not need to be checked.
+
+May be read as a contradiction &quot;other filesystems should have a passno
+of 2&quot; and &quot;Filesystems within a drive will be checked sequentially&quot; -
+probably means that in this case the passno from fstab is ignored.
+
+The situation on the system I reported and generated by sysinstall
+corresponds precisely to what the man-page says: the root file system
+has a passno of 1, all other filesystem are configured to 2 - both the
+ext4 file systems that sit on the same drive as root (5 of them) and an
+ext4 filesystem that sits on an extra drive (used by backuppc).
+
+I now changed fstab to passno's
+ - root = 1
+ - the other ext4 systems which share the drive with root with
+increasing numbers: 2 and on
+ - the extra drive (backuppc) 1 - to be done in parallel to the root
+filesystem.
+
+Result: practically no change
