How do I prevent the mounts from failing and make the system continue on
with the boot process?

You could start by attaching your /etc/fstab and copy-pasting the output
of 'lsblk -f' with all partitions mounted.

It would also be useful to know what init system you are using
(ls -l /sbin/init) and if your mounts have any specials (LVM, encrypted,
NFS, RAID, etc.) basically anything besides plain extX filesystems
mounted from internal drives.

Kind regards,

No need for all that!

All my mounts are local PATA and SATA drives. The SATA drives are on an
adapter card. All the file systems are xfs, ext2, ext4 or swap and use
either /dir/dir, LABEL= or UUID=.
All very vanilla. No LVM, encrypted, NFS, RAID, etc. Doesn't make any
difference as *all* of the mounts are failing on the first pass!

I found a work around on a forum. Put "nofail" in the options field of
fstab. So now my entries contain "defaults,nofail" or "sw,pri=100,nofail" in
the options field.

Doesn't make any difference though. All the
    Dependency failed for ...
     Timeout waiting for ...
messages still occur, they just don't stop the boot process and the mounts
get done successfully later on.(??)

I can't tell what might have caused this as I don't re-boot after every
update, just when an update to the kernel occurs. I think it was about the
time that systemd was implemented as the boot screen looked different when
the mount failures started happening.

There are a lot of eyes on this list and someone might spot something
that you don't even think might have an impact.

But then it's your system, your rules ;)

Kind regards,

OK! Be my guest!!

One thing I have noticed is that it seems to do everything 2 or 3 times while it is booting, and it takes about 30 mins before my desktop (xfce) is up and functioning.
