It works now!
It seems that blog shows an old style syntax. Found others, though,
like the following:
http://www.viraj.org/b2evolution/blogs/index.php/2007/05/03/ubuntu_server_and_unionfs
but for nowadays Gentoo systems (at least) the correct syntax is like
the following (which works for me):
/dev/sda3 /.var.rw <http://var.rw> ext4
noatime,defaults 0 2
union /var unionfs
default_permissions,allow_other,use_ino,nonempty,suid,cow,dirs=/.var.rw
<http://var.rw>=rw:/.var.ro <http://var.ro>=ro 0 0
tmpfs /.etc.rw <http://etc.rw> tmpfs
defaults,mode=755 0 0
union /etc unionfs
default_permissions,allow_other,use_ino,nonempty,suid,cow,dirs=/.etc.rw
<http://etc.rw>=rw:/.etc.ro <http://etc.ro>=ro 0 0
Directories /.var.ro <http://var.ro> and /.etc.ro <http://etc.ro>
are already present on the root file system.
It seems that this was the problem from the beginning, not been able to
correctly mount those partitions at the proper and usual time.
This brings up a related issue, I filed a bug about [1].
Documenting how to use UUIDs in the installation handbook. I kept the
bug generic, but I had Arm architectures in mine all along. With the
porting of Grub2 to Arm (Linaro) is seems that soon there will be a
myriad of file systems to run on the newer Arm systems [2] [3]. I
struggle on how to write up the bug, so feel encourage to think about
ways to simply or unify the installation handbooks, related to grub2,
supporting a variety of new file systems, particularly related to arm.
The existing arm handbook [4] is woefully out of date. Granted, the
gentoo-embedded handbook [5] is great, it does not address gentoo-distro
installation on the newer arm (64 bit)chips, akin to the x86 offerings.
So folks are resorting to all sorts of extraneous documentation [6]
Filing bugs (new or edit mine) to make the docs better, enhances
Gentoo's appeal, imho.
