As a built-in. (Since I use CDRWs almost all the time while I work, I
reckoned it's easier and faster if Mr. Kernel is not looking for the
module[s] all the time, to load them. Which a bit puzzles me anyway:
If I have NO module used [nothing is compiled as a module with my
kernel] why the heck all the time at boot sequence I read about 10
seconds this "Calculating module dependencies"?)

Yep.

OK, I understand. Thanks.

Thanks for this notice, but...when it was not working, it was not
working with both variants, and when it works it works again with the
both variants. (-:
- From this you see that I still somehow managed to make it work, which
is very good thing, (: although I am not sure that I *understand* why
is working this way. Namely...

...your hint about pktsetup(8) moved me to put a glance at this man
page, and there I found this:
"
EXAMPLE
The following commands provide an example of using the packet device.
cdrwtool -d /dev/sr0 -q
pktsetup /dev/pktcdvd0 /dev/sr0
mount -t udf /dev/pktcdvd0 /mnt
...
umount /dev/pktcdvd0
pktsetup -d /dev/pktcdvd0
"
So...I saw that the (first) `pktsetup' command was *not* mentioned in
the HOWTO document on the wiki page, and I tried it, typing this way:
pktsetup /dev/pktcdvd0 /dev/cdroms/cdrom0
Then mounted a CD-RW of mine:
mount -t udf /dev/pktcdvd0 /mnt/cdrw
And, it simply worked! (-: The device for packet-writing (pktcdvd0)
was connected/linked to cdrom device (since there is no any *cdrw*
device), and they could work at the mount point /mnt/cdrw. That's how
I understand this. If I understand. Hence, the settings in
/etc/conf.d/cdrw which stated:
cdrw_list="/dev/pktcdvd0"
where wrong, and after I changed it in:
cdrw_list="/dev/cdroms/cdrom0"
the machine is pointed properly, going to cdroms, not to pktcdvd0,
which was the reason it's been spitting out the error message that
"pktcdvd0 is not a valid block device", earlier. (At least *I* think
it was the reason.)
After that it could [u]mount any CDRW simply by usual commands
(following fstab settings): "[u]mount /mnt/cdrw". There, it really
ended finely.
It *could not* read though any files on CDRWs formated in Windows (by
InCD), but they were mounted and open for writing anyway. (That's
strange but OK, I don't mind; those CDRWs are important to me only in
relation to Windows.) Then I formatted a new CDRW here in Linux, and
it works like baby/dove/charm/Tasmanian Devil. (: I have made my first
backup and the goal is fulfilled. "Mission accomplished".
I thank you, and all of you who participated in solving this `case',
very much for the help, hints and opinions, since I have done a pretty
important thing needed for my daily work, much faster than I would be
able to do if I would have to pick around myself alone, without
knowing more precisely *where* to pick.
Perhaps, the wiki page should include this "pktsetup" command too in
its HOWTO, since the lack of *it* actually was the reason I got this
previous error message. As I understand all this process.
Oh...I just feel fine now. <hg>
