Ok, let's take on your questions one at a time...
inoxidabile wrote:- Starting from CD, the first row at bottom of screen isn't visible (I remembered that F3 shows a normal text white on black and then I did in this way).
Can't speak to this since I've never experienced it on my setup.
inoxidabile wrote:- A couple of messages during boot (on a frugal install type) say "filesystem=ext2fs partition type 083"... it seems strange, because all the drive has been formatted as ext3 and also the save file has been choosed on ext3.
Carolina has been developed on ext4. I don't know if using it will fix the issue, but it's worth a try.
inoxidabile wrote:- Certain apps takes about five seconds to start (e.g. Firefox) but there isn't any signal indicating that it's loading.
The same happens at shutdown, it takes some time, while nothing happens and then there is the temptation to think "what's happening wrong?"
I'll keep this in mind moving forward. Carolina is a bit of a pig; because of it's size, it's a bit sluggish by Puppy standards. Perhaps in future versions, I'll add notifications for longer-starting apps.
inoxidabile wrote:- In the update of repos there is also puppy4 but it isn't present in the pet list in PPM. Moreover, if the Saluki (and maybe other...) package are compatible, why they aren't available in PPM?
The Saluki packages are included in the Carolina repo, along with many other pet additions not available in the Saluki repo. The reason that the Saluki repo isn't offered is because of this, and due to the fact that some of the pets offered in the Saluki repo have been modified to work with Carolina. In short, the Carolina repo includes all of Saluki's, and then some, modified to work with Carolina. As far as Puppy4 packages are concerned, at one time a user could enter the PPM configuration and choose which repo's they'd like displayed (5 repos max). Somehow, that got lost in the transition. I'll have to look into that; the ability to choose the Puppy4 repose should be available, but obviously at present it is not.

) it could be wise to suggest to not use the root-home because, if the size of personal file is small the system could have problems.
If you're refering to the 'custom-builder' tool, yes, it's the bomb. It's very flexible, and even allows for swapping out the kernel. Again, in future releases, I'll keep in mind your advice.
inoxidabile wrote:- The acpitool remains in powersave even if not needed, could it be corrected or the only way is as suggested in a post by rg66 ? (that's equal to not have it).
The Carolina acpitool is currently configured to default to powersave on laptops with no ac-power, and turbo otherwise; however, it should be configurable if using ac-power. Perhaps you need to enable the correct driver using the Control Panel-->Hardware-->CPU Frequency Scaling Tool. You may have to do a Google search to find the correct driver to use for your setup, but it should be adjustable.
inoxidabile wrote:-A question: how can I have a screensaver (just to avoid the blank screen after some time of inactivity) but without setup password?
Lastly, there is the topic I've seen about Firefox, a corruption or a variation could require a fresh install, maybe it could be able to happen to other programs.
Honestly, I cannot answer this question due to the fact that I don't use a screensaver. The underlying workings are the same as they would be with Saluki - in otherwords, concerning a screensaver, nothing should've changed from Saluki to Carolina. Hopefully someone more clued-up on this subject can contribute to this thread concerning this matter. As far as other applications trying to update, as far as we know, Firefox is the only one that does so.
