Hi guys,

dogle I was thinking Ctrl+A inside the date file, then drag and drop to paste en-block to the new frugal partition.

norsiwel - thanks for joining the thread - I tried to do what dogle needs - I loaded a live DVD with saved date files then installed the pet in Utilities; but when I clicked to try to save to a "normal" save file I got the message:

Jasper, mtPaint has a Crop option in the Image drop-down menu that would be useful to you. Smile

Open a large image in mtPaint, left-click-and-drag to outline an area, then crop to remove everything outside the outlined area. Save and you're done.

Update:

Today Barry, in response to a blog comment, very kindly suggested editing the PUPSTATE file to offer PUPMODE=5 in order to bring up the 'save to file' option at shutdown. (Previously I had tried PUPMODE=12, thinking this to be appropriate to a frugal install, without success).

This works, and Puppy appears to prepare a pupsave file as requested.

Attempts to boot the new installation so far have failed. I have been hoping that this was just down to my customary SNAFU with GRUB configuration etc. but, rather worryingly, I am now unable to boot the box from a live CD without the good old 'Kernel panic - not syncin' message appearing, unless I invoke pfix=ram.

This suggest to me that the PUPMODE 5 method may be leading to some sort of deeper filesystem corruption, and so I have been attempting to replicate the problem on a different machine. Unfortunately, today I seem to be landed with a moribund optical drive, and therefore my efforts have so far produced only an exciting new range of cusswords.

If anyone else is up for for trying the PUPMODE=5 route, your feedback would be very welcome.

Hi dogle,

I did previously try using "5" and I also tried changing other lines in PUPSTATE as well, but without success.

However, Barry's comment seems to indicate that with a little more help you are likely to win.

My regards and good luck

Thanks Jasper, what happened in your case when you tried PUPMODE=5?

Hi dogle,

I tried "5" with so many combinations of other PUPSTATE line changes that I can't now remember any details, except that none of them worked.

Sometimes, trial and error works, but sometimes a deep knowledge is necessary and I was defeated.

My regards

I've had a little more success trying PUPMODE 5 on another box ... just a little.

Editing PUPMODE (only) to =5 enabled a pupsave file to be prepared on closing the multisession, as before. I was able to exorcise the GRUB demons, and get booted from the hard drive.

Most regular desktop and ROX icons were replaced by 'substitutes', i.e. lost.
Wallpaper selection had been preserved.
SM bookmarks had been preserved ... progress!

Running pfix=clean restored the icons. This process presumably reverses manual configuration edits e.g. to Abiword, which is a pain; unofficial PETs/printer drivers were gone.
CUPS configuration appeared to be retained, at least partly. Abiword custom templates were gone.

Once again, no cigar.

This evident filesystem corruption looks to me as if it may be a serious problem.

I've been doing this stuff with Puppy 431, frugal to clean (DBANned and freshly formatted) hard drives.

Are there any more PUPMODE 5 testers out there?

Hi dogle,

A thought for your consideration:

Suppose you were to make a frugal hdd installation and then delete its norrnal save file as part of the next step.

Then, with a current backup, run your DVD using puppy pfix=ram and then copy the PUPSTATE file (presumably from /etc/rc.d) to an external location and then exit without saving.

Then run your DVD in normal full mode and move its PUPSTATE file to another external location (so you can reinstate it later) and replace it by copying (or moving) the first PUPSTATE file.

Now, hopefully, on exit you can make a normal save file to your new frugal hdd location.

My regards

Another forum member used a similar method to save from a frugal installation to a multisession DVD - and reported that it worked. Anyway - good luck.

Many thanks, Jasper.

Sounds most ingenious ... but it's going to take a little while for me to get my head round it. :-)

Watch this space ....
