Hi, initrd.gz is a badly compressed file... It tries to do the best and falls into old code part calling a pup_412.sfs as in the original 412.
Sorry can´t test pupngo yet!
Thanks for your efforts.

KJ: Again: thanks for test and report - sorry your save2cd wont work - its a nice feature to keep track of changes over time in the "save-file". Dillo font size can be adjusted by editing /usr/etc/dillorc: Add a line with "font_factor=1.2" after "fw_fontname=courier" and your fonts will get bigger. The shipped dillorc is a cut down of the original example file. Below the original.

escucha: Thanks for testing! initrd.gz is not gzipped (as the extension indicate) but lzma compressed. This should not prevent you from booting but it might be that the pup_412pupngo.sfs is not found on your hardware due to my move of all initrd kernel drivers into kernel.
I have no clue how to fix that other than go back to initrd with included kernel drivers needed at boot (which might be the best for pUPnGO 2012 dekstop usage...). The purpose of moving the drivers was to liberate the initrd from all the kernel-driver find and load stuff to ease port to other kernels - but I might have overlooked something (=failed).

PostPosted: Tue 19 Jun 2012, 18:03    Post subject: USB save  
goingnuts: Thanks for the ~/.dillo/dillorc code ... will update that when I get a working save file. I dug out a small (256MB) usb flashdrive. Used "install to USB" to install pUPnGo2012 from the CD ... installed fine from the .iso file on the HDD. Set up ethO and saved a bookmark then told it to poweroff and chose 'save to sdb1' but it still just shuts down without a save. This is the contents of the usb flashdrive now formatted to ext2. Boots and runs great just no save. Is save supposed to work when booting from usb?

Code:
# ls -la
total 34090
drwxr-xr-x  3 root root     1024 2012-06-19 11:36 .
drwxr-xr-x 13 root root      100 2012-06-19 16:47 ..
-rw-r--r--  1 root root       65 2012-06-19 11:36 extlinux.conf
-r--r--r--  1 root root    14336 2012-06-19 11:36 extlinux.sys
-rw-r--r--  1 root root   776017 2012-06-19 11:36 initrd.gz
drwx------  2 root root    12288 2012-06-19 11:36 lost+found
-rwx------  1 root root 16842752 2012-06-19 11:36 pup_412pupngo.sfs

-rwx------  1 root root 15413248 2012-06-19 11:36 zdrv_412.sfs

... am I missing something? Thanks KJ

I've been looking into compressed ext2 mounted with noatime and xip as a replacement for squashfs and unionfs and ext* and swapfs. So far it went well until I tried it on a slow usb flash drive over usb1. Other than that, speeds were typically faster on first run, slightly slower on reruns. The resave to cd would need modded too, but it cut the kernel size quite a bit and simplified boots, saves, installs, remasters etc...

KJ: You have same content on the usb as I get. I have same behavior when trying to save directly to usb - I never tested that - but will try to see if it can be made functional. Save to file works - so try that if you want.
technosaurus: Sounds interesting! Any details or scripts avaleble? Would that methode work with old kernels (2.0/2.2) as well?

I have only been testing using kernel command lines: root=/dev/sda1 rootfstype=ext2 and rootflags=noatime,xip,etc...
older kernels would have to be patched for the xip but would work without it (the initial patches are here:)
http://lwn.net/Articles/135442/

the compression patches are available back to 1.X
http://e2compr.sourceforge.net/

side note: while looking through the kernel code for the root*= parameters, I noticed /dev/ram0 is a special case that doesn't get switchrooted - thought of just using a squash on /usr and ext2 on root (I think this is similar to what DSL did with cramfs instead of squash, except that cramfs can be compressed and XIP, while squash is only compressed and is available in older kernels)

PostPosted: Wed 20 Jun 2012, 10:38    Post subject: USB flashdrive save  
goingnuts: Posting from pUPnGo2012 with a save file on a USB flashdrive. I should have tried the save to file option from the start. Save to file now works on both my regular USB formatted to ext2 and my partitioned USB drive (SD card in a USB convertor).

FYI freemem on the taskbar still reports system freemem not savefile freemem. Loaded ttuuxxxView which reports correctly

Thanks for all your help .... KJ

Tried to "peek" in your initrd.gz but non of the decompression apps appears capable to open the file so the usual
"{gunzip, bunzip2, bunzip, xz -d} -c initrd.gz | cpio -i" fails
Any suggestions?
Thx

technosaurus: Thanks - looks like it has some potential...
KJ: Nice! I will look at the code for the pmfree - thanks for notice!
mavrothal: Initrd.gz is a lzma archive:
Code:
#To unpack initrd.gz do:
lzma d initrd.gz initrd
cpio -idmv < initrd

"update": KJ: Cant reproduce the behavior of pmfree - here it shows free space in savefile only...

goingnuts: I'm having problems with the initrd.gz too.
When I run : # lzma d initrd.gz initrd

I get
Code:
lzma: d: No such file or directory
lzma: initrd: No such file or directory


The file is now renamed as initrd.gz.lzma
Running the next command (with the filename altered)
#cpio -idmv < initrd.gz.lzma
... throws up loads of lines of 'cpio: Malformed number ' followed by gibberish.

UPDATE: Solved it by renaming to initrd.lzma then running
Code:
xz --format=lzma --decompress initrd.lzma
then the cpio bit (#cpio -idmv < initrd) works ok.

Keef: Strange...the "lzma d initrd.gz initrd
cpio -idmv < initrd" works ok here...maybe version of lzma? I used lzma-458 to compress the initrd...

Again I am sorry to hear that but I have no clue. Are you booting from CD? Have you the possibility to try another computer?
