Squashfs how to?

[noob001]

I was wondering what I need to edit to replace cloop with squashfs? I've built a kernel with squashfs support but what next?

Firmsy told here in another tread that he's going to do a howto of replacing cloop to squashfs. Just wait until he has time to do that :)


But something to ponder. If you want to use squashfs to make bigger KNOPPIX image than 2 gig, I have news for you. Believe it or not but cloop device don't have that 2 gig limit if you change some things in minirt.gz's linuxrc file.

If you change test -f to test -r in linuxrc, that's it! At this time I have 2066 MB /cdrom/KNOPPIX/KNOPPIX image and it boots fine. Hope that someone could tell me, why is this. But anyhow, it works!

Wow. Can you explain that in a little more detail?

I'm still working on a 3.7 remaster Do you think it will still work? I found several instances of test -f. Mostly related to scsi. Or is it time to start over on the remaster with a new version of KNOPPIX.

Why not? Knoppix 3.7 didn't use unionfs by default. With Debian it is not so important what version you have if you do apt-get dist-upgrade. My version has been Debian unstable and only minor troubles has been along the way. Changing from my X.org 6.9 to X.org 7.0 was solved by Kanotix's scripts - thanks to Kano for his excellent work.

But if you are not in a hurry, wait until Knoppix 5.0.1 is released and use it as a base in your remasterings. It makes your life little easier ;) In there is also that 'test 'r' used instead of 'test -f'.

I noticed that 2 gig limit can be exceeded in my own remastering because my KNOPPIX image was little over 2048 MB and I forget to check that - and couldn't boot with my old minirt.gz using my old linuxrc. It didn't boot because 2 gig limit was exceeded. But I had also some testing minirt.gz files - one was using linuxrc from Knoppix 5.0 and it booted! Then I compared those two linuxrc files with 3diff3 and noticed that difference in using test program. Changing -f to -r solved my 2 gig limit problem! Now my KNOPPIX image is about 2.2 gig and I can install new programs without thinking that 2 gig limit!

Here's an example using 'test 'r':


if test -r /cdrom/$KNOPPIX_DIR/$KNOPPIX_NAME; then
echo -n "${CRE} ${GREEN}Accessing KNOPPIX ${MEDIUM} at ${MAGENTA}$i${GREEN}...${NORMAL}"
FOUND_KNOPPIX="$i"
