Title: [SOLVED] Remastering question: how do I 'extract' (mount?) a .tcz?
Post by: PingPing on October 21, 2009, 04:54:12 PM

I want to remaster tcl 2.4.1 to include moc.tcz but I don't know whether I extract it with a special tool or mount it with a special tool ???

Mount it with the '-oloop' option.

Run Tiny Core 2.4.1, and have it mounted (If it is installed, delete its name from tcz2ram.lst and restart the computer).

You can then copy and paste it from /tmp/tcloop/ using Rox (you don't need to extract it or mount it).

If you use Rox, it will give you the option to merge with the other filesystem.

The following commands can be used as root:
mkdir /mnt/tmp
mount /path/to/extension.tcz /mnt/tmp -o loop
rsync -rlp /mnt/tmp /path/to/remaster/source

"rsync" will soon be gone from the base, so maybe "cp -a" might be better?

Since we are standardizing on squashfs, and therefore, it could be assumed that squashfs-tools-4.0.tcz is loaded, you can use unsquash.

unsquash --help

To view contents:
unsquashfs -ls moc.tcz
unsquashfs -lls moc.tcz

To extract into moc/ directory:
unsquash -info -d moc/ moc.tcz

Are there any speed advantages of using unsquash over rsync or cp for installing extensions to RAM?
If there is a speed advantage would the squashfs-tools be included in the base?

A special cp construct is being used in 2.5 with improved results and space savings too.
