I made this utility awhile back & forum post interest has prompted me to post it.
I've reworked it a number of times & I think it's getting pretty close to done.

Merges multi. sources into a new SFS file, this reduces the number of unions.
Sources it will use: "dirs.", ".2fs", ".3fs", "NO extention ext2", & ".sfs".

Extract the file & move the dir. "/mksfs" to "/root/my-applications/mksfs".

This app. is in TESTING, use at your own risk!

Tried out the mksfs app today. My test was to combine 5 sfs files. Here's what I found:

Limit of 4 sfs files, not enough loop devices for any more. I had two sfs files loaded at the time, devx, and my own "mega sfs" file (KDE, openoffice, web, pgs) Could this be noted somewhere in the utility?

At this point I dropped out 1 sfs leaving 4 to run the test.

The end product contained all the data from the original files, but each sfs was in a directory, "-mnt-home-KDE....", "-mnt-home-openoffice....", etc. instead of combined in usr, etc, root, opt, etc.

Lastly, the 4 loop devices that were used, were not umounted when finished.

Overall, it looks like it will be a good utility since more and more sfs files are being created. I made my "mega file" from the command line, but this could be alot easier.

Hi JB4x4; Thanks for the feed-back, I rely on users alot to insure my crud works.

Loop devices:
Puppy has only 8 loop devices, I've read that the kernel must be compiled to use
more, or a kernel arg. is needed, or line must be added to /etc/modules.conf (I think).
I see no reason why the kernel wouldn't use more of them, but...
I've used code to make more loop devices for Puppy-1 which only had 5 of them.
They don't take up any space, it'd be real nice if Barry would include
more, say at least 12 or better yet 16 of them & enable them of course.

Currently the only way to have more source files is to reboot with only the
main SFS & Save files (rename any others), this'll allow for 6 source files.

I don't know what the deal with the SFS file having everything in sub dirs.
No one else reported this problem yet, I'll wait & see if it's a flaw...
The mksquashfs command is the same one Barry uses to remaster Puppy.

Changes:
I fixed the missing trailing "/" for paths that're typed in.
It should unmount the source files now.
I also changed the way it makes the mount point dirs. for file mounting.

I posted the new version above... ALOT of MAJOR CHANGES.

This looks interesting. I shall have a good look at it in the next few days.
