Are 'user_more.sfs', 'user_devx.sfs' related to unionfs?

#1 Post by willhunt »

just a few questions as I am new to linux the two files
user_more.sfs and user_devx.sfs are union filesystem files correct?
this article
sez that unionfs mounts can be controlled by a file in the root directory
/.unionfs is this correct?

can this file be used to stop conflicts in the filesystem
such as are occuring with devx and the kde usr_more file
if someone could point to a site that would offer me a more complete
understanding of unionfs

Willhunt,

usr_more.sfs and usr_devx.sfs are squashfs file (sfs). It provides high compression ratio. It would astonish you that uncompressed usr_more.sfs contains 125 mbs of data and uncompressed usr_devx.sfs contains over 300 Mbs of data. These are read only files. What unionfs does for us is that it makes a union of all the puppy files in the memory such that ro files can be used for rw. All changes that occur to the file system are stored in the pupfile.

those are great links thanks for the tips!
and yes I understand about the squashfs being much smaller
the reason I got to looking into this was in 105 I had a HD install
I backed this upto a squashfs then wiped and installed 106 and
added the kernel mod "BoostedPuppy"

I want to make a cd with the old_drive.sfs instead of
user_more.sfs and I was told that .unionfs controls the way files
are mounted and I wanted to set this file up so that everything
would work right :shock: and does anyone know how to add
cloop to the puppy and I found this interesting project maybe..........


btw the 2.2GB drive made a 546MB sqs file :D
but the docs said the largest compressed file size
is 2 gb
