RE: [Ltib] jffs2 packing question

[Krzysztof Stankiewicz]

What I thought was odd was that I have a 33mb jffs2 file, I mount it, then pack it into another jffs2 file. and I end up with 170mb file.
My 33mb jffs2 file should be already pruned..


Also what I know files in /bin directory should all link to one busybox elf and be negligibly small. But in my case they're all 1mb.
I also read that jffs2 doesnt support links....it instead makes copy of original for each link...so Im thinking my original jffs2 somehow
got around this..

AM I onto something or should I just go with your original suggestion?

You will notice that LTIB does some pruning of the ltib/rootfs tree (copies to ltib/rootfs.tmp) when it generates the file. If you are manually generating rootfs.jffs2 file, you need to do your own pruning.

What gets pruned by LTIB is configurable under " --- Target Image Generation"...

Here's the spew I get from ltib. The jffs2 file is actually around 50-ish meg in my case..

Processing deployment operations

==================================

making filesystem image file

staging directory is /home/bl/ltib/rootfs.tmp

removing the boot directory and files

removing man files and directories

removing info files

removing /usr/src directory

removing /usr/include directory

removing /usr/share/locale directory

removing static libraries

removing target rpm database

stripping binaries and libraries

WARN: /home/bl/ltib/rootfs.tmp/sbin/ldconfig statically linked

WARN: /home/bl/ltib/rootfs.tmp/sbin/insmod.static statically linked

WARN: /home/bl/ltib/rootfs.tmp/sbin/sln statically linked

Filesystem stats, including padding:

    Total size            = 135592k

    Total number of files = 5013

Saving temporary staging directory: /home/bl/ltib/rootfs.tmp

Hi guys,

I have a rootfs.jffs2 file its about 32meg.
But when it is deployed its about 240mb.
Also if I mount it on my laptop into a subdir, I can see its 240mb.

How do I pack it back into 32mb? when I use
/opt/ltib/usr/bin/mkfs.jffs2 -n -r rootfs_working -m size -e 16 -o /tftpboot/rootfs.jffs2
I end up with a file thats 170mb..

Whats the trick?
