Images folder, what is that for?

Post#1 by wread » 23 Dec 2011, 23:00

If you open the "images" folder in 32-bits Porteus you will find a footprint of all extracted *.xzm files (that's what I thought, as of today).

Now, in the 32-bit versions of KDE4 I have made, I put an empty folder "images", but after starting the system, the folder is still empty.

How does it work, in fact? Does Porteus needs images to shut down properly? Who creates those footprints? and last, not least, what am I missing that I don't get those footprints created?

Or am I wrong at all? :%)

EDIT: I may ask a newbie question, or may I not?

I believe it serves as a mount point, or, rather, a parent directory to hold all the mount points for the activated xzm modules. I imagine they must be mounted there in order to be overlaid into aufs. The answer must be lurking in linuxr and/or liblinuxlive. I usually access 'images' at /mnt/live/memory/images, and everything from xfce shows up there -- maybe simply symlinking your folder there will do the trick?

I know fanthom or brokenman will have a much more thorough answer...but I wanted to post anyway and see if I'm right :)

Thanks for asking, you've piqued my curiosity, too!

Now then, what about /changes/xino ??
Please take a look at our online documentation, here. Suggestions are welcome!

Ahau, you hit the ball out of the park!

I must explain: the triple-boot systems I have built (LXDE, Trinity, KDE4) have the path /porteus/images only for LXDE and Trinity. I have put an "images" folder in /474/porteus/images which is a wrong link that of course stays empty. When I run KDE4, the folder /porteus/images gets populated with the footprints corresponding to KDE4 as it should be!

Thanks for the tip.

I am also wondering whatś the use of /live/memory/xino. For sure fanthom has the right answer!

Regards!

@wread
this is the folder where 'external inode number bitmap and translation table' are kept. for best user experience xino is always placed on tmpfs (fastest, frequent read/write operations has no impact on flash media), even when changes= cheat is used. xino files are unlinked (always hidden) but they are there and used by aufs very often.

more info about xino can be found in the manual page for aufs:

Please add [Solved] to your thread title if the solution was found.

I secretly think fanthom is part man part machine sent back from the future ... (where of course Porteus is installed on everything)
