Hi, i'm looking at OpenWRT and moving away from DD-WRT. Under DD-WRT i wanted to edit some scripts (ip-up for the pptp client) but as  they exist in /tmp they are only in memory.

If i move to OpenWRT will i get a /etc/ directory like a normal linux system that is saved to flash, i have used embedded snapgear linux before but i dont want to rebuild the source just to edit scripts. Will OpenWRT be more flexible in this regard?

thanks for the advice, i look forward to becoming a OpenWRT user

Sounds like you'll love OpenWrt.  In short, RO (squashfs) and RW (jffs) filesystems automagically behave like you were editing a harddisk.  Even better, the RO version of any file is still available (in /rom) as is a nice snapshot of all added/edited files (in /jffs).  If you have 4M flash it'll seem huge compared to DD-WRT.

OpenWrt is basically designed to look like a pc running debian.

The filesystem is a Copy-On-Write (COW) scheme, composed of two filesystems, the readonly squashfs filesystem in /rom, and the writable jffs2 filesystem on /jffs, combined into a virtual /. Any attempt to open a file with write permissions will result in the file being created or copied to the matching directory under /jffs, all transparent to the user.

Thanks guys

i have had some issues with dd-wrt and pptp client being stuck in stone and almost unmodifiable, i want to mess around with the scripts directly.

As a development box can i bung an sd card onto my unit and get megabytes of flash, is this supported on OpenWRT? I just read:

- mount_root mounts the jffs2 partition (/jffs) and combines it with the squashfs partition (/rom) to create a new virtual root filesystem (/)

:3D i hope that means what i think it means :3)

One final thing, how easy is wifi to configure via scripts? I wish to run wireless client bridge to my lan as per my dd-wrt box.

I will need to build blueprint units at some point, but then i can go and recompile the build and create a custom image, in the meantime at least i can develop with ease!

Thanks
