Hi, i'm looking for a Linux equivalent of Windows XPe Enhanced Write Filter, which basically will write all system changes to a ram disk which can, if required, be committed to disk by the user via a write utility. If power is removed and changes not committed to disk all changes will be lost.
The reason i am after this is because i wish to run Linux on compact flash. I have been messing around with pfsense firewall but it transpires i need something a bit more flexible, a Linux based install which can run on compact flash with minimal disk writes to compact flash to ensure the CF card doesn't die, but also with the ability to update the file system and install custom packages, install from source etc.
It would be ideal to have BSD (ok not linux but dont want to get OT here), CentOS or similair running on CF card, i know people talk about make the file system Read Only but then that has issues with certain packages in the system that need write access, would be nice if these changes could be committed one as off writes.
Have searched for a compact flash enabled distribution but with the benefits and flexibility of installing packages via apt-get etc but cannot find one, hence my idea that a write filter driver which could sit in between the CF card and IDE driver would be great... then i would get the benefit of both worlds.
Any ideas? Any recommendations to a an existing CF based linux distro would be great, but as this is for a number of router boxes that need to be up and running in a short space of time i dont want to spend too much time on the development side of it. Plug and play write filter driver would be best.
Many thanks in advance,
Chris
