Post subject:  KnoppMyth Fresh Install Size
(First off, I hope this is the right forum, this is actually technically pre-install question for me).

How big id KnoppMyth when freshly installed?

Reason I ask is: I am planning to have knoppmyth on a compact flash card and then have it put all the video recordings on a separate hard drive. Is there something I have to change with the setup to make this work as well? The CompactFlash slot on my motherboard is bootable and meant for things like this.

Should I get a 1 GB or 2 GB flash card for it? Should I instead try to make my own system from something like DSL-N so that it is smaller?

Thanks

My R5D1 frontend system uses about 2.5Gb of the 5Gb root partition. While not "fresh", it is a frontend-only system so it is quite indicative of what you should expect.

You probably don't want to do this, as flash media is not rated for a huge number of writes (search Google, you'll see what I mean). I assume you are planning on this system to house the database as well as the media - If so, your CF card will constantly be written to by updates to the database, logging, etc.

If this is a concern you may just consider putting the /var directory on a hard drive partition. Since this is not an option during the install it is not quite a simple thing to do.

thaimin,
what I did for a similar function was to use a cloop image of the filesystem (like is used on the installation cd) so a 1 GB flash drive was plenty big for that. Then what I did it was to do an install to an sda disk as that was what the flash was gonna' be during the boot and copy the installed tree, less a few directories like /proc, sys, dev, tmp and such (and clean out /var/log) to another place and create the full tree there. Then build the cloop of that. Had to create the booting stuff separately (initrd & such) then copy it all to the fat32 flash.
That way the cloop and the flash don't get written during the running.

Hi Dale,

Would you by chance happen to have some basic (simple) method of adding the few modules into initrd.gz needed to make a usb drive boot? Mine starts but ends up with a kernel panic. I thought somewhere in the recent past (6 months) it had been covered as a "howto" however it may have been an error in the memory cells as I have had no luck locating the post :(

With Sata and eSata becoming so readily available at really affordable prices ( $200 for 750gig! ) this might be something others could use also.

Thanks
Mike

You could also look at running a diskless frontend, that may be another option.
