what does that mean? you could put a swap file into a ramdisk, but -
sorry for saying that - this would be one of the most stupid things, i
ever heard of. :o)

this is a good way to keep the filesystem in ram, because the big
videofiles of vdr render the filesystem cache somehow useless.

CF is just IDE, you need a simple adapter, thats all. the chipset has to
be realy broken in some strange ways, if it couldn't boot from CF.

i have to disagree! journaling does not save you from data loss in any
way. it saves you from the filessystem check, thats all. if you write to
disk and switch of you will loose data, there is nothing any filesystem
on earth could do against this.

i for myself prefere booting from network and holding all video data on
a nfs server with RAID5 and UPS. lets me sleep quite well. ;-) this also
provides me with a perfectly silent VDR.

just my 2c. ...
