They may be, but the patch in the link is to C code.
perhaps a CF-brand/model specific rule could fix it, but thats not robust.

Yes, that's what I meant with 7 - if the ATA IDENTIFY data indicates the ATA
device is a compact flash device, then don't tag it as system_internal.
Since I don't have the hardware in question, any chance you can attach the
IDENTIFY data as captured with hdparm's --Istdout option? Thanks!
