When I asked the question below a while back, I got no response. Is there really noone who can say anything about the future of capabilities?
Cheers
Michael

Gidday,
What are the current status and future of capabilites? There seems to be no up-to-date information on this anywhere.
It seems capabilities have been partly implemented since 2.2. That is to say:
1. The kernel checks (effective) capabilities when performing various operations.
2. System calls are provided to raise and lower capabilties
What's still missing in 2.4, as far as I can see after reading the sources, is the ability to set capabilities on executable files so that a process gains those privileges when executing the file. I recall seeing some information somewhere saying this wasn't possible / wasn't going to happen for ext2. Is it on the drawing board for any file system?
Thanks
Michael
