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
1. The kernel checks (effective) capabilities when performing various
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?
