I found this Gentoo Realtime Guide:
http://www.gentoo.org/proj/en/desktop/sound/realtime.xml
It appear that the WIKI article need some update.
http://proaudio.tuxfamily.org/wiki/index.php?title=Realtime_%28RT%29_Kernel
1) We must include some words about the caps USE flag
2) When using realtime-lsm, or realcap with recent kernels, we must said that
the capability module must not be loaded because this will prevent
the realcap to load. (The gentoo article is not so clear here)
3) I am not sure, never tried it, but for someone using the realcap modules, it
must not be needed to compile and install the capability module because it will
never be used. The system will use realcap instead! It seams here that both the
wiki and the gentoo guide are wrong, even if this will not arm.
# lsmod|grep cap
realcap 3464 0
commoncap 3072 1 realcap
When loading the capabilty module, I get the same, but with capability instead
of realcap. And I cannot load realcap anymore, so capability is not needed at
all in that case, only commoncap.
4) When using (PAM-)rlimits, we must add that capability must be loaded at boot
time and added in autoload.
Can someone confirm or infirm the 2 last points before I made the changes.
Cheers,
Dominique
