Currently only can disable coloring or just capability coloring, which will disable the capability lookup. This was seen to significantly impact performance: $ mkdir testcap $ cd testcap $ seq 10000 | xargs touch $ time ls --color -l >/dev/null real 0m0.150s $ time LS_COLORS=ca=: ls --color -l >/dev/null real 0m0.116s Though the overhead is decreasing over time: Fedora 8 = 30% Fedora 15 = 24% Fedora 20 = 14% So I'm leaning towards leaving this enabled now in --long mode thus allowing to set the permissions flags appropriately. So what to set? Well we only have a single byte to play with. Currently we have '.' meaning only SELinux, and '+' meaning anything else. So I'm thinking we should also have capabilities significant for outputting the '+'. This is also tracked at http://bugs.debian.org/756712 thanks, Pádraig.

Been using unicode for 10+ years on my file systems (often with many compat issues), but have only recently started to see more widespread usage of them on the net...but felt wasn't fully enough supported to use as an indicator in ls...

Yes, in general colors aren't a good mechanism to indicate permissions. I prefer to highlight portions of the permissions string, which is more direct and obvious. See http://www.pixelbeat.org/scripts/l But we have to be a bit careful adding to the permissions string, for compat reasons etc. I do like the idea of ^ (hat) => cap. You could even be fancy and use combining hat (\u0302) so as to not take up any more place, though combining char support is not currently supported well enough to allow that I think. We'll consider it, thanks, Pádraig.
