I'm getting realtime working on various distro's. It's working ok on Fedora7, and Debian Etch. On Etch, when I installed rtirq, schedutils was a dependency, and included in schedutils is chrt. Schedutils isn't on synaptic's list on Fedora 7, but when I installed planetccrma-core, which installed the realtime kernel, rtirq, and some other bits, there was no complaint when installing rtirq about the missing dependency "schedutils". Being a bit confused about this, I looked in /usr/bin, and chrt is there. Obviously some other package is providing chrt, but how do I find out which package provided it? I tried a few query options with rpm, but without success. Thanks for any help. Nigel.
