Re: [OpenAFS] Re: afsd.fuse usage?
Hi, Dunno. My fuse ukernel is pretty old, and worked. From the src, afs_root() is failing. Might be an issue with the supplied dirs? I would at this point build with full debugging and trace into it.

Yeahbut, I mean, how do you specify which client to talk to? There could be several on the machine. I don't think straight rmtsys would work because of that, but I guess the same AFSSERVER mechanism could be used to specify? Like, have a syntax that instead says talk to the cm mounted at X instead of a host name. From there I was thinking communicating using xattrs, but I don't know. we could add alternate port support for rmtsys, and then you have a virtual file in the top of the mounted (fuse) afs, which specifies localhost:port export AFSSERVER=`cat /path/to/my/afs/.AFSSERVER` and then just do stuff. the xattrs method is not a bad idea either, i wish the GSoC project along those lines had gotten on further. -- Andrew Deason adea...@sinenomine.net ___ OpenAFS-info mailing list OpenAFS-info@openafs.org https://lists.openafs.org/mailman/listinfo/openafs-info -- Derrick ___ OpenAFS-info mailing list OpenAFS-info@openafs.org https://lists.openafs.org/mailman/listinfo/openafs-info
