Could be prepman that's failing.
"Too many links" is a filesystem error, and it seems to be originating from something Portage does at the merge stage. The number of files in /opt/cuda/man/man3 is around 1k, so I wouldn't say its very excessive. Adding dev-portage to CC to see whether they can provide any insight into this.
From this is seems like a filesystem limitation or bug that could at best be worked around from the portage side (by skipping files that fail to merge): http://opengroup.org/onlinepubs/007908775/xsh/rename.html [EMLINK] The file named by old is a directory, and the link count of the parent directory of new would exceed {LINK_MAX}.
(In reply to comment #0) > >>> Installing (1 of 1) dev-util/nvidia-cuda-toolkit-3.0 > !!! Failed to rename > /opt/cuda/man/man3/.CU_DEVICE_ATTRIBUTE_REGISTERS_PER_BLOCK.3.bz2._portage_merge_.1746 Is this file a hardlink? You can get the number of links from 'ls -l' or the 'stat' command. It doesn't seem like hardlinks should cause rename to fail here, but maybe it gives a clue.

# ls -la | grep "\-rw\-r\-\-r\-\- 88" | wc -l 88 I'm not sure what to make of this, but it seems like it could possibly be of interest.
I wonder if your particular filesystem is broken. I use btrfs here, and /usr/libexec/git-core contains files that have 107 hardlinks. So, it seems that 88 hardlinks is not necessarily the maximum allowed under btrfs.
88 hard links limit would be both low, and a strange number. Is it the dev-vcs/git package that creates those links? I could try pulling that in and see what happens.
Yes, dev-vcs/git.
I already had git installed, but re-emerged, and that worked just fine. It is ofc still possible that my fs is just plain broken. Not sure what else I can say or do, aside from perhaps taking it to the btrfs mailing list.
Maybe if you `rm -rf /opt/cuda` and re-install the package then it will just work.
Unfortunately I've done that several times already. Since portage dies on the link problem, the files are left there, and unless I remove the /opt/cuda directory I get conflicts.
Is this still an issue?
I haven't done any cuda work for quite a long time, so actually I can't say. Might as well close this, until someone eventually reports it again.
Ok, thanks, closing as NEEDINFO.
