proper permissions for /usr/src/linux

[Brian Stults <bs7452@csc.albany.edu>]

What are the best permissions for this directory.  I only ask because I
noticed that on my home machine, they were as follows:

drwxr-xr-x   15 1046     telnetd      4096 Aug  6 23:04 linux

And at work, they were like this:

drwxr-xr-x   15 1026     user         2048 Jul  9 20:19 linux

Any suggestions?  Also, what would have determined what the permissions
were by default?  The original permissions in the tarball?  Lastly, I
recall reading somewhere that some directories elsewhere should be
symlinks to something in the kernel source directory.  Perhaps
/usr/include/linux and /usr/include/asm?  Is there anything to that? 
Where would I find out such information?

Thanks.
