Code Issues Releases Activity

Try to make 'uname -a' look more like it does on Linux:

Browse Source 
- cut the version string at the newline, suppressing information about
   who built the kernel and in what directory.  Most of this information
   was already lost to truncation.

 - on i386, return the precise CPU class (if known) rather than just
   "i386".  Linux software which uses this information to select
   which binary to run often does not know what to make of "i386".
