No. The entries in the sysname list are always tried in order. The idea
is that you list more-specific names before less-specific ones, and
more-desirable names before less-desirable ones. So you can set the
sysname list to something like
i686_linux26 i586_linux26 i386_linux26 i386_linux24 any_linux common
And get the most-appropriate binary for your system. If your system is not
an i686, leave off the first name, and so on.

No; you have to use 'fs sysname' to set the sysname after afsd has started.
The usual approach is to do this in the same script that loads the kernel
module and starts afsd. On some platforms, the provided startup scripts
have a variable you can set to control what they set the sysname to.
