correct

not quite ... while this may be true in the glibc world (being able to select 
the lowest compat linux ABI level), uClibc does not provide this atm ... so 
uClibc can only be safely used on whatever version of linux you compiled 
against, but in practice you can usually get away with it across micro 
versions of the kernel

it does provide the option to build the kernel for you now (although ive never 
used it myself)
