It is certainly possible, but you'd have to skip the kernel
upgrades, and be very careful. init will get upgraded on disk,
but the running one in memory will be older. This should only be
attempted in single user mode because the C libaries will get
updated as well as all critical behind the scenes stuff like
ld.so, etc..
If the system is running while this is going on, there is a high
likelyhood that things will explode.
Since the system is effectively offline in single user mode, you
might as well do the upgrade normally however.
