I have a server at my house that runs Ubuntu server 14.04.3 LTS right now.
george@sf1:~$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 14.04.3 LTS Release: 14.04 Codename: trusty
I also rent one from OVH that supposedly runs the same thing; I selected 14.04 LTS when I ordered it.
george@daisy:~$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 14.04.3 LTS Release: 14.04 Codename: trusty
Now... why are there minor differences between the two? The first thing I notice is different kernels:
george@sf1:~$ uname -r 3.19.0-49-generic george@daisy:~$ uname -r 3.14.32-xxxx-grs-ipv6-64
Why are they not on the same kernel version, and what is the difference between the two? What are those letters after the version on daisy (instead of generic)?
Also, this may be totally related, but in using common unix tools like
ps I get different outputs on each machine. So on sf1,
ps -ef gives me all processes on the system whereas on daisy it gives me just processes that my current user is running. Does the different kernel version affect the utilities installed on it?
Is it possible to update the kernel on daisy? Would it change anything?
