Many times when I install a program or modify a system setting and I'm being asked to restart the computer, I get annoyed. Do you have the same feeling?
I'm 50/50 on this. If I was sitting in front of the computer wanting something to finish and it tells me to reboot then yes, but if I just set it going while at the computer and then walk away I don't care.
It doesn't bother me. I would prefer an application to actually completely install instead of leaving out the parts it can't install due to resources that are currently in use by the system. But I guess that's just me...
for a regular pc i don't mind a reboot, angry when a server needs to reboot. If you want to move to linux get a version like oracles which has ksplice and doesn't require and reboots.
