yum -y update at %postinstall

[Luis Miguel Cruz]

Hi all,

I am trying to run 'yum -y update' at %postinstall section.
At first it seems to runs correctly, downloading the headers. But, 
suddenly it reboots, like the end of the installation.

Could be a timeout agaisnt the yum file server the reason for that reboot?

I know that yum -y update didn´t finish to upgrade the box because at 
the first boot after the installation I execute 'yum -y update' again 
and it stills downloading headers.

Thanks.
