Do hosting companies ever upgrade outside of the standard packaging
system of their OS vendor?
Do they ever upgrade OS version on a production server?
I thought they would not exactly because of the above risk but I am
not in the hosting
business and in the past 8 years I think I only used full servers not
So this is just my guess.
I was impressed by the "stack" presentation of JT on YAPC but IMHO the "stack"
of what you supply will greatly depend on all kinds of things.
On one hand for some people it is ok to supply only their own code, on the
other hand others will go as far as wanting to supply "appliances".
That is everything including the hardware.
In between there are those who supply all their non-standard perl dependencies
