I have been using Debian and NetBSD systems for a long time, and I have got used to do binaries upgrades for the base system and for packages (using pkgin with NetBSD)
Now the NetBSD kernel does not work so well with the VPS provider, but FreeBSD is a supported option there, so I am thinking to make the switch.
I have seen that binary upgrades from the base systems seem reliable with freebsd-update, how reliable is this for binary packages ? I mean reliable, that you would trust it to be done on a server running Apache with php, python, a DNS server without too much downtime.
