Tbh, I totally disagree here. LFS is nice to get started when learning
That's why I said, it may help you.
but for a critical servers you need some sort of package
management and well maintained repository.
And then? apt-get update; apt-get upgrade; with cron every hour?
You are kidding.
You cannot spend your time
updating and compiling software and fixing patches every time there is
an update whilst the next zlib/ssl exploits are floating
around the net.
I have to spend the time, and if my server is REALLY critical, I will have
to. Ans most of the time, my team is faster than debian.
One thing I do agree with is creating a custom kernel suited for your
Suited for the hardware and implementing a couple of security features.
I think the basis for a mission critical server is its hardware. Make
sure you select hardware wich is well known and widely
supported for the
distro you intend to run. Don't choose exotic hardware raid cards just
because they might work good. Choose the one wich has the
The same goes for all other hardware offcourse.
The hardware can do a lot for availability, of course, but nothing for
security (except physical security)
Now for the distro to choose there is a wide variety which
can be used.
Whatever your needs are, pick a distro with good support. Depending on
what kind of server you need to run choices could be (but are not
limited to) Openbsd for firewalls/security, Solaris for stability and
Ever tried to customize your Solaris-kernel?
Debian for feature richness or Redhat Enterprise for a large
hardware base and its support.
If pure stability is the only factor in my decision I would go for
Openbsd or Solaris and choose hardware which is 'known-to-be-good' for
