comment Building Snapwm on FreeBSD (Problem of gcc and clang)?
This is what ports are: a set of configure options and if needed patch to files and/or makefile (have a look in /usr/ports/x11-wm/ctwm/files for instance). There is currently no one command way of doing it, as there is no ports for snapwm. You need to do it the hard way: configure/Imake whatever you can and/or modify the makefile to reflect your setup.

comment Building Snapwm on FreeBSD (Problem of gcc and clang)?
FreeBSD is using clang/llvm for the world and kernel. Nothing is preventing you from using gcc and gnu-make for ports or personal projects. As-long-I-remember gnu-make was named gmake on FreeBSD platform: this is hardly new.

Then what about your OS releases ? pkg version ? the exact content of your /etc/make.conf ? last time you upgraded your port tree ?

@usitesion: uname is giving information about your system. So in this case it does mean you have a 64 bit OS

comment Redhat Linux: How to know my system configuration?
I don't really see the point regarding /etc/issue: this is a user level only information message defined by the system admins (ex: legal warning for company servers).

comment How to make a custom FreeBSD distribution
Beware. An ISO fs requires some other things to properly boot. You should use the mkisofs (or another ISO making tool), as suggested by the link you gave.

comment How to make a custom FreeBSD distribution
As soon as you keep all the things in / (no other partition), then there is good chance you got something almost working (you might still need to fix a few conf files).

comment Recovering data from a failing RAID 5 setup
This is a risk assessment here: if the dying disk failed during any operation, what you prefer: having some data saved or not ?

comment Recovering data from a failing RAID 5 setup
It really depend on the RAID driver/card, but sequentially is not a simple concept for multi-head/platter disks. So sure, you would gain some time vs randomly, but that would not be x6, nor x6 less stress.
