An SCM is not a replacement of a backup.

In my workplace environment, the equivalent of the above
/usr/src/rootstuff is accessible throughout the networked
machines (mostly NFS mounted); for things that needs per-host
customization, we do not have /usr/src/rootstuff/etc/hosts but
keep /usr/src/rootstuff/etc/hosts.in as the source, and Makefile
customizes that into a form suitable for installation for each
machine.  Especially useful is vfstab.in --- a single source
builds fstab for local mounting and nfs exports, while other
machines have mountpoints and project symlinks pointing into
location automounted from that machine with disk, generated
automatically.  This does not match typical "package" use.
