Using NAS4Free as my centralized storage also means I use it for Git repositories. As such it would be awesome if I could do some basic stuff with Git directly from my server's bash command line.
It's possible to install packages on NAS4Free - just like on any FreeBSD - you can write pkg install -y git. However, due to file system size of embedded installation that simple solution doesn't work - it's strange how fast those memory disks fill. Yes, one could go with the full NAS4Free install instead but there's another way.
When it comes to file systems any BSD offers a lot of possibilities - one of which is unionfs. That one allows you to expand file system with the additional space while actually preserving stuff already present in directory.
To preserve the fleeting nature of embedded installation and due to sometime finicky nature of the united file system, I find it's best to have a fresh directory for every boot, followed by mounting of fresh overlay file system:
rm -rf /mnt/.unionfs 2> /dev/null
mkdir -p /mnt/.unionfs/usr/local
mount_unionfs /mnt/.unionfs/usr/local /usr/localNow installing Git actually works:
pkg install -y gitOne could optionally also set Git configuration, especially user name and e-mail:
cat <<EOF > /root/.gitconfig
[system]
autocrlf = false
[core]
pager = less
whitespace = cr-at-eol
[user]
name = Charlie Root
email = root@my.home
EOFIf all this is placed in System, Advanced, Command scripts, it'll get preserved with reboots.
