Buildroot is pure awesomeness for maintaining the build of a GNU/Linux based operating system. However, during my ventures I’ve had to keep private code private so use a git repo behind ssh. There is a way to achieve this with Buildroot but it is undocumented:
LIBFOO_SITE_METHOD = git
LIBFOO_SITE = ssh://email@example.com/group/repo.git
LIBFOO_VERSION = v1.01.a
On the first line we have to set the method to git as the auto detect won’t work on SSH
The second line contains the git repo as it would be defined if using git via ssh accept prepended with ssh:// and the the colon that is normally between the end of the FQDN and the location is replaced with a slash.
Line 3 can be a tag, branch or commit hash.
I am not sure if line 2 is correct in all cases but it works for me.
I use windows live writer to create most of the blogs posts here. I use the code formatter plugin to show code in blog posts. You can get it from here:
With an already functioning TFTP server and PXE boot environment for Debian 7 network install with files also being served over http from the same path as the TFTP server it is straightforward to boot UrBackup over the network. The same method applies to many Linux live cds.
Adding to pxelinux.cfg/default
Add the following to your default fiile in pxelinux.cfg
Menu Label ^UrBackup
append initrd=initrd.img boot=live config username=urbackup toram fetch=http://tftp/urbackup/filesystem.squashfs
Ensure you change the hostname to the ip or host of your tftp server and that you are serving the squashfs file over http. Note that the initrd and vmlinuz are from the debian network boot sources.
