-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all
Finally I managed to get everything up and running by using regular (i.e. non busybox) versions of: * sleep * ps * xargs Hope this helps. Next steps are, not necessarily in this order: * propose patches for optional component that do not build in buildroot * create a buildroot package for xtrabackup * package and use galera arbitrator * create scripts for automating cluster initialisation and node joining (the idea is to have mariadb galera cluster working in a very unstable network) I'll let you know.
