[arch-general] systemd transition on virtual server - help needed

hi list, i am running an arch server (x84_64) inside a virtual private server. now that systemd smoothly comes to be standart, i would like to understand, how this affects my machine. as this is a vps, i have no control over the running kernel, which is a 2.6.36.4-vs2.3.0.36.39-netcup atm. (netcup is a german webhosting provider). also i do not know much about the virtualisation machinery running there. as this is a server used for productivity, i would like to understand whats happening to it, to keep maintenance downtime at a reasonable low level. at what point will i (propably) get in trouble because of systemd, when (if ever) will i be unable to boot with this machine if i keep updating? thanks for helping suggestions. georg
