This bugzilla defect would be fixed if I had the yumvar hook outlined
above.
My plugin becomes:
def yumvar_hook(conduit):
conf.yumvar["dellsysidpluginver"] = version
try:
sysid = getSystemId()
conf.yumvar["sys_ven_id"] = "0x1028" # hex
conf.yumvar["sys_dev_id"] = "0x%04x" % sysid
except:
pass
def init_hook(conduit):
if YUM_API_VERSION >= yumvars-hook-api-version:
return
# do a bunch of backwards compat stuff
