server,youmightpreservetheDHCPconfigurationfiles.
Additionalpreservedconfigurationfilesmustbeaddedtothe
/etc/rsys‐user‐file‐list.cfg
file.Thisfilemayneedtobecreatedthefirsttimecustomfilesneedtobepreserved.
Whenaddingfiles,makesureeachfilenameisonitsownlinein
rsys‐user‐file‐list.cfg
andincludesthefullpath.Forexample,thesecommandsaddthexxx.cfgandyyy.cfgfilesto
thecustompreservationlist:
echo"/etc/xxx.cfg">/etc/rsys‐user‐file‐list.cfg
echo"/etc/yyy.cfg">>/etc/rsys‐user‐file‐list.cfg
