Creating a custom preservation list

Otherfilesmayneedtobepreserved.Forexample,onanATCA‐2210SCMrunningaDHCP

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

Savethefilewhentheadditionsarecomplete.

Preserving other files and configurations manually

Mostfilesoutsideof/etccannotbepreservedbythetools.Considerwhethertomanually

savethefilesyouhavecreate doutsideof/etc,suchastheDHCPleasesfile.

Topre serveconfigurationfilesoutsidethe/etcdirectory,addthemtothe

/rsys/onboot.data/overlaydirectoryandreferencetheminthe/etc/rsys‐user‐file‐

list.cfg

file.

Analternativemethodformanuallysavingfilesistocopythefilestoaremoteserver(using

FTP,SFTP,orTFTP)beforeupdating.Copythembacktothemoduleaftertheupdateis

complete.

Note:UseFTPorSFTPtoachievethe bestperformanceandreducetheupdatetime.

Forthe
