:That was the sucking in of the /etc files. I'm referring to the
:following in rc.diskless1 where you check for host-specific files,
:followed by network, then a default config:
:
: if [ -d /conf/${bootp_ipa} ] ; then
: cp -Rp /conf/${bootp_ipa}/etc/* /conf/etc
: elif [ -d /conf/${bootp_ipbca} ] ; then
: cp -Rp /conf/${bootp_ipbca}/etc/* /conf/etc
: else
: cp -Rp /conf/default/etc/* /conf/etc
: fi
:
:I've found that one can reduce a lot of common file duplication by
:reversing that logic, going after "default" first, then
:"network-specific", finally followed by "host-specific" files:
:
: if [ -d /conf/default/etc/ ]; then
: cp -Rp /conf/default/etc/* /conf/etc
: fi
:
: if [ -d /conf/${bootp_ipbca} ] ; then
: cp -Rp /conf/${bootp_ipbca}/etc/* /conf/etc
: fi
:...
Oops. That was broken allright. It's definitely correct to
copy the files in reverse order so the network files override
the defaults, and the per-host files override the network files.
