I've used these to set up a NFS root area for a bunch of servers, but
each server has a local disk where I put /var, swap, and a /local
mount point for things that need to be accessed a lot. I found
rc.diskless1 was fine, but I needed to hack up rc.diskless2 pretty
thoroughly for my own situation. It provided a good template, though :)
However, there was one area that I thought you did kind've backwards.
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
if [ -d /conf/${bootp_ipa} ] ; then
cp -Rp /conf/${bootp_ipa}/etc/* /conf/etc
fi
The idea of this being that most /etc files go into "default", and
only overrides go into the "network" and "host-specific" directories.
Would folks support and agree to a change like this?
