YUM is a nice (and useful, when used correctly) tool to manage packages, using RPM as its engine. APT, the Debian alternative, has this ability, and so does YUM. YUM does not pin a specific version of a package, but rather avoids upgrading it as soon as it was marked. It remains installed, but never…
This is the error message I have seen in my Linux+Postfix+Amavisd-new system. Not only that, but Amavis has kept a copy of each message in its tmp directory, which reduced my /var size to nothing quite rapidly. amavis[21189]: (21189-01) (!)PRESERVING EVIDENCE in /var/amavis/tmp/amavis-200 80103T051116-21189 Doesn’t sound too good.

I have come across a requirement to boot a thin client on a very cheap hardware into Linux. Due to the tight hardware requirements, and the tight budget, I have decided to focus on diskless systems, which can be easily modified and purchased to our needs. Not only that, but due to the hardware configuration…
