CFSworks's must-have Debian packages
# These are the packages I tend to bring with me onto every Debian system I administer,
# and are therefore the packages I tend to install first thing in a fresh Debian system.
# Obviously, not all of them are necessary for a specific environment, so this list
# serves more as a baseline to pick from than a list of requirements.
# List is sorted in ascending order of "risk" to the system vs. likely usefulness
# (i.e. how likely it is to be abused by an attacker and whether it's more likely to
# help a sysadmin than create a security nightmare)
