additional notes

a few more packages worth mentioning

#ksh93 \
#lynx \
#lftp \
#git \
#cyrus-sasl \
#htop \

#jfsutils \
#iptables nftables \

#gnutls \
#dhcpcd \       # no need as we have dhclient from the dhcp package
#bonnie++ \
#rsync \

and those are pretty essential for system and network troubleshooting

bind
traceroute
nmap
htop
iftop
nload
# ntop has too much deps incl. X
