I was trying to figure out what packages are part of system set. So I went to check /etc/make.profile and followed any parent profiles for the list of packages in packages file of profiles which make.profile inherits. Soon, I realized that it’s easier to use a script, a Bash function actually.
lsprofile() { local d l PWD cd "${1:-/etc/make.profile}" d="$(pwd -P)" l=${2:-0} echo -e "\e[$((l+1))G$l ${d#/usr/portage/profiles/}" [[ ! -f "$d/parent" ]] && return 0 while read p; do lsprofile "$d/$p" $((l+1)) done < "$d/parent" }
You can run it without argument or give it one profile file. Here is the result on the profile I used:
% lsprofile 0 default/linux/amd64/10.0/no-multilib 1 default/linux/amd64/10.0 2 default/linux/amd64 3 base 3 default/linux 3 arch/amd64 4 arch/base 4 features/multilib 2 releases/10.0 3 releases 1 arch/amd64/no-multilib 2 arch/amd64 3 arch/base 3 features/multilib 1 features/64bit-native
The first one is the profile of my system. Bigger number means longer distance ancient. You might also want to consult the manpage of Portage and emerge, also Cascading/Stackable Profiles2. I then wrote another command to list packages in packages file in those profiles:
lsprofile /etc/make.profile | while read dummy pkg; do grep '^[^#]' "/usr/portage/profiles/$pkg/packages" 2>/dev/null ; done | sorT
I think there must be a easy way to list. I did find eix --system --only-names would list, but there are some differences, those1 seem to have been removed from portage tree. emerge -pv system is another way to list.
