1 Hello
3 Background:
4 As a minimalist I'm trying to ferret out the differences in some of the more
5 minimal profiles versus potential embedded profiles, across several
6 different architectures: (arm32, arm64 x63_32 x86_64 ppc etc). I am also
7 quite curious to find a tool that will clearly list the complete set of
8 packages a given (eselected) profile will yield and the best ways to
9 customize that list of minimal (critical) packages.
13 So in /etc/portage/profiles, we have lots of good information. For example
14 the 'base' dir currently lists 77 packages found in most profiles (?). The
15 '/usr/portage/profiles/arch.list' dir lists not only the recognized arches
16 but also "Prefix Keywords". I'm not exactly sure how all of this profile
17 stuff works; who decides what's (packages) in and out, package_masks etc etc.
20 So my questions related to how does gentoo actually determines the exact
21 list of programs that are minimally installed, with the specific
22 arch and the profile selected? In previous times, I just put USE='-*' in the
23 make.conf file and built upwards from there. Still there were baseline
24 packages in the most minimal of stage based gentoo builds. I'm looking for a
25 current approach to bridging between a baseline default profile (for amd64
26 that would be: [1] default/linux/amd64/13.0 *) and an embedded amd64
27 profile (if one currently exist? How do I find the potential profiles for
28 say another arch (ppc for example), from an amd64 based gentoo system?
29 Tools? Recommended scripts to review?
32 'eselect profile list' currently shows 21 amd64 choices:
34 [1] default/linux/amd64/13.0 *
35 [2] default/linux/amd64/13.0/selinux
36 [3] default/linux/amd64/13.0/desktop
37 [4] default/linux/amd64/13.0/desktop/gnome
38 [5] default/linux/amd64/13.0/desktop/gnome/systemd
39 [6] default/linux/amd64/13.0/desktop/kde
40 [7] default/linux/amd64/13.0/desktop/kde/systemd
41 [8] default/linux/amd64/13.0/desktop/plasma
42 [9] default/linux/amd64/13.0/desktop/plasma/systemd
43 [10] default/linux/amd64/13.0/developer
44 [11] default/linux/amd64/13.0/no-multilib
45 [12] default/linux/amd64/13.0/systemd
46 [13] default/linux/amd64/13.0/x32
47 [14] hardened/linux/amd64
48 [15] hardened/linux/amd64/selinux
49 [16] hardened/linux/amd64/no-multilib
50 [17] hardened/linux/amd64/no-multilib/selinux
51 [18] hardened/linux/amd64/x32
52 [19] hardened/linux/musl/amd64
53 [20] default/linux/uclibc/amd64
54 [21] hardened/linux/uclibc/amd64
58 But looking here at the files and directories ( ls /usr/portage/profiles)
60 I see an organization structure that differs from the profile listing
61 semantics. So is there a script(s) that shows me what is being read from
62 the directory tree that yields those 21 choices? It seems a bit convoluted
63 to me, but I could easily have missed the documents that organize and
64 discuss such details? Or at least a listing of the scripts that build these
65 profile lists? Or is this adhoc?
68 The next thought is how then to best (succinctly) determine the complete
69 list of packages that will be pulled into any given (arch) profile. Is this
70 a fiefdom situation where those devs that maintain that arch (tongue in
71 cheek) quasi-use these scripts, config files and the /usr/portage/profiles
72 tree structure, consistently or as they wish? I'm not looking for emotional
73 responses, just clarity on where we are.
75 Finally. What if I want to "roll my own profiles"; should I just build on
76 one of the minimal ones or create something anew that exists only on my
77 systems? If the latter, any insight or examples would be keen information.
78 Yes, I know messing with the 'will of the dev(masters) will put me on a
79 course of little help; but I just see a better way that I want to experiment
80 with the profile pieces that are integral to my efforts. My main goal is to
81 bridge the gap between what is embedded (truly minimalistic)
82 and a minimized (via the profile) gentoo system.
85 TIA,
86 James
