rlm@1 1 The point of this system to to
rlm@1 2
rlm@1 3 1. Determine the provenence of every file on my system.
rlm@1 4 2. Always have an "undo" button.
rlm@1 5
rlm@1 6 These criteria have evolved from my frustrations
rlm@1 7 with my previous LFS system.
rlm@1 8
rlm@1 9
rlm@1 10 User expreience:
rlm@1 11
rlm@1 12 Suppose I want to install emacs.
rlm@1 13
rlm@1 14 here's a sample terminal session
rlm@1 15
rlm@1 16 $ pkg emacs "a text editor"
rlm@1 17 > creating user emacs.
rlm@1 18 > cd /pkg/emacs
rlm@1 19
rlm@1 20 $ wget http://emacs.com/emacs.tar.bz2
rlm@1 21 > downloaded emacs.tar.bz2
rlm@1 22
rlm@1 23 $ unp emacs.tar.bz2; cd emacs; configure;
rlm@1 24 make install;
rlm@1 25 > install stuff..
rlm@1 26
rlm@1 27 $ hg st
rlm@1 28 > a bunch of files are added
rlm@1 29
rlm@1 30 1. Say I don't want emacs after all.
rlm@1 31 $ hg purge; hg revert --all
rlm@1 32
rlm@1 33 2. Complete emacs instilation
rlm@1 34 > hg addr; hg commit -m "emacs."
rlm@1 35
rlm@1 36 (this commits as the emacs user)
rlm@1 37
rlm@1 38 3. can examine provenance of information
rlm@2 39 $ pkg-report emacs
rlm@1 40 > package emacs owns the following files:
rlm@1 41 > emacs
rlm@1 42 > man/emacs
rlm@1 43 > ....
rlm@1 44
rlm@1 45 4. see all the commits that the "emacs" user made.
rlm@1 46 $ pkg-history emacs
rlm@1 47 > <filtered mercurial log>
rlm@1 48
rlm@1 49 5. remove a package in its entirety
rlm@1 50 $ pkg-remove emacs
rlm@1 51 > removed
rlm@1 52 > <list of files>
rlm@1 53
rlm@12 54 the root-level mercurial repository is owned by
rlm@12 55 hg-commiter:hg-wheel, where hg-committer is the
rlm@12 56 user for which the "hg" alise for each package
rlm@12 57 user is setuid.
rlm@1 58
rlm@12 59 high level users can be added to hg-heel to
rlm@12 60 administer the root-level mercurial repsitory,
rlm@12 61 which will allow them to do things like hg log, hg
rlm@12 62 purge, etc.
