[gentoo-dev] emerge --pretend update questions.

[<jasonm@indosoft.ca>]

hi,

hopefully this will be my one and only stupid question on this list. :)

i'm trying for a better understanding of the output from:
$emerge --pretend update

when executed on my current system, i see many lines of this:
[ebuild   U] sys-apps/tar-1.13.19-r1 to /
[ebuild   U] sys-apps/sh-utils-2.0j-r4 to /
[ebuild  R ] sys-apps/watchpid-0.1-r1 to /
[ebuild N  ] app-editors/nano-1.0.3-r1 to /
[ebuild  R ] sys-apps/tcp-wrappers-7.6-r2 to /
[ebuild   U] sys-apps/grep-2.4.2-r4 to /
[ebuild  R ] sys-apps/texinfo-4.0-r2 to /
[ebuild  R ] sys-devel/autoconf-2.13-r2 to /
[ebuild  R ] sys-devel/automake-1.4-r2 to /

Q1:  what does the R stand for?  i'm pretty sure i understand N and U, and
my first guess for R would be 'remove'.

lets say i:
$cd /usr/portage/sys-apps/grep
$emerge grep-2.4.2-r4.ebuild
$ebuild /var/db/pkg/sys-apps/grep-2.4.2-r3/grep-2.4.2-r3.ebuild unmerge
$emerge --pretend update | grep grep
[ebuild  R ] sys-apps/grep-2.4.2-r4 to /

Q2: porque?

the answer to Q1 will likely explain Q2, i'm hoping. :)



thanks,
