[gentoo-user] Safety/wiseness of moving stray files from /etc/env.d

[gentoo-user] Safety/wiseness of moving stray files from /etc/env.d

[Jorge Peixoto de Morais Neto]

Hi. Some of my environment variables are screwed up
/etc/env.d $ echo ${MANPATH}  
/home/jorge/.gentoo/java-config-2/current-user-vm/man:/usr/local/share/man:/usr/share/man:/usr/share/binutils-data/i686-pc-linux-gnu/2.18/man:/usr/share/gcc-data/i686-pc-linux-gnu/4.1.2/man:${MANPATH}:/opt/sun-jre-bin-1.5.0.06/man:/etc/java-config/system-vm/man/

There is a '${MANPATH}' inside "${MANPATH}", and besides that
"{MANPATH}" references the long obsolete sun-jre-bin-1.5.0.06

Also
/etc/env.d $ cat 05gcc-i686-pc-linux-gnu 
MANPATH="/usr/share/gcc-data/i686-pc-linux-gnu/4.1.2/man"
INFOPATH="/usr/share/gcc-data/i686-pc-linux-gnu/4.1.2/info"
LDPATH="/usr/lib/gcc/i686-pc-linux-gnu/4.1.2:/usr/lib/gcc/i686-pc-linux-gnu/4.2.2"
PATH="/usr/i686-pc-linux-gnu/gcc-bin/4.1.2"
ROOTPATH="/usr/i686-pc-linux-gnu/gcc-bin/4.1.2"
GCC_SPECS=""

LDPATH references gcc-4.2.2, which is no longer installed
(for several months, in fact).
And there is both a 05gcc-i686-pc-linux-gnu file and a gcc directory in /etc/env.d

Also, some files in /etc/env.d are suspiciously old:

Also, there is both a 05binutils file and a binutils directory.
Inside the binutils directory, there is this

/etc/env.d $ ls -l binutils/

Is it safe/wise to move 20java and 05gcc-i686-pc-linux-gnu to a backup directory? How about binutils/config-i386-pc-linux-gnu? How about the blas, cblas and lapack directories (I have long ago unmerged the corresponding packages)? They contain only this:

/etc/env.d $ find blas cblas lapack -type f -exec ls -l {} +
-rw-r--r-- 1 root root 95 2008-02-16 15:59 blas/lib/config
-rw-r--r-- 1 root root 95 2008-02-16 15:59 cblas/lib/config
-rw-r--r-- 1 root root 95 2008-02-17 14:16 lapack/lib/config


/etc/env.d $ for file in  {blas,cblas,lapack}/lib/config; do echo "${file}:"; cat "${file}"; echo; done
blas/lib/config:
# Configuration file for eselect
# This file has been automatically generated.
CURRENT="atlas"

cblas/lib/config:
# Configuration file for eselect
# This file has been automatically generated.
CURRENT="atlas"

lapack/lib/config:
# Configuration file for eselect
# This file has been automatically generated.
CURRENT="atlas"

Well, since you are backing them up, I don't see much harm since you can
move them back once you see that something broke. When is the last time you
did an etc-update? What running env-update?

My fear is that something may break and I not realize; or it may break something
2 months from now, when I wouldn't associate the breakage with my messing with
/etc/env.d. I am afraid of breaking the system after doing enough times already.

I use dispatch-conf every time Portage warns me to update configuration files.
Just to make you happy, I have just run etc-update followed by env-update.
Nothing changed.

Speaking of env-update, see my /etc/ld.so.conf, and how it is screwed up:
$ cat /etc/ld.so.conf 
# ld.so.conf autogenerated by env-update; make all changes to
# contents of /etc/env.d directory
/usr/local/lib
//usr//lib/opengl/xorg-x11/lib
/usr/i686-pc-linux-gnu/lib
/usr/lib/gcc/i686-pc-linux-gnu/4.1.2
/usr/lib/gcc/i686-pc-linux-gnu/4.2.2
/usr/lib/nspr
/usr/lib/nss
/opt/sun-jre-bin-1.5.0.06/lib/i386/
/opt/sun-jre-bin-1.5.0.06/lib/i386/native_threads/
/opt/sun-jre-bin-1.5.0.06/lib/i386/xawt/
/opt/sun-jre-bin-1.5.0.06/lib/i386/server/
/opt/firefox
/usr/games/lib


There is no /usr/lib/gcc/i686-pc-linu/usr/lib/gcc/i686-pc-linux-gnu/4.2.2
and no /opt/sun-jre-bin-1.5.0.06. These are erroneous entries.

Has this happened with other people? Does Portage leave stray files
behind in /etc/env.d?
