[gentoo-user] Checking sanity of system...

[gentoo-user] Checking sanity of system...

[meino.cramer]

Hi,

this is no security issue in sense of attacks...it is related
to the consistency of the system.

Simple question (and may be complicate to answer... ;) )

How can I check, that my Gentoo system is uptodate, consistent 
and sane?

Best regards,
mcc

I think this is what you want.  man glsa-check  I don't use it so you 
will have to read or wait until someone who uses it comes along.  No 
real clue how it works.

I hope that helps and is what you are looking for.

emerge --sync && emerge -uDN world

Define "consistent" and "sane".  Those words don't say anything, really.

You may also want to run revdep-rebuild as well.  If you are talking 
about your packages being "sane".  That should catch anything that has 
broken links or something else that leads to a package needing to be 
recompiled.

Ok...

Consistency: Following each logical branch of each logical tree of control relationship,
which is for example but not only the tree of dependancies, will end in a
leave. These are the control paths.

Sane: Following each logical branch of each logical tree of data
relationships. which is for example but not only the interaction of scripts under
/etc, will end in a leave. These are the data paths.

Hi Dale,

As far as I can understand the man-page, glsa-check is a tool to check
security settings in the system: _G_entoo _L_inux _S_ecurity
_A_visory.
I didnt know of this tool before so it is a goog hint anyway, but for
the moment I want only check, whether the system is not cleanly
setup/installed/updated in the sense of "it is working well" ;)

Best regards,
mcc

Hi Dale,

revdep-rebuild is currently running! :)

This was the only tool I knew before posting my question here :)

These are very abstract things you speak of.  But I guess it boils down 
to "are there bugs in my system."

Yes, there are.  All software has bugs.  There is a tool to check 
whether there are bugs: you.  You use the software and check whether it 
works correctly or not.

For anything more specific, you also need to be more specific with your 
questions. :)

When I do my updates, I always do the following:

eix-sync   # This does my emerge --sync for me and updates eix since I 
use it sometimes for the FAST searches

emerge -uvDNa world   # My system is set up so that world includes 
system so this catches everything including deep dependencies (D) and 
changes of USE flags (N).

I then check USE flags and anything else that may be odd.  If I need to 
change something, I answer NO and repeat until I get it like it should 
be.  After emerge finishes:

emerge -p --depclean  # I run that about once a month or if I know 
something is unneeded and should be removed.  If it looks sane, I rerun 
without the -p.  You could use -a I guess.

revdep-rebuild -i  # This makes sure nothing is broken and I run it each 
time after the emerge world whether --depclean is ran or not.  It 
sometimes finds something broke and fixes it so I figure it is safer to 
run it and it do nothing than to not run it and something be broken.

One more optional thing to run, python-updater.  If I see python being 
updated, I run that too.  Note:  Python 3 should be popping its head up 
if it hasn't already.  If it does, do NOT switch the system to it.  A 
lot of packages do not work with it yet.  If you switch to it, you can 
keep the pieces if it breaks.  Sane thoughts did not prevail on -dev so 
you either have to mask it locally or it will be there basically doing 
nothing.  Don't ask me why they did it.  I was against the idea myself. 
< shrugs >

That's how I do it and my little rig runs pretty good.  I do have 
hiccups on occasion but everyone does eventually.

Hi,

Every Update:
emerge --sync && emerge -uDN world
--> Read the Packagemessages for Instructions.
etc-update    # Merge new Configfiles
revdep-rebuild    # Identify broken libraries

From time to time:
emerge --deplcean (-p) && revdep-rebuild    # Delete old packages and
sort out the resulting broken packages
eclean distfiles    # Delete the old source-packages in your distfile repo.

Regards,
Norman

and aditionally from time to time:

eix -u
(packages  which  have  at least one slotted version installed which is not 
the best version within that slot)

and 

eix-test-obsolete -d
(display missing packages or packages with obsolete 
entries in /etc/portage/package.* )

Check for viruses, lookout for SMART data, and filesystem inconsistencies, check 
temperatures, check log files, listen to fans... there are many levels where a system could fail.
