[gentoo-user] Unable to login to gentoo

[-- Attachment #1: Type: text/plain, Size: 417 bytes --]

Installed Gentoo Linux with KDE. Worked on it for some days without any
problem. The disk became full (now deleted some files downloaded to my
documents to get 1.5Gb free space). Now i can't login to Gentoo. The login
screen appears when username and password is entered and press enter It
never logins. just reappears.

Pressed Ctrl+Alt+F1 and logedin as root
no commands are accessible, not even 'ls'

Help needed.

Did you update pam and forgot to run revdep-rebuild?  If so use a LiveCD, 
chroot and run revdep-rebuild -v -- --ask

maybe only the environment is somehow broken
try
echo $PATH
or
env

and try using full paths:
/bin/ls  (or /usr/bin/ls)
and
/usr/bin/revdep-rebuild

failing kde login is likely due to a still full disk.

Choice 1) At startup edit your booting line and include as a kernel 
parameter the word 'single'. That may be of some help to get a ready 
prompt. If you're not using GRUB (or if you've configured advanced 
security in GRUB), then you're on your own I guess. Lilo also allows to 
edit the kernel command line, I guess.

Choice 2) If you've configured rc system to be interactive, then press 
'I' when booting and start _only_ extremely necessary services. That 
would also guarantee some ready prompt.

Choice 3) Use a LiveCD and if you _really_ need to execute anything into 
your installation then do it in a chroot.

Whatever your choice is, you can try the following to free up some space 
in your root directory:

1) Delete files under /usr/portage/distfiles.
2) `make clean' under /usr/src/*.
3) Delete /usr/{share/{doc,man},src/*/Documentation} directories. Ok, 
this is desperate, but you can delete all that extremely useful 
documentation. If you can, first copy those dirs to some other media 
like SD or Flash to be able to recover it later.

Those items should have been given you enough space to be able to login 
normally (text based, please!).
Now you have to see what to do to free up some more space (uninstall 
things or something) or give your root partition a breathe and increase 
it's size (you can use the tools of your FS to grow the fs: resize2fs, 
xfs_growfs, etc.).

And in this situation,usually login as root is still possible (as long
as there is reserved space on the disk)

/usr/bin/emerge

Little bit of learning here:

root@smoker / # which emerge
/usr/bin/emerge
root@smoker / #

Now you know where it is and how I found out where it is.  Trick is 
remembering a command you rarely use.  lol

I have never used Fedora, sort of on my bad list at the moment, but you 
should be able to chroot in from about any Linux install.  It should 
work fine just make sure you have the same arch.  Don't boot a 32 bit OS 
and chroot into a 64 bit one.  That can be done but it requires some 
additional commands.

What about the env or echo $PATH output?

Might be that some files used to set up the enviroment are broken.
If PATH and maybe some other things are not set up correctly, that would
explain why login into KDE or anything graphical doesn't work...

You can try 
env-update && source /etc/profile

if that doesn't help, you will have to check the files that are read by
bash, mostyle /etc/profile (which should source /etc/profile.env among
others)


Check also files in users/roots homedir
(~/.bash_profile  / ~/.bashrc), but if the problem happes both with root
and regular user, I don't think the prob. is in those files.

That won't work. The $PATH is broken so the shell can't find ls and
emerge.

Well, it won't find which either :-)

Solution: You run which which and tell the OP which directory contains
which so he can run /path/towhich emerge to find out where emerge is.

Or just use "type -a", because that's a builtin.
~ $ type -a emerge
emerge is /usr/bin/emerge

I always thought that is impossibl because the 32bit libs and kernel are
unable to execute 64bit code. You could do the other way round with no
probs but a 64bit cpu in 32bit mode with 32bit libs and kernel?
I really would like to know more about that.

You could be right.  I know you can do a 32 bit chroot from a 64 bit 
install/media but not sure about the other way around.  I think what I 
was trying to say is that mixing them requires different commands and 
needs to be asked about.  I did a 32 bit install from my 64 bit system 
and it worked fine.  I have not tried the other way around tho.  Maybe 
someone can chime in on if this is possible or not.  Since this is 
Linux, I wouldn't be surprised if it could but it may not be.  I'm not 
sure how to stretch 64 out of 32.

I did that, I had to make a 64-bit kernel, but it found  the libs OK.

Well, if nothing else, you could use binfmt support in kernel to execute
64bit code on 32bit OS, as same as you can execute ARM or other arch
binaries. On the other hand, booting 64bit live system would be much
easier, faster and better approach, I guess :)

If you don't want to mess with chroot from Fedora, you can use Gentoo amd64
Live DVD, which can be downloaded from

http://gentoo.osuosl.org//releases/amd64/11.0/

Except that both won't work in OP's case, because both look for the
executable in directories in PATH which is the OP's problem ;)
