emerge sync + emerge portage -> bash:- * no such file or

[boglin]

I cannot execute any command on my remote system, or create a new ssh-session. Please help me...

I logged in to update some packages and did emerge sync and an emerge -av portage. Portage told me I needed a new version:

Code: Select all

These are the packages that I would merge, in order:

Calculating dependencies ...done!
[ebuild     U ] sys-apps/portage-2.0.50-r11 [2.0.50-r9] -build -multilib -(selinux)  218 kB

Portage installs the new version of itself,

Code: Select all

>>> Regenerating /etc/ld.so.cache...
 * Caching service dependencies...
>>> sys-apps/portage-2.0.50-r11 merged.

 sys-apps/portage
    selected: 2.0.50-r9
   protected: 2.0.50-r11
     omitted: none

>>> 'Selected' packages are slated for removal.
>>> 'Protected' and 'omitted' packages...

But dies with:

Code: Select all

And then, even a simple ls results in:

Code: Select all

-bash: /bin/ls: No such file or directory

, with similar results for any command you can think of. But not the shell-internal ones like 'echo'.

So I was left with a completely unusable system. I was unable to ssh into the system: a connection was established and the password cleared but the remote host reported that /bin/bash did not exist. I can't execute anything in the ssh session that is still open...

Please help.

I just ran into this problem trying to install a fresh system off the 2004.3 LiveCD. I ran into it about a year ago on a much earlier Gentoo version and submitted a bug report which was never resolved because by the time they looked at it, a couple revs had rolled in everything and it wasn't reproducible.

On the chance that the same bandaide would fix it again, I went into my /etc/make.conf and set

Code: Select all

AUTOCLEAN="no"

Apparently, what is happening is the emerge of the kernel is throwing the baby (bash, emerge and all kinds of /bin apps) out with the bathwater, and the only way to get them back as far as I know is to boot off the LiveCD again and untar them. But once you turn off autocleaning, the problem goes away and you can finish your install.
