Description Pandu E Poluan 2011-09-06 06:28:24 UTC 
revdep-rebuild gives up when it can't find /var/cache/revdep-rebuild.

revdep-rebuild runs well after I manually re-create /var/cache/revdep-rebuild.


Reproducible: Always

Steps to Reproduce:
1. rm -rf /var/cache/revdep-rebuild
2. revdep-rebuild

Actual Results:  
 * Configuring search environment for revdep-rebuild
 * Unable to find a satisfactory location for temporary files (/var/cache/revdep-rebuild)


Expected Results:  
 * Configuring search environment for revdep-rebuild
 * Checking reverse dependencies

... and so on ...

According to FHS, "The application must be able to regenerate or restore the data [in /var/cache]". So, IMO revdep-rebuild should first attempt to create /var/cache/revdep-rebuild before giving up (e.g., if for some reasons /var/cache becomes read-only)
Comment 1 Pandu E Poluan 2011-09-06 06:37:12 UTC 
This misbehavior still exists in app-portage/gentoolkit-0.3.0.4-r3.

This is a duplicate of bug #358073 

Since revdep-rebuild is getting an all-python rewrite, should test with release candidate.

I'm now using app-portage/gentoolkit-0.3.0.4-r4, and still revdep-rebuild commits suicide when /var/cache/revdep-rebuild does not exist.

 * Configuring search environment for revdep-rebuild
 * Unable to find a satisfactory location for temporary files (/var/cache/revdep-rebuild)

And a simple `mkdir -p /var/cache/revdep-rebuild` still fixes the problem.
Comment 6 Paul Varner (RETIRED) gentoo-dev 2012-02-29 16:17:33 UTC 
This won't be fixed until we move to the python version of revdep-rebuild in gentoolkit-0.3.1.  

The current behavior is by design for the bash version of revdep-rebuild.
