My node /var/cache is actually a symlink to /mnt/usb/var/cache, because my solid-state disk is too small. This breaks revdep-rebuild, as follows: root@infty ~ # revdep-rebuild -v * Configuring search environment for revdep-rebuild * Working directory expected to be /var/cache/revdep-rebuild, but it is /mnt/usb/var/cache/revdep-rebuild root@infty ~ # Reproducible: Always Steps to Reproduce: 1. su - 2. <enter> 3. revdep-rebuild 4. <enter> ;) Actual Results: See above. Expected Results: When When I execute the command as an ordinary user, with "pretend" and "verbose" options on, it seems to work just fine. Here's the proof: joe@infty $ revdep-rebuild -p -v * Configuring search environment for revdep-rebuild * Temporary cache files are located in /tmp/revdep-rebuild.HGVNAmzSg2 revdep-rebuild environment: SEARCH_DIRS="/bin /lib /opt/bin /sbin /usr/bin /usr/i686-pc-linux-gnu/gcc-bin/4.1.2 /usr/i686-pc-linux-gnu/lib /usr/lib /usr/lib/gcc/i686-pc-linux-gnu/4.1.2 /usr/lib/opengl/xorg-x11/lib /usr/libexec /usr/local/lib /usr/sbin" SEARCH_DIRS_MASK="/lib/modules" LD_LIBRARY_MASK="libjava.so libjvm.so libodbc.so libodbcinst.so" PORTAGE_ROOT="/" EMERGE_OPTIONS="" ORDER_PKGS="1" FULL_LD_PATH="1" * Checking reverse dependencies * Packages containing binaries and libraries broken by a package update * will be emerged. * Collecting system binaries and libraries * Generated new 1_files.rr * Collecting complete LD_LIBRARY_PATH * Generated new 2_ldpath.rr * Checking dynamic linking consistency [ 100% ] * Dynamic linking on your system is consistent...

You will need to bind mount /var/cache directory. The code that checks for symlinks was put in at the request of the security team to prevent symlink attacks. *** This bug has been marked as a duplicate of bug 234271 ***
(In reply to comment #1) > You will need to bind mount /var/cache directory. Thank you. I will do this instead of symlinking. For other noobs who read this and want details, my plan is to .. delete the symbolic link whose name was /var/cache, .. create a new empty directory named /var/cache, and then .. mount --rbind /mnt/usr/var/cache /var/cache The third line by itself will probably suffice for users who haven't disturbed the default setup like I did.
Sorry, I mistyped one character: (old/wrong)> .. mount --rbind /mnt/usr/var/cache /var/cache (new/right)> .. mount --rbind /mnt/usb/var/cache /var/cache
how do you solve this on boot? what should one put in /etc/fstab in order for this to work? or should one use /etc/rc.local ? My entire /var is symlink to a directory on an ecrypted filesystem, how can I solve the same problem?
