If acct-user/man is emerged with FEATURES=noman, the install fails as follows: --8<-- >>> Install acct-user/man-0 into /usr/arm-linux-gnueabihf/tmp/portage/acct-user/man-0/image >>> Completed installing acct-user/man-0 into /usr/arm-linux-gnueabihf/tmp/portage/acct-user/man-0/image * Final size of build directory: 4 KiB * Final size of installed tree: 16 KiB >>> Done. >>> Installing (1 of 1) acct-user/man-0::gentoo to /usr/arm-linux-gnueabihf/ chown: cannot access '/usr/arm-linux-gnueabihf/tmp/portage/acct-user/man-0/image/usr/share/man': No such file or directory * ERROR: acct-user/man-0::gentoo failed (preinst phase): * fowners failed --8<-- While trying to install acct-user/man with FEATURES=noman might seems like a crackpot thing to do, it actually isn't -- @system depends on virtual/man from whence there is a dependency chain back to acct-user/man (via sys-apps/man-db), so on a system where noman is enabled globally it is possible to end up in this situation. Workarounds include emerging acct-user/man specifically with FEATURES=-noman, or using sys-apps/man (which does not depend on acct-user/man) instead of sys-apps/man-db to satisfy virtual/man. The error message reproduced above does not give much help in finding these solutions though. :-)
