Commit a70b06857fc83ef6f85a6c06b3478c0c25ec8fdaa70b06857fc83ef6f85a6c06b3478c0c25ec8fda modified /etc/bash/bashrc such that it no longer exports $LS_COLORS if it would be identical to the built-in database used by “dircolors -b” with no filename. The problem is that this means I no longer have coloured ls output. I didn’t modify my database locally, but I liked the defaults. Before this commit, $LS_COLORS would be set to the default string and I would get colours by file extension. Now $LS_COLORS is unset, and I don’t get colours by file extension.
i meant to fix this, but it fell by the wayside
i guess i read too much in the documentation for ls/dircolors and not enough of the source. if LS_COLORS isn't set, then `ls` will only colorize by file attributes (e.g. dir, sock, +x). it won't load/use the dircolors database automatically. https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=e034ed6fa7205737661467cc148fadba79d7fec8
