#kmod on irc.freenode.org
+
+Compatibility with module-init-tools
+====================================
+
+kmod replaces module-init-tools, which is end-of-life. Most of its tools are
+rewritten on top of libkmod so it can be used as a drop in replacements.
+Somethings however were changed. Reasons vary from "the feature was already
+long deprecated on module-init-tools" to "it would be too much trouble to
+support it".
+
+There are several features that are being added in kmod, but we don't
+keep track of them here.
+
+modprobe
+--------
+
+* 'modprobe -l' was marked as deprecated and does not exist anymore
+
+* 'modprobe -t' is gone, together with 'modprobe -l'
+
+* modprobe doesn't parse configuration files with names not ending in
+ '.alias' or '.conf'. modprobe used to warn about these files.
+
+* modprobe doesn't parse 'config' and 'include' commands in configuration
+ files.
+
+* modprobe from m-i-t does not honour softdeps for install commands. E.g.:
+ config:
+
+ install bli "echo bli"
+ install bla "echo bla"
+ softdep bla pre: bli
+
+ With m-i-t, the output of 'modprobe --show-depends bla' will be:
+ install "echo bla"
+
+ While with kmod:
+ install "echo bli"
+ install "echo bla"
+
+* kmod doesn't dump the configuration as is in the config files. Instead it
+ dumps the configuration as it was parsed. Therefore, comments and file names
+ are not dumped, but on the good side we know what the exact configuration
+ kmod is using. We did this because if we only want to know the entire content
+ of configuration files, it's enough to use find(1) in modprobe.d directories
+
+depmod
+------
+
+* there's no 'depmod -m' option: legacy modules.*map files are gone
+
+lsmod
+-----
+
+* module-init-tools used /proc/modules to parse module info. kmod uses
+ /sys/module/*, but there's a fallback to /proc/modules if the latter isn't
+ available
