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
kmod replaced module-init-tools, which was EOL'ed in 2011. All the tools were
rewritten on top of libkmod and they can be used as drop in replacements.
Along the years there were a few behavior changes and new features implemented,
following feedback from Linux kernel community and distros.
