Hi

Regarding the new modules that have been added to dracut after v38, and=20
the possible
systemd dependencies, I wonder a bit about this line in the Makefile of=20
dracut in ipfire

https://github.com/ipfire/ipfire-2.x/blob/master/lfs/dracut#L79
rm -rf=20
/usr/lib/dracut/modules.d/*{biosdevname,bootchart,dash,fips*,modsign,busybox,=
convertfs,network,ifcfg,url-lib,gensplash,cms,plymouth,btrfs,crypt*,dm,dmraid=
,dmsquash-live,livenet,lvm,multipath,qemu*,cifs,dasd*,fcoe*,iscsi,nbd,nfs,res=
ume,ssh-client,zfcp*,systemd*,znet,securityfs,masterkey,selinux,usrmount,uefi=
-lib}

I am assuming that is removing dracut modules that one for certain do=20
not need.
I guess some of the new modules introduced between v38 and v56(current)=20
of dracut
should also be but on that "rm" list ?
I.e some new dracut modules depends on systemd, and some are for s390,=20
for example.


I was playing a bit with grep'ing the module-setup.sh files of dracut,=20
to find modules
that depends on systemd for example.
I.e. some way of finding the modules that "at least" should be put on=20
the "rm" list.
I'm unsure if you have any semi automatic way of doing that, or are=20
fully manually needing
to review the modules.

 From what I can see, dracut should fully support being used without=20
systemd, since the modules
are signalling dependencies on systemd.
But modules that are only for s390 for example, needs to be detected=20
manually I think.


The dracut.conf file also has the possibility to omit modules, by the
omit_dracutmodules variable, but that does not seem to be used currently=20
by ipfire.

Alf
