Thank you for chiming in.


, but the C preprocessor
(CPP) is indeed required by xrdb (that's an option in xrdb, see "-cpp"
in man xrdb) and xrdb itself is required by GDM:
https://src.fedoraproject.org/rpms/gdm/blob/rawhide/f/gdm.spec#_80

GDM uses xrdb from its data/Init.in and data/Xsession.in:

https://gitlab.gnome.org/GNOME/gdm/-/blob/main/data/Xsession.in#L118-129
https://gitlab.gnome.org/GNOME/gdm/-/blob/main/data/Init.in#L31-34

Please note that these commands all use "xrdb -nocpp" so cpp is not
actually used there, but the package dependencies still pull it of
course.
xrdb does not hard-depend on cpp, only recommends it:
$ rpm -qR xrdb |grep cpp
$ rpm -q --recommends xrdb
cpp
$


Right, that is why I have not noticed there actually is some (weak) dependency installed on my system removing the CPP package.

Nevertheless, I still wonder, should the cpp be installed by default? Can we exclude it somehow? Probably in kickstart. On my previous system I have removed it probably years ago and I am not aware of any issue. (With exception of GDM) does anybody using `xrdb` for anything where the CPP is really needed?
