madonuko created an issue (rpm-software-management/rpm#3691)
**Describe the bug**
`glibc` is not present during `%pre` (which requires bash). This causes `error:
failed to exec scriptlet interpreter /bin/sh: No such file or directory`.
While you may wonder in what case does `glibc` not exist: we (Ultramarine
Linux) build our images from scratch with
[dnf4](https://github.com/Ultramarine-Linux/images/actions/runs/14074642779/job/39415343794#step:6:5446)
and
[dnf5](https://github.com/Ultramarine-Linux/images/actions/runs/14074642779/job/39415343869#step:6:4280),
both fails to install `glibc` before `crypto-policies` and `dbus-common`.
Fortunately libsolv is deterministic given the same packages, so this issue
wasn't discovered in upstream Fedora and other distributions simply due to pure
luck ;)

Jokes aside…
**To Reproduce**
Steps to reproduce the behavior:
1. Download glibc-common [from
here](https://koji.fedoraproject.org/koji/buildinfo?buildID=2663025)
2. `rpmrebuild -enp glibc-common-2.41-1.fc42.x86_64.rpm` then add something
like `Requires(pre): crypto-policies`
3. `sudo dnf in -y --installroot=/newroot --use-host-config
./glibc-common-2.41-1.fc42.x86_64.rpm --nogpgcheck --releasever=42`
4. Alternatively `sudo dnf4 in -y --installroot=/newroot
./glibc-common-2.41-1.fc42.x86_64.rpm --nogpgcheck --releasever=42`
Please link or attach the packages or spec files involved.

**Expected behavior**
The depsolver should install `glibc` before any package that requires the
scripts.
**Output**

**Environment**
- OS / Distribution: Fedora 42
- Version 4.20.1
**Possible solutions**
- Automatically add glibc as a dependency for packages with scriptlets (that
uses anything but <lua>) in `rpmbuild`?
- Install `glibc` with the highest possible priority in the depsolver?
- Find `/bin/sh` properly?
