[Rpm-maint] [rpm-software-management/rpm] %transfiletriggerpostun is not executed (Issue #3048)

Thu Apr 18 10:46:13 UTC 2024

I have a package with the a few file triggers:
```console
$ rpm -q --filetriggers filesystem|grep -w using -A1
filetriggerin scriptlet (using <lua>) -- /usr/bin
print('FILETRIGGERIN start')
--
filetriggerpostun scriptlet (using <lua>) -- /usr/bin
print('FILETRIGGERPOSTUN /usr/bin start')
--
filetriggerpostun scriptlet (using <lua>) -- /sbin, /usr/sbin
print('FILETRIGGERPOSTUN /usr/sbin start')
--
transfiletriggerpostun scriptlet (using <lua>) -- /sbin, /usr/sbin
print('TRANSFILETRIGGERPOSTUN start')
```
The two last triggers are for the same paths, so if one fires, the other must too, right?

```console
$ ls -l $(find /usr/sbin/ -type f)

-rwxr-xr-x. 1 root root 2792336 Feb 27 01:00 /usr/sbin/pdata_tools

```

As you can see, the TRANSFILETRIGGERPOSTUN is not called, even tough `/usr/sbin/{kpartx,pdata_tools}` have been uninstalled and replaced by symlinks generated by FILETRIGGERPOSTUN.

I don't have a very simple reproducer for this, but I snapshotted the VM before running the commands above, so I can reproduce them fairly easily.

The issue also occurs with dnf. I repeated the process with rpm to make sure that dnf is not suppressing scriptlet output or otherwise interfering. rpm is patched to have %_sbindir==/usr/bin, but I hope this doesn't affect scriptlets ;)
