rpm doesn't accept wildcards
You can't remove multiple packages matching a certain criteria:
# rpm -e escenic-*
Should remove all packages starting with escenic-, but it does not:
# rpm -e escenic-*
error: package escenic-* is not installed
Thus, you must succumb to writing a while loop to get all those
packages removed:
# rpm -qa | grep ^escenic- | while read p ; do rpm -e $p; done
rpm packages can't contain common directories
DEB files can define directories, but the one-package-one-file is only
enforced on file level, not on directory level. This means that if
your package provides /etc/foo, the package can contain the /etc
directory without any problem on a DEB system. On an RPM system,
however, the package can't contain /etc.
You typically encounter this when you use alien to convert a DEB to
an RPM file. To fix it, you must first generate the .spec file, then
edit it (scripted or not) and then build your RPM.
