I do not maintain the unit "dbatgdbm" no longer since Gnu-DBM is no more maintained by the FSF (for years, I didn't know).
This is actually false. gdbm is still being maintained. The most recent release (1.8.0) was less than 2 years ago.
There is not a lot of new development on gdbm, but that is a little different than not being maintained.
The current maintainer is listed in the 1.8.0 release.
