For example?

It is available on all recent RedHat distributions, Debian 3.1, latest
SuSE and although last time I looked Gentoo is a little behind on their
release and patches it should still work. I also recommend a fairly recent
2.6 kernel in order to get the latest bug fixes. I've fallen somewhat
behind in updating my 2.4 patches but those that are available at

should work adequately.

Preferably 4.1.4 with at least the patches autofs-4.1.4-*.patch from above applied but distributions that have a 4.1 version should

You need to be aware that some maps cannot be browsable (the terminology
is about to change from ghosting). For example

* host:/some/dir/&

is not browsable because autofs cannot know what the map keys at startup.

Basically, if the map keys cannot be known in advance they will not be
seen, at least immediately after startup.
