[srgvg]

Request for comments: I could use some input on validating the update version parameters, as I don't actively use this role myself any more.

• confirm deployment on Centos 6 and 7 works (never used those myself)
• confirm deployment on Debian and Ubuntu - recent distributions - is still working
• confirm latest versions of ansible work (I upped the min version to 2.5, quite arbitrarily)

Hence pinging all contributors and users who interacted with this repo: @ix5 @gronke @corny @JocelynDelalande @adriankirchner @tjanez @lexrus @tivvit @adeel @fw8 @wizonesolutions @zealot128

@srgvg Hello, not using it anymore neither, sorry.

If no one answers and confirm, maybe, better put a bold notice in ansible-galaxy and github stating that this role is seeking for maintainership :).

Thanks for your work so far !

I am willing to help maintain it, still using it in my small org and not completely on board with the whole docker thing yet.

Regarding the version compatibility, see my comment on #30

Interesting. I can't approve my own PR's, which is good :-) @JocelynDelalande @ix5 If you want to have a look, I could make a new release on Galaxy. BTW, if you are stil interested, I'm willing to open up your access on this repo to help maintain it.

[JocelynDelalande]

No longer using this role, sorry :-)

Also just handed over our org's seafile installation to an, ahem, unsuspecting victim, sorry.
Seems docker is the way forward.
