Description Michael Lawrence 2015-04-30 17:15:12 UTC
USER can call them in buy USE="" as normal if enabled 
IE zfs?  ( sys-fs/zfs ) however portage will use for QA or rev-dep rebuilds 
IE Install sshfuse and it will rebuild packages which can use it as an optional. if asked to , 

this is just a proposal/s for down the line for a few options to possibly make life easier 

iREC can recommend best flags to user ie a quick elog message to user these are best IUSE setings I find useful (free to do what ever) 

Reproducible: Didn't try

Steps to Reproduce:
I've included a sample ebuild in html and txt with some ideas , 
Actual Results:  
opdeps eclass for better optional depends handling and or QA checks, 
packages that add more usefulness to a given package but not required to use 

Expected Results:

 inherit qmake-utils versionator ODEPENDS , ?
inherit_propasl odeps eclass 

revdep-rebuild could graciuly rebuild when called against the optional depends when asked too.

 DESCRIPTION="Qt4 frontend for fsarchiver"

 KEYWORDS="~amd64 ~x86"

 IREC="+onbydefault +btrfs +jfs +ntfs reiser4 +reiserfs +xfss +sshfs nfs samba"
### I rec, I RECOMEND like IUSE but more a suggestion for optimal experience ie elog for best optimal results in most cases, though not required… 

Portage offer with flags Y/N or M_inimal just use the basics.  Or Yes for optimal NO for basics, 


Portage: It’s highly recommended to Use these flags for best possible experience, though not required; do you agree: Y/N or M_inimal, or you can override with USE=”+your-flags”


If I had a fancy script to to re-bake app-admin/systemrescuecd I’d add damb near everything, with a lice cd option but that’s above my Ebuild skill level atm. 

       Why odepends , I can declare them , if not installed user can USE="+flags " and pull in added features 
       though not required , it also perhaps might ease QA Frustrations. Of having to pound them into metadata.xml

ebuild in html

mainly this is a no hurry option for ebuild maintainers 
 FUGGLY metadata , officially my package supports nfs samba but unofficially 
if its a network file system on the backend that works ie Openafs 
etc its fair game if mounted as a filesystem , ftpfuse httpfuse etc , 
but i've just put in main ones , 

anyhow I was thinking off the top of my head ,  there has to be a cleaner way than the metadata.xml for optional flags , and to keep QA folks  happy too.

Anyhow its a Proposal for adding a specific cat in ebuilds for optional depends  IE samaba?  ( net-fs/samba ) though not required to build at least can offer them in a safe manor for more user choice. 
chances are most users have already , 

but on a FRESH install why not give them the option of adding in enhancements as a convenience ?

plus user can just call in ODEPS wanted , IE on a clean install etc. 

plus its less f'uggly than the metadata xml 
and at the very least if declared but not called for IUSE in a package portage happy repoman happy 
openssl gnutls etc " QA happy 
portage will know its an optional for QA useage less called into IUSE and will give 2 rats behinds less needed about ODEPS but for ELOG purposes/msg  and yup these package are optional bla bla make using "PAK-name-hear" all the bla bla better. 

anyhow its no big deal but was just a idea to kick about a bit. 

-----so fuggly.....---------------
<flag name='btrfs'>Enable support for <pkg>sys-fs/btrfs-progs</pkg></flag>
<flag name='jfs'>Enable support for<pkg>sys-fs/jfsutils</pkg></flag>
<flag name='ntfs'>Enable support for <pkg>sys-fs/ntfs3g[ntfsprogs]</pkg>
