Can I generate tags for defined file types only?

[itonohito]

Hi!
Sorry for bothering with possibly newbe question, but is it's possible to create (and use) tags file for defined on .vimrc list of filetypes only? I'd like to have tags for python, php, c etc but I don't need it for system configuration files, bash scripts and so on.

My current easytags config:
set cpoptions+=d
set tags=./.tags;,/.vim/.vimtags
let g:easytags_file = '/.vim/.vimtags'
let g:easytags_async = 1⋅
let g:easytags_dynamic_files = 2 " create and use local tag files instead of global one
let g:easytags_events = ['BufReadPost', 'BufWritePost'] " Update tags on read and save only
let g:easytags_resolve_links = 1
