Same comment ;)

I find sometime confusing the see which GitLab features are restricted
to the paid version and which are available for open source projects.

Some users hide their email on launchpad, so we would be hard to simply
re-import their bug on gitlab. Now if you ask them to import it, it is
easier. 60 days seem enough to react.

Something that always bugged me on launchpad is you can not Cc other
people on a bug if they don't have a launchpad account. I haven't
checked if GitLab allows that (Bugzilla does).

We should do some experiments first, because I saw various ways to use
the GitLab ticket tags, and none convinced me it is practical.

Should anyone add any tag? Should we restrict to a set of useful tags?

Current launchpad tags:

    35 arm
    21 linux-user
    17 qemu
    16 ppc
    15 windows
    13 testcase
    11 tcg
    9 mips
    9 usb
    9 qemu-img
    6 i386
    6 feature-request
    2 sh4
    2 patch
    1 s390x
    1 sparc

The patterns I see:

- user-mode vs softmmu
  (linux-user)

- one tag per architecture
  (arm / ppc / mips / i386 / sh4 / s390x / sparc)

- host OS
  (windows)

- accelerator
  (tcg)

- subsystem
  (usb)

- tools
  (qemu-img)

- feature requests

- testcase

I suppose tags are hints to maintainers, so keeping something similar to
the MAINTAINERS file separation could be useful.
