9 Portage seems OK with the missing dependency, but for the overall plan
10 to work, you have to wait a long time before deleting virtual/emacs;
11 otherwise the upgrade path is broken. With virtual/emacs-26 installed
12 and "old" copies of the elisp ebuilds installed, you get unsatisfied
13 dependencies switching from emacs-vcs to a live slot of emacs. Everyone
14 in that situation must update to virtual/emacs-26-r1, which they can't
15 do after you delete it.
17 And of course you can't mask virtual/emacs in the meantime, because that
18 does kill the PM.
20 New revisions would still be the sane solution, now and in the future,
21 because they don't require investigative journalism to uncover exactly
22 what might go wrong when we bend the rules /this time/. They also don't
23 impose a cutoff date after which upgrading users are screwed. You just
24 automate the revbumps, commit them all at once, and make a pull request
25 against CI to verify that nothing is too borked.
