If we set ACCT_USER_ENFORCE_ID=true in ftp-0.ebuild and then "emerge |
16 |
acct-user/ftp" again, the second one dies with |
17 |
|
18 |
* The required UID is already taken by another user. |
19 |
* UID: 21 (needed for ftp) |
20 |

This prevents "emerge -e @world" from working, and would prevent an |
22 |
upgrade to ftp-1.ebuild in the future. |

We could augment the checks to ignore the existing user/group if its |
25 |
name agrees with the one we're trying to create, but now I'm having deja |
26 |
vu. I think this is another reason why I decided to go with a dummy file |
27 |
installed under /var/lib to catch collisions: the PM will necessarily |
28 |
ignore collisions from the same package. |
