Subject: [PATCH 3/5] Fix root relocation regression
|
|
|
|
When relocating the root directory, make sure we insert the new path's
|
|
dirname to dirNames[] even if the root itself is owned by the package.
|
|
|
|
This appears to have been the intention from the first version (largely
|
|
untouched since) of this code as we allow the root to pass through the
|
|
first checks (by setting len to 0 in that case) as well as the second
|
|
for loop where we do the relocations.
|
|
|
|
This allows fsm to properly create and remove the relocated directory
|
|
since we're now using fd-based calls (#1919) and the parent directory
|
|
needs to be opened first.
|
|
|
|
No need to do string comparison here, the empty basename signals that
|
|
we're processing the root directory, so just use that.
|
|
|
|
Building a relocatable package that owns the root directory seems to be
|
|
a handy way to create user-installable packages (see RHEL-28967) and it
|
|
happened to work before with the path-based calls so this technically
|
|
was a regression. Add a test that emulates this use case.
|
|
|
|
Backported from commits:

|
|

|
|
|
|
Tests are excluded from this backport since they would need significant
|
|
rework, the use case will be covered by Beaker.

Fixes: RHEL-49494
