Description ta2002 2020-05-16 21:46:24 UTC
No doubt someone will want to rewrite the title of this. :)

Anyway, I have (on two machines) util-linux installed with the cryptsetup USE flag. After the update from json-c-0.13.1-r1 to json-c-0.14-r2 (which replaces with portage no longer works, because the mount command (used by pid-sandbox) fails due to its dependency on (again, this will only happen when util-linux has the cryptsetup USE flag set).

I think I can recover from this, but the json-c-0.14-r2 ebuild should if (util-linux has cryptsetup support) leave around (with instructions to remove later) and require the rebuild of util-linux after the update.

util-linux does not use libjson-c directly. libjson-c probably gets pulled in by libcryptsetup. Rebuilding sys-fs/cryptsetup should resolve the issue.

sys-fs/cryptsetup already uses a slot-operator for the dev-libs/json-c dependency, which should trigger an automatic rebuild of the former when the latter is upgraded.

As well, the preserve-libs Portage feature should prevent from being removed until the rebuild occurs.

Have you disabled FEATURES="preserve-libs"?

/bin/mount is unable to operate once json-c goes from .so version 4 to .so version 5.

emerge is unable to operate on this system once /bin/mount is crippled in this manner.
