[gentoo-dev] Sanity check: enewuser in binpkg with portage-utils

[gentoo-dev] Sanity check: enewuser in binpkg with portage-utils

[Peter Stuge]

Hi,

I have some ebuilds which use enewuser to create groups and users in
pkg_setup(), and make use of those groups and users in src_install()
in exeopts, insopts etc.

Is there any reason that this would not always work reliably with
binpkgs?

Ie. regardless of whether I am using portage or portage-utils to
install binpkgs with such pkg_setup() and src_install() combinations?

Should it matter if the groups and users already exist? I expect no.

I would expect it to always work reliably, because exeopts/insopts
user and group arguments are looked up by install at run time.

I think I had a problem with this yesterday, but I can't reproduce it.


Thanks

//Peter

Hi,

keep in mind that when installing a binpkg, src_* functions are skipped,
see https://devmanual.gentoo.org/ebuild-writing/functions/

So when you are doing anything with the actual user, you have to do that
in a pkg_* function.

In case of "exeopts", if you do something like

  exeopts -m 6710 -g plgudev

in any src_* function, the created image will use the GID/UIDs from the
system used to create the binpkg. This is probably your problem...

Make sure to adjust permissions in pkg_* functions!

No. This is entirely wrong and insane. Tar stores user and group names, and restores them correctly.

Oops, thanks for correction.
