About github.com/opencontainers/runc/libcontainer/user:
According to 195d8d544a
this package has two functions:
- Have a static implementation of user lookup, which is now supported in the
os/user stdlib package with the osusergo build tag, but wasn't at the time.
- Have extra functions that os/user doesn't have, but none of those are used
in homedir.
Since https://github.com/moby/moby/pull/11287, homedir depended directly on
libcontainer's user package for CurrentUser().
This is being replaced with os/user.Current(), because all of our static
binaries are compiled with the osusergo tag, and for dynamic libraries it
is more correct to use libc's implementation than parsing /etc/passwd.
About github.com/docker/docker/pkg/idtools:
Only dependency was from GetStatic() which uses idtools.LookupUID(uid).
The implementation of idtools.LookupUID just calls to
github.com/opencontainers/runc/libcontainer/user.LookupUid or fallbacks
to exec-ing to getent (since https://github.com/moby/moby/pull/27599).
This patch replaces calls to homedir.GetStatic by homedir.Get(), opting out
of supporting nss lookups in static binaries via exec-ing to getent for
the homedir package.
If homedir package users need to support nss lookups, they are advised
to compile dynamically instead.
