Bug 318565 – Please add a seperate acl flag to udev

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Thomas 2010-05-05 10:08:14 UTC]

The (indirect) prerequisites for the new gnome desktop is acl, which is unnecessary.  It is being pulled in by udev's "extras" flag.  Please add a seperate acl flag to udev to be able to switch off acl altogether.

Reproducible: Always

Steps to Reproduce:
1. Try to emerge gnome 2.28 with sys-apps/acl masked

Actual Results:  
Unnecessary conflict

Expected Results:  
Installation of gnome without acl support

udev upstream does not have a separate ACL enable/disable at the configure level.

configure usually has some magic to auto-detect the presence of virtually any given library.  Although relying on this would mean, that you couldn't switch it off by -acl if it happens to be around anyway.

        AC_CHECK_LIB([acl], [acl_init], [:], AC_MSG_ERROR([libacl not found]))
        AC_CHECK_HEADER([acl/libacl.h], [:], AC_MSG_ERROR([libacl header not found]))

udev is not in the "usually" category.  If you enable extras, the configure wants everything to be there.

You are right, they really mean it. ;-)  The modem component of udev also requires acl, so it has to be switched off, too.  The patch below against udev-149 allows for the compilation of extras without acl being used.

Patch against udev-149 to get rid of acl dependencies

[Comment 6 Matthias Schwarzott 2011-06-30 20:05:29 UTC]

udev-171 has extras split, so there now is a use-flag acl.
