[gentoo-commits] gentoo-x86 commit in sys-fs/udev: ChangeLog udev-9999.ebuild udev-136.ebuild

[Matthias Schwarzott (zzam)]

zzam        09/01/20 13:00:01

  Modified:             ChangeLog udev-9999.ebuild
  Added:                udev-136.ebuild
  Log:
  Version bumped. This raises kernel version for reliable udev usage to 2.6.20. Backported one patch. The upstream rule changes still need to be reviewed. For now keep using group uucp instead of dialout as suggested by upstream. Move init-script stuff into a subdir for FILESDIR. Small changes to shell-compat logic.
  (Portage version: 2.1.6.6/cvs/Linux 2.6.27-gentoo-r1 i686)
