我一直在尝试将当前的 Debian Jessie 升级到 Stretch。
不幸的是，apt-get dist-upgrade失败时，它返回：
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
systemd : Breaks: udev (< 228-5)
Recommends: libpam-systemd but it is not installed
Breaks: udev:i386 (< 228-5)
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
另外，建议apt --fix-broken install失败：
Do you want to continue? [T/n] t

Preparing to unpack .../archives/udev_232-15_amd64.deb ...
Since release 198, udev requires support for the following features in
the running kernel:
- inotify(2) (CONFIG_INOTIFY_USER)
- signalfd(2) (CONFIG_SIGNALFD)
- accept4(2)
- open_by_handle_at(2) (CONFIG_FHANDLE)
- timerfd_create(2) (CONFIG_TIMERFD)
- epoll_create(2) (CONFIG_EPOLL)

我猜 Stretch 需要比当前内核更新的内核：
~# uname -r
3.2.13-grsec-xxxx-grs-ipv6-64
但尝试安装新的linux-image-*由于udev和systemd问题而失败。
提前致谢！
