我一直在努力解决 systemd 和 python 问题（我无法更新我的电脑）。我已经解决了这些问题，但最后，我无法运行reboot命令行。我尝试重新创建符号链接，但/sbin/reboot文件夹似乎是空的……
我认为这可能是一个大问题。
reboot当命令未知时，我可以安全地重启计算机吗？我该如何解决这个问题？

# Note that configuration options from this file can be overridden
# by config files in the /etc/initramfs-tools/conf.d directory.
#
# MODULES: [ most | netboot | dep | list ]
#
# most - Add most filesystem and all harddrive drivers.
#
# dep - Try and guess which modules to load.
#
# netboot - Add the base modules, network modules, but skip block devices.

# list - Only include modules from the 'additional modules' list

# BUSYBOX: [ y | n | auto ]

# Use busybox shell and utilities. If set to n, klibc utilities will be used.
# If set to auto (or unset), busybox will be used if installed and klibc will
# be used otherwise.

# Amount of RAM to use for RAM-based compressed swap space.

# An empty value - compcache isn't used, or added to the initramfs at all.
# An integer and K (e.g. 65536 K) - use a number of kilobytes.
# An integer and M (e.g. 256 M) - use a number of megabytes.
# An integer and G (e.g. 1 G) - use a number of gigabytes.
# An integer and % (e.g. 50 %) - use a percentage of the amount of RAM.

# You can optionally install the compcache package to configure this setting
# via debconf and have userspace scripts to load and unload compcache.
