我有一个分配给 /boot 的 512MiB 分区，但 LinuxMint 不断在更新中添加很多内容，现在抱怨磁盘使用情况。
甲df -h写道：
Filesystem Size Used Avail Use% Mounted on
udev 7,8G 0 7,8G 0% /dev
tmpfs 1,6G 9,5M 1,6G 1% /run
/dev/sdb5 48G 13G 35G 27% /

/dev/sdb1 484M 473M 12M 98% /boot
cgmfs 100K 0 100K 0% /run/cgmanager/fs
tmpfs 1,6G 60K 1,6G 1% /run/user/1000
如何清理未使用的内核并保持/boot清洁？

答案1
您可以使用以下命令找出哪些软件包提供了所有内核
dpkg -S /boot/vmlinuz*
这些是占用空间的包/boot。您可以清除不再需要的软件包（通常保留最后两个版本，并确保保留当前运行的内核）。
