用ZFS在Ubuntu 19.10上配置中断grub

Question

我的apt坏了，因为grub配置失败。

看起来grub试图在zfs快照

中发现linux映像。

我使用的是安装程序默认的ubuntu19.10 zfs配置。

又老又没礼貌所以..。

我刚刚遇到了这个问题。结果是索福斯AV扫描仪自动扫描/tmp下的新安装点。这导致了文件系统的锁定。因此，在运行更新时禁用SO磷解决了问题。

添加以下钩子也应该处理未来的问题

root@:/etc/grub.d# ls -tlr *sophos*
-rwxr-xr-x 1 root root 45 Feb  9 13:16 01_sophos
-rwxr-xr-x 1 root root 46 Feb  9 13:16 999_sophos
root@:/etc/grub.d# cat *sophos*
#!/bin/sh

systemctl stop sophos-spl.service
#!/bin/sh

systemctl start sophos-spl.service
