wsl2 /bin/sed: cannot rename etc/sedPisP47: Permission denied

解决方式：

修改sed的选项

解释:

sed -i -e COMMAND FILE sed: cannot rename /tmp/sed87A28d: Permission denied
*
This occurs most often when there are multiple processes running sed -i on files located in the same directory.
*
The file that sed is complaining about can be in the /tmp directory, the $TMP directory, or in the same directory as the file being edited.
*
One way to prevent this error is to use the -i option with an argument. For example, the following will create a backup of FILE by appending “.bak” to the name: sed -i.bak -e COMMAND FILE

buildroot遇到编译类似的问题，可手动将package下对应包的package.mk临时修改一下

$(SED) ‘/^# %sudo\\tALL=(ALL) ALL/s/^# //’ $(TARGET_DIR)/etc/sudoers

其他解决的思路

比如确实是遇到权限问题，比如多进程占用的问题，参见github and stackoverflow的讨论

可能真的是wsl2的问题？？
