Hi. I accidentally deleted directory "/etc/network/if-up.d/". Previously the directory contain:
```
-rwxr-xr-x 1 root root 965 Jan 5 2022 000resolvconf
-rwxr-xr-x 1 root root 358 Feb 18 20:02 avahi-autoipd
-rwxr-xr-x 1 root root 450 Feb 18 19:46 bridgevlan
-rwxr-xr-x 1 root root 499 Feb 18 19:47 bridgevlanport
-rwxr-xr-x 1 root root 298 Feb 18 19:47 chrony
-rwxr-xr-x 1 root root 113 Feb 18 19:39 ethtool
-rwxr-xr-x 1 root root 422 Feb 18 19:48 ifenslave
-rwxr-xr-x 1 root root 169 Feb 18 19:49 mtu
-rwxr-xr-x 1 root root 454 Feb 18 19:50 openvpn
-rwxr-xr-x 1 root root 234 Feb 18 20:08 postfix
-rwxr-xr-x 1 root root 358 Feb 18 20:00 resolved
lrwxrwxrwx 1 root root 32 Aug 6 2024 wpasupplicant -> ../../wpa_supplicant/ifupdown.sh
```
How to manually recreate all the files?
